# PURPOSE

This Guide provides information for the proper application of the ASME
B31.3 Code \"Process Piping," 2002 version. ASME B31.3 applies to
process piping and tubing systems at Los Alamos National Laboratory
(LANL). This Guide also contains ASME B31.1 and AWWA compliant Piping
Specifications. Guide users are responsible for compliance with all
aspects of the applicable Code. This Guide addresses only B31.3, however
this guidance is typical of the requirements of other piping Codes.

The information contained in this Guide provides clarification to the
Code text, additional information not contained in ASME B31.3, and
design input specific to LANL. **This Guide is not to be used as a
stand-alone document.** This Guide is formatted to be used in
conjunction with ASME B31.3, by following the same section numbering as
B31.3 Code. Appendix references herein are to this Guide, not B31.3 or
ESM Chapter 5 Section D20, unless otherwise noted.

A user who desires clarifications on the application of piping related
Codes and Standards should contact the LANL Engineering Standards
Mechanical Point-of-Contact.

# B31.3 INTRODUCTION

The Introduction to ASME B31.3 states \"It is the owner\'s \[Design
Authority\] responsibility to determine which Code Section is most
applicable to the piping installation."

The other ASME B31 Code Sections and other common National Consensus
Codes are listed in Table 1. Building and plumbing Codes as required by
state and local jurisdictional requirements apply to potable water, and
for sewer and drain systems that do not have a process function.

**Guidance supplementing the Code** is necessary because the Code
provides no explicit rules for functional design, material compatibility
with fluid and environment (erosion/corrosion protection, radiation
effects, etc.), layout, serviceability, steam tracing, grounding, valve
and component selections, design of pipe supports, material
traceability, gasket selection, as-built tolerances, insulation,
cleaning for special process, etc. Also, for certain services some
options available through B31.3 must be excluded, made more stringent or
supplemented by the designer.

**Warning:** The original and continued safe operation of a piping
system depends on the competent application of codes and standards.

The **Owner and Designer are responsible** for compliance with the
personnel and process qualification requirements of the codes and
standards.

In particular, the application of ASME B31.3 requires compliance with
the **Inspector** qualification requirements of ASME B31.3 Section VI
for all fluid services (safety or non-safety related).

# I - SCOPE AND DEFINITIONS

## 300(b) - Responsibilities

The following responsibilities are applicable at LANL:

    in Category D fluid service.

12) Examiner - The person(s) certified by the employer as qualified to
    perform the quality control functions specified in ASME B31.3. The
    LANL QA Division designates LANL Examiner(s).

# II - DESIGN

## 301.1 - General

Of all the design considerations listed in 301, only [pressure
rating]{.underline} is covered in the Piping Specifications in Appendix
A. The Piping Specifications provide materials, fittings, and fasteners,
which meet the pressure design requirements of B31.3. The designer must
address all design conditions.

## 301.2.2 - Required Pressure Containment or Relief

Piping systems are designed to either safely contain or relieve the
maximum pressure that can be imposed. Plant fires can present a safety
concern for certain piping systems. The installation of pressure relief
devices should be considered for liquid systems greater than 6" ID that
can have isolated fluid.

Helpful information is available on the [LANL pressure safety
webpage](http://int.lanl.gov/safety/pressure/index.shtml). Also, per LIR
402-1200-01, users must contact the Pressure Vessel and Piping Committee
(PVPC) and/or Cryogenic and Liquefied Gas Safety Committee (CLGSC)
regarding systems requiring relief devices.

## 301.5.1 - Impact

Piping systems must be designed to withstand anticipated fluid
transients (waterhammers, pressure surges, etc.). These are the
transients expected to occur during normal operation of the system.
Piping systems cannot be designed for unanticipated transients. These
are the transients that can occur if the system is not properly
operated. Unanticipated transients must be eliminated by design (layout)
and appropriate startup and operating procedures.

## 301.5.2/3- Wind and Earthquake

The applicable wind and earthquake requirements are defined LANL
Engineering Standards Manual Structural Chapter 5.

## 301.5.4 - Vibration

New designs, modifications, repairs, replacements, should be visually
inspected at startup to verify that vibration is not excessive. The
rules of ASME \"Standards and Guides for Operation and Maintenance of
Nuclear Power Plants\" OM-S/G, Part 3, can be used for guidance. The
ASME OM document provides a methodology to evaluate vibration using high
cycle fatigue analysis and can be applied to any piping system.

## 301.8 - Effects of Support, Anchor, and Terminal Movements

Soil settlement can adversely affect the integrity of a piping system
and the flow in a sloped line. When proper slope is required to maintain
flow in an underground piping system, soil settlements need to be
evaluated in the design of the piping system.

## 302.2.1 - Listed Components Having Established Ratings

Tables 326.1, A326.1, and K326.1 provide a listing of standards and
specifications that have been accepted by the Code. Some of these
standards provide established pressure/temperature ratings for
components (e.g., ASME B16.5). The components may be used in piping
systems within the specified ratings without additional analysis. If
these components are used outside established ratings additional
analysis is required.

## 302.2.2- Listed Components Not Having Specific Ratings

Some standards and specifications provided in Tables 326.1, A326.1, and
K326.1 base pressure/temperature ratings on equivalent schedule (wall
thickness) of straight seamless piping less mill tolerance (e.g., ASME
B16.11). The ratings of these components are addressed in the piping
specifications provided in Appendix A. If these components are used
outside the limits established in the piping specification additional
analysis and documentation must be provided.

## [302.2.3 -]{.smallcaps} Unlisted Components

The ASME B31.3 Code defines unlisted components as components not in
Tables 326.1, A326.1, or K326.1. Unlisted components can have pressure
ratings but the owner and/or the designer has the responsibility to
verify that the design, materials, fabrication, examination, and testing
of the component meet the requirements of ASME B31.3. Unlisted
components are generally categorized as one of the following:

 Components built to Unlisted Published Standards,

 Components built to Manufacturers Standards, or

 Components built to Site Standards or Engineering Design.

Each of these categories is addressed below.

### Components Built to Unlisted Published National Standards

Components built to other published National Standards may be used
provided that the design, material, fabrication, examination, and
testing have been verified to meet the requirements of ASME B31.3. The
Code states that the pressure design must meet the requirements of
paragraph 304 of B31.3. The rules described below for components
fabricated at LANL should be followed when published National Standards
are not acceptable.

### Components Built to Manufacturers Standards

Components built to Manufacturers Standards have not been established by
a consensus body and require a more detailed review than components
built to Published National Standards. Many manufacturers build
components for application in ASME B31.3 piping systems therefore,
evaluations of the design, materials, fabrication, examination, and
testing to B31.3 requirements is less difficult.

The pressure/temperature design of the component should provide the same
safety margins as the Code. When evaluating these components the
manufacturers should be contacted to determine what documentation is
available for the components. Suppliers or distributors of the component
may not understand the Code and may not be helpful in resolution of the
issues associated with qualifications of the unlisted component.
Manufacturers are the best source of information. If the manufacturer's
documentation is not acceptable, the owner and designer must perform the
component qualification. The rules described below for components
fabricated at LANL should be followed when Manufacturers Standards are
not acceptable. Another alternative is to select a different
manufacturer to supply components that meet B31.3 requirements.

### Components Built to Site Standards

Piping components that form part of the pressure boundary of a piping
system, that are fabricated at LANL require qualification to the
requirements of the B31.3 Code. The pressure design of these components
is specified in paragraph 304.7.2 of the Code. The Code requires that
calculations be performed to support the design of these components.
These calculations must be consistent with the design criteria of the
Code and must consider all applicable ambient and dynamic loads (ref.
paragraph. 301.4 through 301.11). The Code also requires that the
calculations be substantiated by one of the following methods:

 Extensive successful service of the component under comparable
conditions including loading, environment and fabrication of like
materials,

 Experimental stress analysis to code requirements,

 Proof testing to code requirements, or

 Detailed stress analysis to ASME B&PV Code Section VIII, Div. 2.

### Evaluation of Components for Pressure/Temperature Ratings

The preceding describes actions to meet necessary Code requirements for
unlisted components. All piping components in a B31.3 system must meet
the minimum Code requirements for design, materials, fabrication,
examination, and testing. The following guidance is provided for review
of these areas when evaluating an unlisted component.

### Design

The rules in B31.3 address the pressure design of components in
paragraph 304. The rules and equation in paragraph 304 can be applied to
simple shapes, such as cylinders and other common piping geometry.
Equations and rules for additional shapes can be found in the ASME B&PV
Code Section VIII. The design methodology in Section VIII is acceptable
for unlisted component analysis in B31.3. Additional methods used to
evaluate unlisted components include the use of equations in "Roark's
Formulas for Stress and Strain". The use of all these equations requires
that the components be idealized into bounding shapes for which the
equation is valid. Manufacturers generally use simple shapes in the
design of components, to minimize fabrication costs.

Design qualification of unlisted components can also be accomplished by
comparison to listed components with established pressure/temperature
ratings. The comparison involves a review of the wall thicknesses and
geometry to demonstrate that the unlisted component is bounded by a
component with an established pressure rating.

### Material

Typically, unlisted components are fabricated from B31.3 listed
materials. However, when the materials are not listed by the Code, the
material must be qualified in accordance with the requirements of the
Code. Reviewing the material of an unlisted component is done to ensure
a specified minimum allowable stress at the design temperature. The
sources for allowable stress values include the ASME B31 Codes of
Pressure Piping and the ASME B&PV Code Section II. B&PV Code Cases
should also be reviewed for allowable stresses for specific materials.
The material should also be reviewed for susceptibility to degradation
mechanisms associated with the service conditions, including a review of
brittle fracture.

### Fabrication

The processes used to fabricate unlisted components must also be
reviewed for Code compliance. Some fabrication processes can cause gross
or local wall thinning. If wall thinning is possible, thinning should be
accounted for when the nominal thickness is specified. Additional
fabrication allowances should be added to the required thickness to
account for manufacturing processes. Examples of wall thinning include
the 12½% mill tolerance that is applied to all piping and the allowances
for wall thinning due to pipe bending and threading. If welding is used,
the welders and welding procedure must be qualified to ASME Section IX.
If bolting is used, torquing procedures should be consistent with
Appendix E.

### Examinations

Unlisted components fabricated at LANL must be examined in accordance
with the Code. Components that are mass-produced to manufacturer's
standards may have statistical quality control methods applied. When
components are built to manufacturer's standards that require
examinations, the standard should be reviewed to ensure that the extent
of required examination and acceptance criteria meet the Code
requirements for the specified fluid service category. When
manufacturers do not specify examination requirements, the design should
be reviewed to ensure that adequate margin (i.e., wall thickness) exists
above the minimum design requirements to address the lack of
examination. To review this aspect, the Basic Casting Quality Factors,
Table A-1A of B31.3, the Basic Quality Factors for Longitudinal Weld
Joints, Table A-1B, and the Joint Efficiencies, UW-12 B&PV Section VIII,
can be used as guidance in determining an adequate wall thickness for
castings or components joined by welding.

### Testing

The B31.3 Code requires leak testing for all components. This test does
not assess the structural integrity of the components. The Code leak
test is performed at pressure levels that do not challenge the ultimate
strength required by the Code. In most cases the component is subjected
to the leak test after being installed in the field. All components
should be reviewed to insure that their pressure/temperature rating is
acceptable for the test conditions.

Some components will be qualified using a structural integrity test. The
B31.3 Code accepts proof tests in accordance with the ASME B16.9, MSS
SP-97, and ASME B&PV Section VIII Division 1, UG-101. When components
are qualified by proof test, the factor of safety between failure and
the pressure rating should be as specified in the Code to which the
component was tested. When a factor of safety is not specified, margins
against failure that ensure safety equal to or superior to the intent of
the ASME B31.3 Code must be applied.

### Instruments

Instruments are not in the scope of ASME B31.3. The Code defines the
boundary to include all piping (tubing) and components used to connect
instruments to other piping or equipment, but specifically excludes
instruments. Instruments are usually purchased as pressure rated
components. When evaluating instruments for use in pressure piping
systems, the requirements of DOE Order 440.1A must be considered. This
order states "When National Consensus Codes are not applicable (because
of pressure range, vessel geometry, uses of special materials, etc.),
implement measures to provide equivalent protection and ensure safety
equal to or superior to the intent of the ASME Code."

When evaluating instruments the designer should ensure that the
instruments are selected to meet the requirements of the fluid service.
Specifically, the instrument's pressure/temperature rating must be equal
to or exceed the design pressure and design temperature of the system.
The attachment of the instrument to the piping system must meet the
requirements of B31.3. When instruments are fabricated from piping
components (e.g., flanges and spool pieces), the piping components must
meet the requirements of B31.3.

### Other Loads

The design equations and rules in the B31.3 Code only address the
pressure loading of components. Components must be designed for all
applicable loads expected during the design life of the component. See
paragraph 301 "Design Condition" of B31.3 for a listing of loads to be
considered. At LANL, ESM Structural Chapter should be used to specify
NPH loading.

## 302.3.5 Limits of Calculated Stresses due to Sustained Loads and Displacement Strains

Stress Analysis, for loading other than pressure, per ASME B31.1 is
acceptable and recommended. When the B31.1 Code is used for the stress
analysis, Paragraph 104.8 shall be used in its entirety. Appendix I
provides guidance for stress analysis of piping systems.

## 302.3.5(c) Longitudinal Stresses S~L~

The longitudinal stress SL due to deadweight only can be kept within
approximately 2300 psi if vertical hangers are spaced as shown in Table
2 (from ASME B31.1).

+-----------------------+-----------------------+-----------------------+

Notes:

1)  Maximum spacing between vertical pipe supports for horizontal
    straight runs of standard and heavier pipe at maximum operating
    temperature of 750°F.

```{=html}
<!-- -->
```
13) Does not apply where span calculations are made or where there are
    concentrated loads between supports, such as flanges, valves,
    specialties, etc.

14) The spacing is based on a fixed beam support with a bending stress
    not exceeding 2300 psi and insulated pipe filled with water or the
    equivalent weight of steel pipe for steam, gas, or air service. The
    pitch of the line is such that a sag of 0.1 in between supports is
    permissible.

15) Applied only for deadweight design. Other loading conditions must be
    evaluated.

## 302.3.6 - Limits of Calculated Stresses due to Occasional Loads

For accident (faulted) conditions and one-time non-repeated anchor
motions, the allowable stress may be increased to:

S = min (3Sh, 2Sy)

Allowables (Sh) are from B31.1 which are lower than B31.3.

## 304.1.2 - Straight Pipe under Internal Pressure

For the pipe size, schedule, material and design pressure/temperature
combinations provided in the Piping Specifications, this section is met.
**If the piping specifications in Appendix A are not applied for the
pressure design, additional engineering calculations are required.**

## Mitered Segments of Pipe

Additional calculations are required for mitered joints. See Appendix M
for mitered joint evaluation methodology.

## 304.3 - Branch Connections

Additional calculations are required to determine necessary
reinforcement. See Appendix N for branch connection evaluation
methodology.

## 307 - Valves

A selection guide for valves is provided in Appendix D. This guide
provides information to aid in selection of the proper valve for the
intended fluid service.

## 308.4 - Gaskets

Appendix C provides information on gasket ratings to be used in the
selection of gaskets. Appendix B provides some information on
compatibility of gasket materials with common fluids.

## 309 - Bolting

Torque values for flanged joints are provided in Appendix E.

## 319.4 - Flexibility Analysis

Formal flexibility analysis is not necessary if:

1)  The design temperature is at or below 150°F and the piping is laid
    out with inherent flexibility

```{=html}
<!-- -->
```
16) The design temperature is at or below 250°F and the piping is
    analyzed for flexibility using simplified methods of calculation.

## 321 - Piping Support

Design of pipe supports are addressed in Standards such as Manufacturers
Standardization Society of the Valve and Fittings Industry MSS-SP-58.
Allowable stress levels for supports are provided in the AISC Manual of
Steel Construction and the AISC Standard N690. N690 is normally reserved
for safety class and safety significant systems. The ESM Structural
Chapter provides more details for applications at LANL. Guidance for the
design and modeling of piping supports is provided in Appendix I.

## 322 - Specific Piping Systems

In addition to the Code requirements, engineering practice has lead to
rules of good design practice to provide for safe and cost-effective
piping systems. The following are examples of such rules. These rules
must be applied by competent engineers in accordance with approved
procedures.

1)  Arrangement

    a.  Piping should be grouped in banks, where feasible, and allow the
        most efficient support arrangement. Piping oriented in one
        direction should be located at the same general elevation, where
        feasible.

    b.  Piping arrangement should provide space for maintenance,
        inspection and repair of components (including disassembly).

    c.  Piping arrangement should provide access to operating areas,
        corridors, observation windows, manholes and handholes.

    d.  Piping should conform to plant clearances above floor and grade.
        A minimum clearance of 7\'-6\" is desirable.

```{=html}
<!-- -->
```
17) Vents and Drains

    a.  Vents and drains should be ¾ \" or larger and as short as
        practical.

    b.  Drains from process lines should be piped to an appropriate
        collection or disposal receptacle. Drains from steam systems
        should be piped to boiler feedwater system when economically
        justified. Otherwise, they should be properly flashed and piped
        to waste.

    c.  Valves should not be installed where safety/process function of
        a piping system can be impeded (e.g. tank overflow lines, relief
        valves, vacuum breakers, etc.).

    d.  Caps are needed if the vent and drain lines require pressure
        testing.

    e.  Caps are needed if the fluid service presents a contamination
        concern.

    f.  Vents located outside without caps should be configured so that
        rainwater won't collect in the end of the piping.

    g.  Leakage through vent and drain valves on capped lines is a
        safety issue. The pressure behind the cap can be a hazard for
        the worker during removal. If the cap is only needed for
        cleanliness a small hole can be drilled in the cap or a cover
        without pressure retaining capability may be used.

18) Steam Distribution (Traps and Strainers)

    a.  Steam traps and strainers should be selected, located and sized
        by the designer. Steam trap rated capacity shall have been
        determined by manufacturer using ASME Performance Test Code PTC
        39.1.

    b.  A trap bypass should be installed only where a process requires
        uninterrupted operation and the condensate must be discharged
        into a closed system.

    c.  When a bypass is required on a bucket-type steam trap, the
        bypass valve must be placed above the trap to prevent loss of
        prime in the event of valve leakage.

    d.  End connections of traps and strainers should be the same as
        joints permitted in the design except strainer blow off
        connections and downstream piping may be threaded.

19) Buried Piping

    a.  See Appendix L for Guidance for the Design of Underground
        Process Piping Systems.

20) Pipe Hangers and Supports

    a.  Design and manufacture of standard pipe supporting elements
        (catalog items) should be per MSS-SP-58.

    b.  Design of Non-standard pipe supporting elements (beams, columns,
        welds, etc.) should be in accordance with the requirements as
        prescribed by the American Institute of Steel Construction
        standards. Unless otherwise specified, materials should be ASTM
        A36.

    c.  Painting and galvanizing are acceptable measures for corrosion
        control of piping supports. When galvanized supports are
        specified, the galvanizing should be applied in accordance with
        ASTM A123 or B633-SC4, Type 1. Coating should not be applied
        within (or should be removed from) one inch of weld areas.
        Painted or galvanized areas that have been damaged during
        installation should be recoated.

    d.  Unless otherwise indicated on design drawings or specifications,
        mislocated, punched or drilled holes should be restored by
        welding per AWS D1.1 Section 5.26.5. Mislocated holes may be
        left open or filled with bolting only with the written approval
        of the Designer.

21) Standard Pipe Sizes

    a.  The following pipe sizes (inches) are typical at LANL.

+-------------+-------------+-------------+-------------+-------------+
| ¼           | 1 ½         | 4           | 12          | 20          |
|             |             |             |             |             |
| ½           | 2           | 6           | 14          | 24          |
|             |             |             |             |             |
| ¾           | 2 ½         | 8           | 16          |             |
|             |             |             |             |             |
| 1           | 3           | 10          | 18          |             |
+-------------+-------------+-------------+-------------+-------------+

b.  Non-typical pipe sizes NPS 3/8, 1-¼ , 3- ½ , and 5 may be used for
    connections to equipment, sprinkler systems and pipe jackets.

```{=html}
<!-- -->
```
1)  Valves

    a.  The designer is responsible for assuring that selected valves
        are adequate for the service. The Designer may select alternate
        valves better suited for the service. Guidance for valve
        selection is provided in Appendix D.

```{=html}
<!-- -->
```
22) Threaded pipe nipples should be:

    a.  seamless

    b.  the same material as non-threaded pipe, and

    c.  of schedules as indicated in the Piping Specifications or by
        Design

23) Galvanizing

    a.  Galvanizing is acceptable when required for external corrosion
        protection.

    b.  Galvanizing of pipe should be per ASTM A53.

    c.  Galvanizing of flanges, unions, and fittings should be the
        hot-dip process per ASTM A153. Weld end fittings NPS 4 and
        smaller may be black and painted after welding. Flanges and Stub
        Ends that are hot dipped galvanized shall be refaced to the
        requirements of the original Design Standard following the
        galvanizing process.

    d.  Galvanizing generally is a more economical weather-resistant
        coating than sandblasting and painting for piping NPS 4 and
        smaller. When a piping system requires many welded fittings the
        cost of grinding to remove the galvanizing for weld preparation
        may be more costly than painting. Use of galvanizing as a
        protective coating should be considered only when galvanizing is
        compatible with the contents of the piping.

    e.  Support components may have a zinc electroplate coating in lieu
        of a hot dip galvanized coating. Electroplate zinc coatings are
        per ASTM B633 and should specify Service Condition (SC) 4 as the
        required thickness.

24) Gasket and Packing

    a.  The designer is responsible for assuring that the flange and
        valve gaskets and valve stem packing are adequate for the
        intended service. Guidance for the selection of gaskets for
        Fluid Service application is provided in Appendix B.

25) Erosion/Corrosion, Radiation, and Thermal Aging

    a.  The designer must consider the effects of erosion/corrosion,
        radiation, and thermal aging during the material selection
        process.

    b.  The designer must consider practices to minimize Chloride Stress
        Corrosion Cracking (SCC) of austenitic stainless steels. See ESM
        Mechanical Point-of-Contact.

    c.  When required by the design, austenitic stainless steel and
        other corrosion resisting alloys should be evaluated for
        resistance to intergranular corrosion. See ESM Mechanical
        Point-of-Contact.

26) Piping material limitations in radiological controlled areas:

    a.  Teflon thread lubricant (tape or dispersion) should be evaluated
        for suitability by the designer (see App C).

    b.  Plastic piping materials such as gaskets, packing, valve cavity
        liners, diaphragms, etc., should be evaluated for their
        suitability for use by the designer and substitutions
        appropriately specified in project drawings or specifications.

    c.  Piping joints that use degradable materials, such as gaskets,
        thread compounds, O-rings, etc., should be evaluated for
        suitability for use by the designer and substitutions
        appropriately specified in project drawings or specifications.

27) Aluminum Piping

    a.  When aluminum piping is joined to vessels or piping systems
        constructed of other metals, and the fluid handled is an
        electrolyte, there is a tendency for aluminum at the joint to
        corrode. This is a problem where the other metals are copper or
        carbon steel. This can be prevented by eliminating the metallic
        electrical path through the joint by one of the following
        methods:

        i.  Install a plastic flanged spool piece in the line. Check the
            adequacy of the plastic spool for pressure, temperature and
            chemical compatibility with the electrolyte. This method is
            preferred and has the advantage that sludge inside the line
            will not bridge the gap from metal to metal.

        ii. Install spool pieces of heavier wall aluminum pipe (for
            increased corrosion allowance). This method is especially
            suitable where the pipe is dismantled frequently for other
            reasons.

        iii. Install insulating flange kits (insulating gaskets, bolt
             sleeves and bolt head washers). The insulating material
             must be checked for chemical compatibility with the
             electrolyte.

    b.  Aluminum pipe should be insulated from carbon steel pipe
        supporting components. Examples of insulation are 15-pound
        asphalt-impregnated felt, plastic coated pipe supports, or
        galvanized pipe supports.

    c.  Aluminum flanges are not recommended. When used they should
        conform to the Requirements of ASME B31.3 Appendix L and be flat
        faced.

    d.  Threaded connections in aluminum piping should be avoided. Where
        fit-up to threaded equipment is required use minimum length
        schedule 80 pipe with one end threaded.

    e.  Thread pipe with clean, sharp dies reserved for use on aluminum
        only. Use cutting oil suitable for aluminum.

    f.  Aluminum piping should be handled carefully to avoid embedding
        iron and copper particles, which could cause pitting corrosion
        when in contact with an electrolyte.

28) Pump Piping

    a.  For horizontal pumps with suction lift, when suction line is
        larger than inlet nozzle. The following guidance applies:

        i.  A reducer should not reduce by more than one pipe size.

        ii. For greater reduction, use a fabricated reducer with 10^0^
            maximum included angle and qualify the reducer as an
            unlisted component.

        iii. When reducers are installed in suction lines use an
             eccentric reducer with the flat side on the top.

    b.  Elbows should not be installed directly on a pump's suction
        unless the elbow is equipped with straightening vanes.

    c.  The designer should comply with the maximum allowable pump
        nozzle loads where specified by the pump manufacturer.

29) Back Siphon/Backflow

    a.  Physical connections made between domestic water system and any
        industrial piping system, vessel, or other equipment should be
        designed and installed to prevent backflow and back siphonage.
        See ESM Chapter 6 Section D20, Cross Connection Control
        subsection.

# III - MATERIALS

See Appendix C for general guidance for materials selection.

See Appendix O for additional material requirements for Safety Class
Piping Systems.

Fluid Service Sheets are provided in Appendix B to provide guidance on
the selection of material for compatibility with the specified fluid
service.

# IV -STANDARDS FOR PIPING COMPONENTS

## 326 - Dimensions and Ratings of Components

ASME B31.3 Table 326.1 (also A326.1 and K326.1) identifies component
standards that are "listed." Unlisted components (components made to
standards or specifications not identified in Table 326.1) must be
qualified per ASME B31.3 paragraphs 302.2.3 and 304. Proof of
qualification is the responsibility of the Owner (LANL Design Authority)
or Designer (See Paragraph 302.2 of this Guide).

A component to be used in a Code application must be listed in the Code
and marked to Code requirements. Marking requirements for common
components are provided in Appendix G.

# V - FABRICATION, ASSEMBLY AND ERECTION

## 328 - Welding

Welding requirements of B31.3 are met by following the requirements
identified in the LANL Welding Manuals (Future).

## 328.5.2 - Fillet Weld

The minimum fillet weld sizes required by B31.1 and B31.3 for slip-on
flange and socket weld connections are listed in Appendix J.

## 332 - Bending

1)  The following guidance is provided for bending:

    a.  Hot bending of piping should be performed in accordance with
        written procedures. Hot bending of austenitic stainless steels
        should be followed by a full solution anneal in accordance with
        written procedures.

    b.  No bending should be performed at metal temperatures less than
        40°F.

    c.  Cold bending may be performed using hydraulic or mechanical
        bending machines. Bending machines should be qualified by test
        for pipe minimum wall and ovality.

    d.  Mandrel and die used in bending stainless steel piping should be
        free of zinc.

    e.  Pipe longitudinal welds should not be located within 30 degrees
        of the plane of bend measured axially from the pipe centerline.

    f.  Necking as determined by reduction of the outside circumference
        should not exceed 4%.

    g.  Creased or corrugated bends are not permitted.

    h.  After bending, the finished surface should be free of cracks and
        substantially free from buckling, by visual inspection. Depth of
        wrinkles on the inside of the bend as determined from crest to
        trough should not exceed 1.5% of the nominal pipe size.

    i.  Flattening or ovality of a bend, the difference between maximum
        and minimum diameters at any cross section, should not exceed 8%
        of nominal outside diameter for internal pressure and 3% for
        external pressure.

    j.  Wall thinning in piping shall not exceed:

        i.  10% - Bend radius of 5 pipe diameters and larger

        ii. 21% - Bend radius of 3 pipe diameters.

    k.  Wall thinning in tubing shall not exceed:

        i.  12% - Bend radius of 5 pipe diameters

        ii. 22% - Bend radius of 3 pipe diameters

        iii. 37% - Bend radius of 1.5 pipe diameters

```{=html}
<!-- -->
```
30) Tube bending differs from pipe bending in that it is usually
    performed in the field with a manually operated bender. The
    following guidance is provided to ensure good results on each bend.

    a.  Measure and mark exactly, then insert tube in bender.

    b.  Always attempt to bend in the same direction. If backbending, be
        sure to compensate for tubing stretch or pickup.

    c.  Clamp tubing securely in bender.

    d.  Check to make certain that the length mark is tangent to the
        desired angle on the radius block or in line with the desired
        degree on the link member.

    e.  Bend accurately to the desired angle plus springback allowance.

    f.  Remove tube and check bend angle and measurement length.

## 335 - Assembly and Erection

1)  For tolerances on fabrication, refer to the Pipe Fabrication
    Institute Standard ES-3, \"Fabrication Tolerances\".

```{=html}
<!-- -->
```
31) Typical tolerances for erection (field installation) are the larger
    of 6\" or D/2 for safety related piping and 12\" or D for non-safety
    related piping, while maintaining code, design and vendor alignment
    and slope requirements. Tolerance must not affect the sequential
    location of components, and fittings.

32) The following general requirements apply to buried pipe:

    a.  For installation of buried process piping refer to Appendix L.

    b.  Permits from the New Mexico Environment Department and
        environmental impact reports for the DOE may be required.

    c.  Bedding material should be granular, well graded and capable of
        being compacted flat

    d.  Backfill or fill material should contain no rocks and stones
        larger than 3 inch in the greatest dimension and should be free
        of frozen lumps, vegetable matter, trash, chunks or highly
        plastic clay or other unsatisfactory matter.

    e.  As an option, Controlled Low Strength Material (CLSM or
        "flowable fill") may be substituted for bedding material,
        embedment material or backfill material.

    f.  Prior to excavation, the existing underground structures and/or
        utilities should be located.

    g.  Where the trench bottom is unstable or contains unsuitable
        material, this material should be excavated to a minimum depth
        of 6\". The excavated material should then be replaced with
        suitable material, or CLSM.

    h.  Compaction testing of bedding (excluding CLSM materials) should
        be done at frequencies specified by design in any location
        specified by the cognizant inspection authority. Bedding
        sections failing to meet these specifications shall be removed
        and replaced, or reworked.

    i.  The minimum depth of cover shall be 30" (top of pipe to finished
        grade).

    j.  The minimum slope or grade indicated on design documents shall
        be maintained regardless of other installation tolerance.

    k.  The use of vertical installation tolerance shall not increase
        unvented high points unless these are explicitly approved.

    l.  Upon completion of installation, record the as-installed piping
        geometry to within the tolerance as shown below:

        i.  Vertical plane = [+]{.underline} 1\"

        ii. Horizontal plane = [+]{.underline} 3\"

## 335.1.1(a) - Alignment (Piping Distortions)

Allowable misalignment and fit-up tolerances are provided in Appendix F.

## 335.1.1(c) - Alignment (Flanged Joints)

The allowable flange gaps per B31.3 are provided in Appendix E.
Allowable flange rotations above those provided in the Code are provided
in Appendix F.

## 335.2 - Flanged Joints 

Refer to Appendix E for guidance on the proper installation of flanged
connections.

## 335.3 - Threaded Joints

1)  Threaded components and threaded ends are examined before assembly
    for cleanliness and continuity of threads and are in conformance
    with applicable standards.

```{=html}
<!-- -->
```
33) Compound or lubricant used on threads is suitable for the service
    conditions and shall not react unfavorably with either the service
    fluid or the piping material.

34) Threaded joints to be seal welded are made up without thread
    compound or lubricants.

35) When design requires threaded piping to be seal welded, seal welds
    shall cover all exposed threads.

36) Installation of threaded joints involves the cutting of threads and
    assembly of the joint. Cutting threads with a hand threader involves
    the following steps. Threads may also be cut with a power threader.

    a.  Select the proper size of die.

    b.  Clean surface of pipe. Be sure the end is square and free of
        burrs. Tapering the end of pipe is helpful starting the dies.

    c.  Mount the threader on the pipe making sure that the taper is
        headed in the forward direction.

    d.  Use thread cutting oil.

    e.  Pressure should be applied to start dies on pipe.

    f.  The thread length is correct when the outer surface of die is
        even with the end of the pipe.

    g.  Remove die and clean threads with brush or rag.

    h.  Apply joint compound or tape that has been approved by the
        Facility for the application.

    i.  Hand tighten fitting, then tighten to required degree of
        tightness with correct wrench.

## 335.6. -(a) Expanded Joints and Special Joints

Special precautions should be taken for any piping system containing an
expansion joint assembly.

1)  The manufacturer\'s and/or designer\'s special installation
    instructions shall be followed.

```{=html}
<!-- -->
```
37) Expansion joint assemblies should be carefully unpacked and erected
    to avoid mechanical damage to the assemblies while handling or
    rigging. Erection straps or chains shall not be loaded against or
    connected to bellows elements, covers or any assembly hardware
    during erection.

38) Prior to connecting or installing an expansion joint assembly, the
    erector should inspect the assembly to insure that all
    factory-installed shipping bars, brackets or other locking devices
    are in place. No modification to or removal of these devices shall
    be permitted until after the piping system closures are completed.

39) The expansion joint assembly may be equipped with permanent tie rods
    or limit rods, which are necessary for the functional operation of
    the joint assembly. Where provided, these rods shall not be removed,
    nor their factory set lengths and clearances modified, without
    approval by the designer.

40) An expansion joint assembly shall not be exposed to hydrostatic test
    or pressure flushing operations until all permanent anchors, guides
    and restraints are installed on the piping system. Hydrostatic test
    or flushing pressure shall not be greater than the manufacturer\'s
    recommended test pressure. All temporary shipping bars or brackets
    should be removed prior to system pressurization.

## 335.6. - (b) Special Joint - Compression Fittings

Specialty fittings are considered as unlisted component but are
acceptable for use where identified in the attached Piping
Specifications. The following guidance is essential for the proper
installation and maintenance of compression fittings. The following
instructions are applicable to Swagelok and Parker fittings.

1)  Ends must be cut square. The preferred method of cutting tubing is
    by hacksaw with suitable guide for squareness. Tube cutters should
    not be used for stainless steel due to work hardening.

```{=html}
<!-- -->
```
41) Burrs must be removed inside and outside for proper entry into
    fitting and to prevent system contamination and or restricted flow.

42) Tube ends must be clean. Remove all filings, chips, and grit before
    attachment of fittings.

43) Tube line fabrication (bend angles and measured lengths) must be
    accurate so that the tube end easily enters the fitting in proper
    alignment. Do not force an improperly fitted tube line into the
    fittings.

44) The tube end must be bottomed against the shoulder in the fitting
    body. This is necessary to prevent movement of the tube while the
    nut forces the ferrule to grip the tube, and to seal through any
    imperfections that may exist on the outside tube surface.

45) Never permit the fitting body to rotate during tube end make-up.
    ***Two wrenches must be used***. Assemble port connectors to
    components first and hold with wrench while making up the tube
    joint. All types of union bodies must be held while each of the tube
    ends is made up.

46) Never attempt to make up by torque or feel. Always turn the nut the
    prescribed amount (listed below) regardless of the torque required.

Sizes 1/16" - 3/16" ¾ of a turn from finger tight

Sizes ¼ "- 1" 1 ¼ turns from finger tight

Note: Fitting end plugs require only ¼ " turn from finger tight make up
in all sizes.

## 335.6. -(c) Remaking an Existing Joint 

Remaking an existing joint is as important as the initial installation.
The following instructions are provided for the remake of these joints.

1)  A disassembled joint can be remade simply by retightening the nut to
    the position of the original make-up. For maximum number of remakes,
    mark the fitting and nut before disassembly.

```{=html}
<!-- -->
```
47) Before retightening, make sure the components are clean and that the
    assembly has been inserted into the fitting until the ferrule(s)
    seats in the fitting.

48) Retighten the nut by hand. Rotate the nut with a wrench to the
    original position as indicated by the previous marks lining up. A
    noticeable increase in mechanical resistance will be felt indicating
    the ferrule is being re-sprung into sealing position. Then snug the
    nut 1/12 turn (½ hex flat) past the original position.

49) Check ferrule orientation when applicable.

50) Use gap gage when applicable.

# VI - INSPECTION, EXAMINATION AND TESTING

## 340.4- Qualification of the Owner's Inspectors

Qualification of individuals performing the Owner's Inspector Function
shall meet the requirements of this paragraph. Owner's Inspectors are
designated by the Site Chief Engineer. Refer to the IFMP Training and
Qualification Program ACP-T&Q-01 (future).

## 341.4 - Extent of Required Examination

\"Examination\" is not limited to welds. Records, materials,
fabrication, erection pressure testing, as-built, must also be examined
as specified by Code. Refer to Table 3 for a list of examination
attributes and the extent of required examination.

Guidance of specific examinations other than welds is provided below.
This is not intended to be an all-inclusive list of items to be
examined.

### Material

1)  At point of installation, materials and components are sufficiently
    identified by markings, tags, or documentation to assure they are in
    accordance with the specified requirements and traceable to the
    required documentation.

### Fabrication

1)  After bending, the finished surface should be free of cracks and
    substantially free from buckling, by visual inspection. Depth of
    wrinkles on the inside of the bend as determined from crest to
    trough should not exceed 1.5% of the nominal pipe size.

```{=html}
<!-- -->
```
51) Thinning of wall thickness after bending and forming of pipe does
    not exceed the following: 10% for bend radii of greater than or
    equal to 5 pipe diameters, or 21% for bend radii of less than or
    equal to 3 pipe diameters.

52) Thinning of wall thickness after bending and forming of tube does
    not exceed the following: 12% for bend radii of greater than or
    equal to 5 pipe diameters, 22% for bend radii of less than or equal
    to 3 pipe diameters, or 37% for bend radii of less than or equal to
    3 pipe diameters.

53) Necking down after bending and forming as determined by reduction of
    the outside circumference does not exceed 4%.

54) Flattening or ovality of a bend, the difference between maximum and
    minimum diameters at any cross section, does not exceed 8% of
    nominal outside diameter for internal pressure and 3% for external
    pressure.

55) Cold bending is done at a temperature below the transformation
    range.

56) No pipe bending is performed at metal temperatures less than 40^0^F.

57) Hot bending is performed to a design approved procedure.

58) Longitudinal weldments are not located within 30 degrees of the
    plane of bend.

59) Welding examinations are per the LANL Welding Manuals (future).

### Fabrication of Longitudinal Welds

1)  Perform radiography for longitudinal groove welds required to have a
    weld joint factor E~i~ equal to or greater than 0.90.

### Mechanical Joints

1)  Threads in the bolts and nuts to be free from nicks, burrs, grit,
    chips, and dirt and well lubricated prior to makeup.

```{=html}
<!-- -->
```
60) Bolts extend completely through their nuts.

61) Manufacturer's and designer's installation instructions for
    expansion joints has been followed, and all factory installed
    shipping bars, brackets, or other locking devices are in place and
    remain in place until after piping system closures are complete.

62) Any damage to the gasket seating surface which would prevent gasket
    seating has been repaired, or the flange replaced. Refer to Appendix
    E.

63) The nuts have been tightened in a staggered crisscross pattern and
    in increments of not more than 1/3 the total required torque.

64) No more than one gasket is used between contact faces in assembling
    a flanged joint.

65) Galvanized flanges must be refaced with the appropriate surface
    finish after galvanizing in complete.

66) Prior to bolt up, flange faces are aligned within 1/16" in./ft.
    (0.5%) measured across any diameter and flange bolt holes are
    aligned within 1/8" maximum offset. Refer to Appendix F for guidance
    on misalignment fit-up tolerance.

67) Sealing surfaces of the flare of flared tubing joints are examined
    for imperfections before assembly.

68) Where the manufacturer's instructions call for a specified number of
    turns of the nut, these shall be counted form the point at which the
    nut becomes finger tight.

69) Threaded components are examined before assembly for cleanliness and
    continuity of threads and for conformance of threads with applicable
    standards.

70) Compound or lubricant used on threads (for components and bolts) is
    suitable for the service conditions and shall not react unfavorably
    with either the service fluid or the piping material.

71) Threaded joints to be seal welded are made up without thread
    compound or lubricant.

72) When design requires threaded piping to be seal welded, seal welds
    shall cover all exposed threads.

### Erection

1)  Piping is not distorted to bring it into alignment for joint
    assembly.

```{=html}
<!-- -->
```
73) Wedges are not being used to laterally contain or position pipe for
    closure fit-ups.

74) The amount and direction of cold spring, (defined as the intentional
    deformation of piping during assembly to produce a desired initial
    displacement and stress) is in accordance with the design values.

75) Support locations, type, and restraint direction are as specified in
    the design drawing.

76) Pipe slope has been maintained in the direction specified by the
    slope arrow and/or work point elevation indicated on the design
    drawing.

77) Changes in piping elevation have not impacted slope requirements,
    high point vents, or low point drains.

78) Upon completion of installation the as-installed piping geometry has
    been recorded on the design documents. Typical tolerances for
    erection (field installation) are the larger of 6" or D/2 for
    safety-related piping or 12" or D/2 for non-safety related piping,
    while maintaining code, design and vendor alignment and slope
    requirements. Tolerance must not affect the sequential location of
    components and fittings, or the centerline lengths.

79) Valves and other components are oriented as shown in design
    documents or manufacturer's requirements.

80) Insulation is installed as specified.

81) There are no visible defects, missing or damaged parts in piping,
    components, or piping supports.

### Complete System Meets Design

1)  Examination of erected piping for evidence of defects that would
    require repair or replacement, and for other evident deviation from
    the intent of the design.

```{=html}
<!-- -->
```
82) Any additional requirements supplementing the Code as specified by
    the design.

83) Cleanliness of piping is in accordance with the requirements of the
    applicable standard or as specified by design.

### Other

1)  Welding examination requirements are per the LANL Welding Manuals
    (future).

## 341.4.1(b)(1)- Other Examinations

In-process examination may be substituted for volumetric examination on
a weld-for-weld basis, if volumetric examination of a particular weld is
prohibitive. This substitution cannot be granted across the board for a
whole job.

Requirements for examinations of repairs and alterations of in-service
piping are provided in Appendix P.

## 342- Examination Personnel

Examiners shall have training and experience commensurate with the needs
of the specified examinations. The employer shall certify records of
examiners employed, showing dates and results of personnel
qualifications, and shall maintain them and make them available to the
Inspector. Examinations other than welds shall be conducted per the PS
Division requirements.

## 345 - Testing

Table 4 is a summary of the leak test requirements of B31.3. Refer to
Appendix P for testing requirements associated with Repairs,
Alterations, and Modifications.

Guidance for performing Leak/Pressure testing is provided in Appendix H.

\(1\) May be substituted for the hydrostatic or pneumatic leak tests
provided: a) The Owner has determined a hydrostatic test would damage
linings or internal insulation, or contaminate a process which would be
hazardous, corrosive, or inoperative in the presence of moisture, or
would present the danger of brittle fracture due to low metal
temperature during the test. b) The Owner has determined a pneumatic
test would present undue hazard of possible releases of energy stored in
the system, or would present the danger of brittle fracture due to low
metal temperature during the test. In either case approval of the ESM
Mechanical Point-of-Contact must be obtained.

\(2\) Additionally the piping in the installed configuration must be
tested to 110% of the design pressure.

# APPENDIX A -- PIPING SPECIFICATIONS

The attached piping specifications provide the required data to meet the
pressure design requirements of the ASME B31.3 piping code. Additional
requirements and competent engineering are required to provide a safe
and complete piping system design. Additional requirements include
material selection, functional design, system layout, component
selection, support design, thermal expansion, stress analysis,
examination and testing. These specifications must be used in
conjunction with ASME B31.3 and this Guide to ensure a sufficient piping
system design.

######## 

######## WARNING 

**Successful application of each piping specification requires the
reading and comprehension of all applicable General Notes.**

**When these guides are not applied in the pressure design of a piping
system additional calculations are required.**

The Piping Specifications are organized as follows:

100 Series Carbon Steels

200 Series Stainless Steels

300 Series High Alloy Steels

400 Series Nonferrous

500 Series Nonmetals

900 Series Non-ASME B31.3 Codes

## Required Input

The following input is required to select a piping specification. Figure
A-1 illustrates the procedure for the selection of the correct piping
specification.

### Design Code

Most of the Piping Specifications address the ASME B31.3 Piping Code.
The B31.3 Code Scope applies to the majority of process applications at
LANL. Additional ASME B31.1 and AWWA piping specifications are provided
to address applications specific to the scope of these Codes. The user
is responsible for compliance with all aspects of the design Code being
applied. This Guide addresses only B31.3, however this guidance is
typical of the requirements in other Codes.

### Fluid Service Category

The fluid service (Category D, Normal, Category M, or High Pressure) is
a term used in ASME B31.3 that considers the combination of fluid
properties, operating conditions, and other factors that establish the
basis for design of the piping system. The piping specifications were
developed to address the requirements of ASME B31.3 Normal Fluid Service
Category and/or Category D requirements. Normal Fuild Service piping
specifications may be used for Category D fluid services without
restrictions. The fluid service is indicated on each piping
specification in the design parameters section. For Category M fluid
services, and systems subjected to severe cyclic conditions, additional
restrictions apply. These additional restrictions shall be addressed by
Engineering. See Appendix M of ASME B31.3 for guidance in classifying
the fluid service category.

### Material and Corrosion Allowance

Selection of suitable piping materials to resist deterioration in
service is required to provide a safe piping design. A corrosion/erosion
allowance will need to be determined to provide the required wall
thickness. The corrosion allowance shall be specified by the letter
suffix (A, B, C, or D) in the piping specification identification (e.g.,
PS-101A). The fluid service will also affect the selection of materials
such as gaskets, valve seats and packing. Issues related to material
selection should be addressed by Engineering. Guidance for material
compatibility is provided in Appendices B and C.

### Design Pressure

The design pressure of a piping system is the pressure at the [most
severe condition]{.underline} of coincident internal or external
pressure and temperature expected during service. Examples of the design
pressure in a piping system include the deadhead pressure of a pump or
the relief valve set pressure.

The [most severe condition]{.underline} is that which results in the
greatest required component thickness and the highest component ratings.

### Design Temperature

The design temperature of a piping system is the temperature at the
[most severe condition]{.underline} of coincident pressure expected
during service.

With the above inputs, the different component options provided in the
piping specifications can be used to meet the pressure design of a
piping system. Selection of the different options provided in the piping
specification (i.e. socket-weld vs. buttweld fittings, slip-on vs. weld
neck flanges etc.) will affect the stress levels in the piping system.
Components in an existing piping system shall be replaced in kind. If
components are changed in an existing piping system these changes shall
be addressed by Engineering. For new piping system design specific
requirements for options shall be specified on the design drawings.

### Components

Piping components not provided in the piping specification can be
selected from the standards listed in ASME B31.3.

Components of higher pressure rating may be used in the piping
specification without additional analysis. All changes shall be
documented on design drawings.

### Unlisted Component Qualification

Components used in piping systems not conforming to listed standards in
B31.3 are considered unlisted by the Code and require additional
qualification.

## General Notes

**Successful application of each piping specification requires the
reading and comprehension of all applicable General Notes.**

  ---- -------------------------------------------------------------------
  1    This specification provides the necessary information to meet the
       pressure design requirements of the ASME B31.3 piping code.
       Additional requirements include, but are not limited to, support
       design, thermal expansion, material selection, examination, and
       testing. These additional requirements are addressed in ASME B31.3
       and this Guide.

  2    This specification was developed to address the requirements of
       ASME B31.3 Normal Fluid Service. This specification may be used for
       Category D fluid services without restrictions. For Category M
       fluid services, and systems subjected to severe cyclic conditions,
       additional restrictions apply. These additional restrictions shall
       be addressed by Engineering.

  3    Selections of the different options provided in this specification
       (e.g., socket-weld vs. buttweld fittings, slip-on vs. weldneck
       flanges, etc.) will affect the stress levels in the system.
       Components in an existing system shall be replaced in kind. If
       components are changed in an existing system, these changes shall
       be addressed be Engineering. For new system design, specific
       requirements for options shall be specified on the design drawings.

  4    To address the fluid service requirements of a piping system, a
       corrosion allowance will need to be determined to select the
       required wall thickness. The fluid service requirements will also
       affect the selection of materials such as gaskets, valve seats and
       packing, etc. The corrosion allowance shall be specified by the
       letter suffix in the piping specification identification (e.g.,
       PS-101A).

  5    The minimum test pressures to meet the hydrostatic test limits of
       the applicable code (i.e. ASME B31.1 or B31.3) are provided in the
       Design Parameters table in this specification for the listed design
       pressures and temperatures. Actual system design pressures should
       be used to establish hydrostatic test pressures for testing. These
       test pressures are the minimum pressure requirements to be achieved
       throughout the piping system, adjustments may be required to
       account for elevation changes in the piping system. The maximum
       test pressure provided in the design parameters is the lowest
       pressure at which the pipe size/schedule combination reaches its
       yield stress. These pressures shall not be exceeded at any location
       in the piping system. Valves, instruments, fittings and other
       components may have additional pressure limitations and may require
       isolation from the test pressure.

  6    Additional analysis is required to increase the external pressure
       rating.

  7    Components not provided in the specification can be selected from
       the standards listed in Table 326.1 of ASME B31.3. Components used
       in piping systems that are not listed in this table are considered
       unlisted by the Code and require additional qualification. See ASME
       B31.3 paragraph 304.7.2. All components must meet the
       temperature/pressure requirements.

  8    The minimum design temperature may be limited by the need for
       impact testing of material and the qualification of the welding
       procedure. The temperature limits of the fasteners may also control
       the minimum design temperature.

  9    Components with higher pressure ratings (e.g., thicker pipe or
       higher rated fittings and flanges) may be used without additional
       analysis. If such components are mixed within system, additional
       weld prep to match diameters may be required. All changes shall be
       documented on design drawings.

  10   Appendix E provides guidelines for the installation of fasteners
       and the selection of alternate fasteners. Studs are the recommended
       fasteners for connecting flanges in piping systems.

  11   Branch connections shall be made with Tees for full size and one
       size smaller branches, and for all run sizes NPS 2 and smaller.
       Welded branch connections are otherwise permitted, and shall be
       reinforced as required (see Appendix N).

  12   3D bends are permitted for pipe sizes up to NPS 6.

  13   Bends are not permitted for this piping specification.

  14   5D bends are permitted up to NPS 6.

  15   5D bends are permissible up to NPS 2.5.

  16   Piping with high corrosion rates or subject to IGSCC may require
       the use of corrosion-evaluated materials. When corrosion evaluation
       is required, this specification shall be identified as PS-number
       (A,B,C,D)-CE (e.g. PS-200A-CE).

  17   Tubing purchased to ASTM A269 shall require that CMTRs must specify
       mechanical testing to comply with ASME B31.3.

  18   Welded fittings are to be of L-Grade material only.

  19   Flange material and pressure/temperature rating shall be selected
       based on ASME B16.5 and the actual system design pressure and
       temperature.

  20   This specification was developed to address the requirements of
       ASME B31.3 Category D Fluid Service. This specification is not to
       be used for other fluid service categories

  21   Type K tubing may be substituted for Type L tubing.

  22   When hardened temper copper tubing (e.g., H temper) is used, the
       tubing shall be annealed before bending or flaring.

  23   Soldering or brazing is allowed with this tubing specification.
       Soldered joints shall be made with 95-5 Tin-Antimony solder.

  24   Qualification of the Copper Tubing in this P-Spec is based on
       properties of annealed material.

  25   This specification was developed to address the requirements of
       ASME B31.3 Normal Fluid Service, and may not be used in Category M
       fluid service

  26   Brazing of the joints is required with this tubing specification.
       The use of soft solder is not permitted.

  27   ASME B16.15, B16.18, and B16.22 fittings should be ordered 1/8 inch
       less than the tube O.D. when used with ASTM B280 tubing.

  28   Branch connections shall be made with fittings in all sizes.

  29   Piping in all Fluid Services except Category D shall be safeguarded
       per ASME B31.3.

  30   Ultraviolet inhibitor shall be specified if piping is to be used
       above ground.

  31   SDR Rated pipe per ASTM F442 is acceptable and shall be SDR 26 or
       lower. This pipe shall not be threaded.

  32   Pressure ratings for 100° F may be determined be multiplying the
       above design pressures be 0.625. For example, DR 9 pipe would be
       rated at 125 psig at 100° F (200 psig times 0.625 = 125 psig).

  33   This pipe and tube is ordered based on pressure rated diameter to
       thickness ratios (DR). To address the different Dimension Ratios
       (DRs) identified in this piping specification, the appropriate
       letter suffix shall be specified to identify which DR is required
       (e.g. PS-502F). The DRs to which the letter suffixes correspond is
       identified in the Design Parameters section of the specification
       and the Required DR Schedules are also listed in the specification.

  34   This piping specification provides the required information to meet
       the pressure design requirements of ASME B31.1 piping code.
       Additional requirements include, but are not limited to, support
       design, thermal expansion, material selection, examination, and
       testing. These additional requirements are addressed in ASME B31.1
       and this Guide.

  35   This piping specification was developed to address the requirements
       of ASME B31.1 Non Boiler External Piping. This specification may
       not be used for Boiler External Piping without additional
       restrictions.

  36   Piping components not provided in this piping specification can be
       selected from the standards listed in Table 126.1 of ASME B31.1.
       Components used in piping systems that are not listed in this table
       are considered unlisted by the Code and require additional
       qualification. See ASME B31.1 paragraph 104.7.2. All components
       must meet the temperature/pressure requirements of the system.

  37   The minimum test pressures to meet the hydrostatic test limits of
       ASME B31.1 are provided in the Design Parameters table in each
       specification for the listed design pressures and temperatures.
       Actual system design pressures should be used to establish
       hydrostatic test pressures for testing. These test pressures are
       the minimum pressure requirements to be achieved throughout the
       piping system, adjustments may be required to account for elevation
       changes in the piping system. The maximum test pressure provided in
       the schedule tables of the specification represent the pressure
       where the piping reaches its yield stress. These pressures shall
       not be exceeded at any location in the piping system. Valves,
       instruments, fittings and other components may have additional
       pressure limitations and may require isolation from the test
       pressure.

  38   Where steel pipe is threaded and used for steam service above 250
       psi or for water service above 100 psi with water temperatures
       above 220° F, the pipe shall be seamless and have a thickness at
       least equal to schedule 80 of ASME B36.10.

  39   Consult engineering for selection of fasteners in fluid services
       above 600° F.

  40   This piping specification provides the required information to meet
       the pressure design requirements of the AWWA piping. Additional
       requirements include, but are not limited to, support design,
       thermal expansion, material selection, examination, and testing.
       These additional requirements are addressed in AWWA Manual M23 "PVC
       Pipe -- Design and Installation."

  41   This piping specification was NOT developed to address the
       requirements of ASME B31.3. This specification may be used for ASME
       B31.3 service only when the additional requirements of ASME B31.3
       are addressed and implemented.

  42   The minimum test pressures to meet the hydrostatic test limits of
       AWWA M23 are provided in the Design Parameters table in each
       specification for the listed design pressures and temperatures.
       Actual system design pressures should be used to establish
       hydrostatic test pressures for testing. These test pressures are
       the minimum pressure requirements to be achieved at the source of
       pressurization. When accounting for elevation, the high point of
       the system must be subjected to at least 188 psi. The maximum test
       pressure provided in the schedule table of the specification
       represents a 10% increase above the minimum. These pressures shall
       not be exceeded at any location in the piping system. Valves,
       instruments, fittings and other components may have additional
       pressure limitations and may require isolation for the test
       pressure.

  43   Installation, examination and testing shall be per AWWA M23.

  44   Piping components not provided in this piping specification can be
       selected from the appropriate standards that meet the design
       requirements of AWWA. Components used in piping systems that are
       not listed in this table are considered unlisted be the Code and
       require additional qualification.

  45   Cast Iron mechanical joint fittings can damage PVC pipe if over
       tightened. Consult pipe manufacturer for guidance concerning
       installation of these fitting.

  46   This piping specification provides the required information to meet
       the pressure design requirements of the AWWA piping. Additional
       requirements include, but are not limited to, support design,
       thermal expansion, material selection, examination, and testing.
       These additional requirements are addressed in AWWA C600
       \"Installation of Ductile Iron Water Mains and Their
       Appurtenances\". Additionally, the required thickness of ductile
       iron pipe is dependent on the laying conditions for buried pipe.
       This should be verified by Design prior to specification of the
       pipe, and is addressed in AWWA C150 \"Thickness Design of Ductile
       Iron Pipe\".

  47   The minimum test pressures to meet the hydrostatic test limits of
       AWWA C600 are provided in the Design Parameters table for the
       listed design pressures and temperatures. Actual system design
       pressures should be used to establish hydrostatic test pressures.
       These test pressures are the minimum pressure requirements to be
       achieved at the source of pressurization. When accounting for
       elevation, the high point of the system must be subjected to at
       least 313 psi. The maximum test pressure provided in the schedule
       table on the specification represent a 25 psi increase above the
       minimum. These pressures shall not be exceeded at any location in
       the piping system. Valves, instruments, fittings and other
       components may have additional pressure limitations and may require
       isolation for the test pressure.

  48   Installation, examination and testing shall be per AWWA C600.

  49   Cement-mortar lining per AWWA C104/A21.4 is acceptable

  50   Flanges and flanged joints identified in this specification have
       bolt patterns identical to ASME B16.1 Class 125 flanges. However,
       B16.1 flanges are not rated for the design pressures allowed
       herein.

# APPENDIX B -- FLUID SERVICE sheets

This appendix contains data on selecting the appropriate materials to be
used in a specific fluid service. This data should be used with caution
because it represents cases where the chemistry of the specified fluid
is well understood. The recommendations made in the Fluid Service Sheets
are one option based on economic and technical considerations. Other
options may be technically acceptable. Questions about corrosion
allowance values for a specific fluid service should be directed to ESM
Mechanical Point-of-Contact. An index to the Fluid Service Sheets is
provided below.

  2\)   See Appendix C for Pressure-Temperature Rating of Gaskets.

  3\)   To ensure purity of DI water for chemical metallurgical research, all
        wetted parts of the piping system, including components, must be
        non-metallic. The use of non-metallic valves would require the
        qualification of unlisted components.

be based on owner preference

# APPENDIX C -- Materials Selection

This appendix contains information on selecting gaskets and materials
for pipe, fittings, valve bodies, and packing. There are many factors
that influence the proper selection of a material. These factors include
the pressure/temperature rating of the piping system and gasket material
compatibility with the fluid service. The following general guidance is
provided for material selection.

The following information provides a general description of some common
materials and the service where they might be used. This information is
not definitive or all-inclusive. For severe fluid services, additional
research on material acceptability is required, and in all cases the
final responsibility of material selection resides with the cognizant
engineering organization.

## Gaskets

The gaskets listed in Table 1 are the most commonly used gasket
materials at the LANL. Other gasket materials are used in special
applications. The use of these other gasket materials is acceptable when
properly rated for pressure, temperature and compatibility with the
fluid service.

Gaskets must be able to:

a.  Maintain integrity during handling and installation.

b.  Be sufficiently deformable to flow into imperfections on the seating
    surfaces to create an initial seal.

c.  Have sufficient strength to resist crushing under the applied load
    and defy rupture under pressure.

d.  Chemically resist fluid under all temperatures and pressures.

e.  Be strong enough to maintain the seal, tough enough to withstand
    creep relaxation, and resilient enough to provide recovery during
    normal operation including thermal cycling and vibration.

f.  Never promote corrosion of the seating surface.

g.  Be impermeable to the fluid being handled.

h.  Be sufficiently resistant to radiation, if present, to perform its
    function.

Guidance for selection of gaskets in specific fluid services is provided
in Appendix B "Fluid Service Sheets."

Refer to Table 1 for the pressure/temperature rating of some commonly
used gasket materials. Refer to Appendix E for torquing requirements.

  ------------------------------ ------------ --------------- --------------- ----------

## General Notes:

A.  Non-Spiral Wound Gaskets should be specified in thicknesses of
    either 1/16" or 1/8". The thinner (1/16") is preferred.

B.  Pressure and temperature ratings are generic based on available
    manufacturer's data. Refer to the Garlock catalog, the Lamons
    catalog, and the Flexitallic catalog. Specific ratings for these and
    other company products may vary, and cautions should be exercised
    when specifying gaskets close to the limiting conditions. Gaskets
    with pressure and temperature ratings higher than those identified
    above are available, and should be specified on a case-by-case
    basis. Other gasket materials may be available and more suitable for
    some services. The ESM Mechanical Point-of-Contact can provide
    information to the specifying engineer in some cases.

C.  Virgin Teflon material exhibits poor cold flow and creep properties
    for gaskets, and the use of gaskets made from un-reinforced Teflon
    should be avoided. Reinforced Teflon is a Teflon material in which
    some fiber, weave, braid, etc. is mixed or sandwiched in the Teflon
    to provide better strength and cold flow properties.

D.  Effects of ionizing radiation must be considered in radioactive
    services or environments.

```{=html}
<!-- -->
```
a.  A general rule for elastomers used for sealing is that an
    accumulated radiation dose of 10^6^ rads represents the point at
    which elastomers may be losing their ability to maintain a seal,
    particularly in a dynamic application where resiliency is required.
    Radioactive gas (e.g., tritium) that can diffuse into seal materials
    can accelerate damage rates.

```{=html}
<!-- -->
```
a.  Materials containing polytetrafluoroethylene (PTFE) or trade name
    Teflon^TM^ have significantly lower thresholds to radiation damage.
    A dosage of 1.7 x 10^4^ rads causes substantial damage. Common trade
    and commercial names of PTFE-like materials include: Algoflon,
    Duroid, Fluon, Fluorocomp, Gortex, Halon TFE, Kalrez
    perfluoroelastomer, Kel-F polychlorotrifluoroethylene, Neoflon,
    Polycomp, Polyflon and Teflon.

b.  When radiation exposure can be adequately predicted and controlled
    below threshold damage levels, select a polymer based on expected
    environmental conditions including dose. Polymers with relatively
    higher radiation resistance include Vespel polyimide,
    Ultra-High-Molecular-Weight Polyethylene (UHMWPE), Ethylene
    Propylene Diene Monomer (EPDM), and PEEK (Polyetheretheracetone).

## Specific Notes:

1)  Graphite gasket material may be suitable for much higher pressures
    and temperatures depending on the specific fluid service (i.e.
    chemical properties of the service fluid). Consult the ESM
    Mechanical Point-of-Contact for specifics.

```{=html}
<!-- -->
```
1)  Reinforced Teflon may be suitable for higher pressures and/or lower
    temperatures depending on the formulation of the Teflon and the
    reinforcement material used.

2)  Use of aramid fiber gasketing should be avoided in steam service.

3)  Metal reinforced Teflon is limited to 392°F.

4)  PTFE and RTFE shall not be used in High Level Waste Transfer Systems
    or similar system in which high dose will damage the material and
    changeout is difficult.

## General Guidance - Non-metals

The following is a brief description of some of the common types of
seating and packing materials, and their general use.

### PTFE

Virgin Teflon polymer. PTFE has good temperature, chemical, and
anti-friction properties. It is inert to most chemical attack, but is
affected by liquid alkalis, fluorine, and radiation. It can cold flow
under high stress. Maximum 1 x 10^4^ RADS lifetime dose. PTFE shall not
be used in High Level Waste Transfer Systems.

### RTFE

Reinforced Teflon - PTFE reinforced with added fillers, usually
fiberglass. The filler provides a higher resistance to cold flow, and
allows larger application range. There is a slight increase in friction.
Maximum 1 x 10^4^ RADS lifetime dose. RTFE shall not be used in High
Level Waste Transfer Systems.

### UHMWP

Ultra High Molecular Weight Polyethylene. UHMWP is a thermoplastic
polymer with exceptionally high notched impact strength, and resistance
to stress cracking and abrasion. It has good resistance to most
chemicals, but is not recommended for strong acids and organic solvents.
It offers higher resistance to radiation than PTFE. Maximum 2 x 10^7^
RADS lifetime dose.

### TEFZEL

TEFZEL fluoropolymer is a thermoplastic in the same family as PTFE, but
is more radiation resistant. Maximum 2 x 10^7^ RADS lifetime dose.

### PEEK

Polyetheretherketone offers increased steam handling capabilities, and
have generally higher the temperature ratings. It has good corrosion
resistance, and excellent resistance to radiation. Maximum 1 x 10^9^
RADS lifetime dose.

### FEP

A melt-processable PTFE with essentially those same properties.

### DELRIN

DELRIN is another polymer that is used at higher pressures, and also has
higher resistance to radiation than PTFE. Maximum 1 x 10^6^ RADS
lifetime dose.

### Nitrile (NBR, Buna-N)

Used for low aromatic petroleum solvents, fuels and oils, water, air,
and inactive gases.

### Viton

Used in high aromatic and halogenated solvents and fuels. Also used in
low pressure steam and strong mineral acids.

### EPDM

Used for resistance to ozone, weathering, and heat. It has poor
resistance to oils, hydrocarbons, alcohols, and radiation.

## General Guidance - Metals

The following is a brief description of some of the common metals used
in valve construction, and their general use.

### Cast Irons

Generally used in low hazard services (e.g. water or oil). Cast irons
have a low cost and are readily available. Disadvantages - no weld end
valves, generally poor corrosion resistance, and code limitations.

### Bronze

Generally used in low hazard services (e.g. water or oil). Bronze alloys
have a low cost and are readily available. They can have better
corrosion resistance than Carbon Steel in some water services.
Disadvantages - limited welding.

### Carbon Steel

Carbon steels are the standard selection for many services where
corrosion resistance is not critical. It has a relatively low cost and
is readily available. Disadvantages - generally poor corrosion
resistance.

### Type 304(L) 

SS Austenitic stainless steels are used for their high resistance to
oxidation and sulfidation, and where general resistance to corrosion is
desired. They are also used widely for cryogenic services.
Disadvantages - susceptibility to certain specific corrosion processes
(e.g. stress corrosion cracking and intergranular corrosion) in certain
media. Type 304(L) is generally a special order valve material, and has
been replaced as the "standard" stainless steel material with type
316(L).

### Type 316(L) 

SS Austenitic stainless steels are used for their high resistance to
oxidation and sulfidation, and where general resistance to corrosion is
desired. They are also used widely for cryogenic services. Type 316(L)
has a better resistance to attack by reducing agents, and lower
susceptibility to pitting than type 304(L). Disadvantages -
susceptibility to certain specific corrosion processes (e.g. stress
corrosion cracking and intergranular corrosion) in certain media.

### Alloy 20

Alloy 20 was developed to provide resistance to sulfuric acid over a
wide range of concentrations and temperatures. It has good corrosion
resistance to other media as well, and is widely used for handling
caustic soda, organic acids, chlorinated hydrocarbons, sludge acids,
etc. Disadvantage \-- cost.

### Monel

Monel provides excellent resistance to sea water, and good resistance to
aqueous sulfide and caustic. It is resistant to chloride stress
corrosion cracking. It is widely used for handling alkalis, salt water,
organic intermediates, and many air-free acids. Disadvantages \-- poor
resistance to sulfidation above 400°F, and embrittled by sulfur and
heavy metals at low concentrations during welding or heating. Corroded
rapidly by ammonia and compounds.

### Inconel

Inconel is generally used for handling corrosive media at elevated
temperatures. It provides good general corrosion and oxidation
resistance, good elevated temperature strength, good resistance to
chloride stress corrosion cracking, and excellent corrosion resistance
to caustic. Disadvantages - poor sulfidation resistance above 1000°F
creates working and welding problems, vulnerable to sensitization and
intergranular cracking in some services, and cost.

### Hastelloy B/B2 

Hastelloy B provides good resistance to reducing atmospheres at elevated
temperatures, and is very resistant to stress corrosion cracking. It is
also used for handling hydrochloric acid vapor and varied concentrations
of hot sulfuric, hydrochloric, and phosphoric acids. Disadvantages -
cost, availability, sensitizes, and can be vulnerable to intergranular
corrosion in many services.

### Hastelloy C/C276

Hastalloy C provides good resistance to hypo-chlorites and other
solutions containing free chlorine in considerable concentrations. It is
also used for handling both oxidizing and reducing chemicals, and is
very resistant to stress corrosion cracking.
Disadvantages--cost,availability.

# APPENDIX D -- VALVE SELECTION GUIDE

## Introduction

This Appendix addresses proper selection and specification of manual
valves and check valves for use in ASME B31.3 systems. This information
may be used for guidance in the selection of valves for use in services
covered by other piping codes at the discretion of the cognizant
engineer. This Appendix does not give absolute direction for the
selection of specific valves for specific services. Final selection of a
valve and determination of acceptability must be made by the appropriate
engineering organization.

Initial selection of valves for any process or service is an engineering
decision. Consideration should be given to the required materials of
manufacture (body, seats, stem, packing, etc.), type of valve required,
fluid sealing requirements, flow throttling requirements, potential
transient concerns, etc. Selection of different types of valves can
result in extremely different system response to valve action.

## Required National Codes/Standards Conformance

When used in ASME B31.3 systems, valves are required to be manufactured
and tested in accordance with listed standards or they must be qualified
as "unlisted" components. Other national consensus standards for piping
systems have similar requirements. Table D-1 identifies the standards
related to valve manufacture that are accepted as "listed" standards for
use in ASME B31.3 systems. Valves that do not conform to one of these
standards may be used provided that the ASME B31.3 requirements for
qualification of unlisted components is met (refer to paragraph 304.7.2
of ASME B31.3).

## Selection of Valve Type

One of the principal decisions in valve selection is valve type.
Selection of the proper valve type should be based on service experience
that demonstrates a particular valve type performs well in a particular
service. Manufacturers and operating facilities are good sources of
information in this respect. Some general guidance for selection of
valve type is provided herein, and is available from various reference
materials. Table D-2 provides some general service descriptions and the
type of valve commonly selected for those services as indicated in
Reference Lyons. Table D-3 provides similar information as identified in
Reference Zappe. This information should not be viewed as absolute, nor
is it intended to exclude certain types of valves from any services.
Decisions of this nature are left to the cognizant engineer.
Manufacturer's recommendations may be very helpful in this regard as
well.

Additional information on some of the more common valve types is
provided in the following paragraphs. Typical applications and some
common problems that may be helpful in the selection of the proper valve
are discussed, as well as a brief description of some common valve
types. Other valve types such as pinch valves, and diaphragm valves are
less common, and thus not described. However, these types of valves may
be selected at the discretion of the cognizant engineer.

## Gate Valves

![](media/image2.png){width="1.4083333333333334in" height="2.525in"}Gate
valves are the most common type of valve used in industrial
applications. It functions by inserting a disc across the flow path.
Gate valves may be used in systems where flow direction varies and can
be reversed as this valve type is "bi-directional," i.e. valve operation
and flow characteristics are the same for either direction of flow. Gate
valves should be used in the wide open or fully closed position only, as
this valve type is usually not suitable for throttling service. Having
very little resistance to flow, it is ideal for conditions where the
pressure drop is critical.

Some examples of available disc designs for gate valves are shown in the
following figure. All of the disc designs are used for the same type
services, except that the solid wedge disc designs are not suited for
applications with large variations in temperatures. Note that the
"double disc" gate valve is sometimes referred to as a "split disc" gate
valve.

![](media/image3.png){width="4.778472222222222in"
height="1.7020833333333334in"}

Some of the disadvantages of a gate valve are as follows:

1)  The full stem travel requires many turns of a handwheel and many
    more turns when fitted with gearing.

```{=html}
<!-- -->
```
5)  Due to the long stroke and the outside appurtenances necessary to
    accommodate this stroke, a longer space envelope (over-all length)
    is required.

6)  Body seat surfaces for gate valves are more difficult to machine or
    refinish.

7)  Very little or slow movement of the disc near the full closed
    position causes high velocity flow, resulting in galling of the
    sliding parts and scoring of the seating surfaces (often called
    "wire drawing").

8)  Solid wedge type gate valves have a generic problem called "thermal
    binding." This condition occurs when a valve is closed tightly while
    the high temperature system it is located in is still in operation.
    Subsequently, the system is shut down, and cooldown takes place.
    Because of the internal design of a wedge gate valve, the seats move
    inward at an amount greater than the wedge shrinkage occurring
    during cooldown. The difference in thermal contraction can bind the
    wedge tight enough so that it cannot be reopened until the system
    temperature is raised enough to reheat the valve.

9)  Solid wedge gate valves in systems where severe temperature changes
    occur are also subject to excessive seat leakage due to changes in
    angular relationship between the wedge and the seat faces due to
    pipe loads exerted on the valve ends.

10) Metal-seated gate valves should not be used for air or gas service
    because they do not have the bubble-tight closure necessary for
    these services.

## Globe Valves

![](media/image4.png){width="1.0402777777777779in"
height="1.6444444444444444in"}Globe valves are also very commonly used
in industrial applications. The globe valve controls flow by lifting or
lowering a circular disc on a seat designed to accept the contour of the
disc. Globe valves are commonly used as throttling valves as well as
stop valves. The throttling capability of the valve is very dependent on
the design of the disc. In most cases, discs furnished are of the
"quick-opening" or "semi-throttle" designs, which do not provide for
very accurate throttling. If additional throttling is required, other
disc forms are available on special order, such as the "linear" and
"equal percentage" designs, which provide much better throttling
characteristics. These characteristics of the valve operation may be
important if the valve is required for throttling service. Globe valves
can be used in gas applications and provide "bubble-tight" closure if
the discs are furnished with resilient inserts. Some examples of typical
globe valves disc designs are shown in the following figure. Note that
the V-Port type Plug Disc is usually intended for fine throttling
applications, and the other discs fall into the quick-opening or
semi-throttle category.

![](media/image5.png){width="4.500694444444444in"
height="1.5833333333333333in"}The globe valve has historically been used
primarily for throttling service. In some cases where system flow can
reverse, the globe valve has been used as a stop valve (where the
pressure is acting on top of the disc and tending to force the valve
closed). Small globe valves 2 inches and smaller may be used as stop
valves because the force under the disc is within the capability of the
stem threads to keep the valve closed. In throttling service (being
partially opened the majority of the time), the valves must be equipped
with deep stuffing boxes, and the disc should be guided along full
travel.

Additionally, globe valves are used for services requiring frequent
operation and positive shutoff.

The maximum differential pressure across the valve should not exceed 20
percent of the upstream line pressure and never exceed 200 psi, unless a
special trim and disc design is provided by the manufacturer.

Small globe valves can be used as piping or equipment high point vent or
low point drain connections as well as root valves for instrument
pressure connections. Globe valves with special trim are used for
blowoff or blowdown system applications.

Globe valves are available in various body configurations. Some
advantages of these different configurations are:

1)  Tee Pattern (standard): When severe throttling is required as in a
    bypass line around a control valve where pressure drop is not a
    concern. This pattern has the lowest Cv.

```{=html}
<!-- -->
```
11) Wye Pattern: When valve is normally wide open and throttling during
    seasonal or startup operations is required. This valve type has very
    little resistance to flow and can be "cracked open" for long periods
    without severe erosion.

12) Angle Pattern: Similar in application to the wye pattern globe with
    a slightly lower Cv. A particularly good selection for systems that
    have periods of pulsating flow because this valve configuration
    adequately handles the "slugging" effect inherent with this type of
    flow.

## Butterfly Valves

![](media/image6.png){width="1.0583333333333333in"
height="1.3534722222222222in"}The butterfly valve (also called a
trunnion valve) is a quarter turn valve that rotates a disc in the flow
stream. These valves were originally intended to be lightweight,
non-leaktight seating dampers. Many varieties of this valve are still
intended for this "non-leaktight sealing" service, however design
improvements in high performance butterfly valves have produced some
which are acceptable for high pressure, high temperature service with
bubble tight closure.

Butterfly valves are generally used as stop valves for throttling
purposes in water systems. In particular large diameter piping systems
of ANSI Classes 150 and 300 with resilient seating materials and much
higher class ratings for metal seating materials are poorly suited for
stop valve service. Smaller butterfly valves are used in piping
arrangements where space limitations dictate their use over
dimensionally long valve types.

In addition to the price advantage in the large sizes, the butterfly
valve also has a definite weight advantage. The following is a typical
weight comparison when using an ANSI Class 150 wafer style butterfly
valve:

Butterfly = 53 lbs.

Ball = 158 lbs.

Gate = 310 lbs.

Butterfly valves fall into the category of "flow sensitive valves"
because the disc movement is unguided and their operability is affected
by incoming turbulence. Close proximity of the butterfly valve to
certain piping components can amplify the normal dynamic reactions. For
example, the velocity profile of the discharge of a pump is not
symmetrical. When installed at the discharge of a centrifugal pump with
a vertical shaft, the result can be fluid dynamic torques that are twice
the magnitude of those found for a valve with straight run of pipe
upstream. The eccentric forces applied to the valve disc produces
excessive vibration and "disc flutter" which eventually results in a
complete breakdown of the valve.

Butterfly valves may be used for throttling service. However, in
throttling applications, the major concern for the valves is cavitation.
The recommended range of flow control is between the 30° and 80° disc
opening, although throttling operations require individual study.
Acceptability of throttling performance may also depend on the location
of the valve in a piping run and whether the valve has a free discharge
or discharges into a closed system.

## Ball Valves

![](media/image7.png){width="2.341666666666667in"
height="1.4833333333333334in"}The ball valve is another quarter turn
valve, and consists of a highly polished spherical ball with an opening
(port) bored through the center. The ball is wedged between two seat
rings, which are typically a relatively soft material (Teflon, Viton,
EPDM, etc). Valve operation involves rotating the ball to either align
the port with the flow stream to open the valve, or aligning the solid
portion with the flow stream thereby closing the valve.

All 2-way ball valves furnished with two seat rings are bi-directional;
flow entry can be from either end without comprising the function of the
valves. However, single seated valves have a "preferred" entry and are
therefore classified as "unidirectional." Another condition that makes a
ball valve unidirectional is when the valves are furnished in the 3-way,
4-way, or 5-way designs where flow must enter a designated port in order
to divert the flow toward the established direction. Because of the
complicated machining process within the ball discs for multiport ball
valves, sharper turns are necessary so resistance to flow is a necessary
result when compared to the traditional 2-way valve.

Ball valves are used as bubble-tight stop valves for relatively clean
fluid systems, such as air, water, and gas. The popularity of this valve
is enhanced by its very small space envelope for a given line size and
its quarter turn operation from the closed to open position.

The multiport ball valve is used frequently for diverting flows to
several directions using a single valve. In addition, the valve
(manually actuated) has a very low center of gravity and is constructed
of a very simplified design. With its few moving, and accessible parts,
this valve design rates very high with respect to maintenance costs. The
temperature limitations for the various seat and seal materials give a
wide range of service temperature conditions that can be accommodated.
Standard ball valves should not be used for any sustained throttling
(over 2 hours at a maximum differential pressure of 50 psi) as severe
erosion of the ball and seat ring may result. However, several
manufacturers have specific ball valve designs that are intended for
throttling service.

The ball valve has a generic design problem that exists when suspended
solid particles in the fluid system (resins, oxide particles, etc.)
settle-out and become trapped in the cavities below the ball and in the
vicinity of the stem or trunnion areas. This occurs typically when flow
has stopped and this "crud" has had time to become encrusted. One
solution to this problem is to position all valves mounted in a
horizontal run of pipe so that the stems or turnings are on the
horizontal. This valve position will promote the "self-scouring " motion
when flow returns.

Multiport ball valves can provide the function of two or more valves
when used in systems where flows are frequently diverted to various
directions. The flow inlet and outlet ports designated by the
manufacturer should not be altered to avoid "by-passing" between ports.

## Plug Valves

![](media/image8.png){width="1.5666666666666667in"
height="1.8166666666666667in"}The plug valve is very similar to the ball
valve except that instead of a ball with a port, a cylindrical plug with
an elliptical or round port is used. Plug valves are used as
bubble-tight, on-off stop valves in a variety of fluid systems,
including air, gas, oil or oil mixtures, and liquid slurries.

Due to the fact that the plug sealing methods do not promote "crud
traps" or internal pockets where deposits could accumulate, plug valves
have functioned successfully with dust, dirt, or other gritty
contaminants suspended in the above systems.

The unique quality of this valve, to be "self cleaning" by automatically
"wiping off" accumulated deposits in the closed position as the plug is
rotated, makes this valve highly recommendable for contaminated systems.

Plug sealing is accomplished using one of two methods: (1) a sealant
forced into machined passages around the valve ports, and (2) a
resilient liner or sleeve into which the machined tapered plug is
forced. The sealant also acts as a lubricant and can typically be used
in systems whose service temperature is as high as 650 F. The resilient
material (usually an elastomer) is limited by the temperature rating of
the sleeve material. In systems such a demineralized water, where
conductivity is monitored and should not be exposed to contaminants, the
lubricated plug valve should not be used.

Throttling service should not be the primary function of a plug valve.
However, if throttling accuracy is not important, non-lubricated plug
valves may be used if the valve is equipped with a device to hold the
plug to a "set" position and prevent "drifting" to the closed position.
Lubricated plug valves should not be used for throttling because the
sealant grooves adjacent to the port opening would be exposed to the
flow stream and a considerable amount of sealant would be "washed away"
by the system fluid velocity. Cylindrical plug valves, particularly
those with round ports, are not produced by many manufacturers so the
justification for selection of this type of valve must be based upon
specific system requirements.

## Check Valves

The check valve operates automatically to pass flow in one direction,
and prevent any reversal of flow. The valves typically give no
indication of setting, or warning of its condition. These valves are
also referred to as non-return valves, and are not usually intended to
provide a tight shutoff function. There are numerous check valves types
and configurations. Some of the more common types include: the swing
check, the lift check, the tilting disc check, the folding disc check,
and the stop check. Different services may require different types of
check valves. It is important to consider the required velocity to fully
open the check valve, closure time on flow reversal, and other operating
characteristics when selecting a check valve. Much of this information
is specific to a particular valve and is available only from the
manufacturer.

### 5.6.1 Swing Check

![](media/image9.png){width="1.6583333333333334in" height="1.475in"}The
swing check valve is widely used because most system flow conditions
(velocity and pressure) are within the acceptable range recommended for
this valve. Body configurations are available in Tee, inclined or Wye,
and wafer styles. The majority of these valves have "swings" or hinges
near the top of the valves or near the access point. Swing check valves
typically (except for wafer types) have top access to the valve
internals for replacement of parts or seat refinishing.

Seat materials vary for swing check valves and are dependent on service
requirements. Seating may be metal-to-metal or metal to resilient
material, and may be either integral or replaceable. Seating angles vary
from 0° to 45° and serve two purposes:

1)  The length of disc travel is reduced with a higher seat angle. Thus,
    the danger of water hammer may also be reduced with a quicker
    closing disc.

```{=html}
<!-- -->
```
84) When swing check valves with a vertical seat (0° angle) are located
    in horizontal runs of piping, slight slopes may cause the valve to
    hang open. A seat angle of 5° to 7° can typically correct for this.

The seating surfaces have a broad contact area due to the problem of
seat alignment. The swing disc is unguided along its full travel and
depends on a hinged action that must maintain relatively loose
tolerances to accomplish, at best, a fair leak tight seating. The
looseness provided at the disc connection to its holder or pivot arm
allows the disc to rotate under turbulent flow. This rotation has
contributed to some cases of discs separating from their holders. The
engineer may need to place special emphasis on the disc connection
details of the holder and method of fastening.

It is important that the service conditions ensure the disc remains in
its full open position to prevent disc flutter that can damage the
valve. Swing check valves have a tendency to "slam" shut on flow
reversal. This shortens the life and leak tightness of the seating
surfaces. Some manufacturers offer options such as an outside lever to
control the travel time of the disc.

### Lift Check

![](media/image10.png){width="1.5583333333333333in"
height="1.3833333333333333in"}

The lift check is another widely used check valve. It is more versatile
than the swing check in that some designs will adapt to pulsating flows
and, in general, can be used in higher velocity systems. The seating
arrangement is similar to that of the globe valve with fully guided disc
travel and point contact seating surface interface, which results in
better leak tightness than the swing check.

Body configurations are similar to those of globe valves with similar
loss characteristics. Lift check discs are available in the form of a
piston (or poppet) and a ball. The ball lift check is typically used for
highly viscous fluids where low velocities do not cause excessive ball
rotation.

### Tilting Disc Check

tilting disc check valve was intended to provide a compromise between
the swing check and the lift check. The main features of this valve are
a reduction in the slamming effect of the disc on flow reversal and a
very short length of travel that results in a quick closing valve.

This type of check valve typically provides access to the internals for
maintenance.

### Folding Disc Check

![](media/image12.png){width="1.8666666666666667in"
height="1.8833333333333333in"}The folding disc check valve (also
referred to as the split disc check) utilizes a disc that folds in the
middle of the flow stream to permit flow. This type of check valve is
used for its space savings features and its quick closing capability.
These valves are available from a relatively limited number of
manufacturers compared to other types of check valves. It can be mounted
in almost any position because it uses a positive force (typically a
spring) to provide the closing force.

These valves have many seating material options both in the resilient
type or metal to metal type, and are manufactured for various services
including air or gas. One good feature of the folding check valve is
that there are no internal fasteners to become loosened and cause a
breakdown in the valve function.

### Stop Check

The stop check valve combines the normal free operating functions of a
check valve, with the additional capability of providing a temporary
stop valve function. To accomplish this they are fitted with a
screw-down stem that is not fastened to the disc, but can hold the disc
in the closed position. These valves are manufactured either as swing
checks or piston lift checks.

These valves must be furnished with a bonnet to contain the stuffing box
necessary to provide a dynamic seal around the stem. This necessitates
additional material considerations for stem, packing, etc.

## Materials

Selection of the proper materials to resist degradation to the desired
service conditions is crucial in the selection of the proper valve. This
can be a very simple decision for services such as low
pressure/temperature air and water, or a very difficult decision for
more severe services such as radioactive wastes and hazardous chemical
solutions. Resistance of various metals, elastomers, and packing
materials to chemical attack can be found in various valve manufacturer
catalogs and material handbooks. Some guidance for selection of valves
for common fluid services is also provided in Appendix B. See Appendix C
for additional discussion on materials selection.

## Procurement Level

A graded approach to valve procurement is the responsibility of the
cognizant engineering organization based upon the service requirements,
level of quality assurance required, and the functional classification
of the service. Where specific materials are not crucial to the service,
and the service is not safety related, lower levels of quality assurance
may be acceptable. Where specific materials are required for the correct
functioning of the system, quality control checks at receipt inspection
should be considered as a minimum. It should also be noted that, for
ASME B31.3 systems, material verification in accordance with ASME B31.3
is required (at the percentages noted in that code), and procurement
requirements or receipt inspection has no relation to this requirement.

## Valve Specifications

The valve style numbering system provided below was developed to provide
the cognizant engineer with a convenient method of identifying the
desired features in valve procurements. The style number system provides
a method of alpha-numeric identification of valves and should be used
for identifying valves on the design drawings and/or Bills of Material.
This system should be used in addition to the unique component numbering
system required by ESM Chapter 1, Section 230, Component Nomenclature.

The following page provides a description of the numbering scheme for
the valve specifications. The following **general notes** are applicable
to all of the valve specifications:

1)  Desired features that are required by the engineering design but not
    identified in the style valve number must be noted in the
    procurement documents and on the applicable design drawings.

```{=html}
<!-- -->
```
13) Not all possible combinations of materials are necessarily
    available. Some combinations may require extensive lead times and
    high cost. The purchaser should take care to specify only what is
    required by design, and should consult available manufacturers to
    decide between acceptable options on the basis of what may be
    readily available.

14) Acceptance of valves that do not specifically conform to all
    requirements of one of the listed standards (Table D-1) is at the
    discretion of the cognizant engineer, and may required additional
    qualification to comply with the applicable piping code (e.g.
    qualification as an unlisted component per ASME B31.3).

15) Valve materials identified are those that are commonly available.
    Other materials may be available, and material availability changes
    over time with the advent of new and better materials. The valve
    style numbering system is controlled by the ESM Mechanical
    Point-of-Contact, and consideration will be given to any additions
    required by specific facilities on a case by case basis.

16) For austenitic stainless steel valves with welded ends (socket weld
    or butt weld), the low carbon alloys are required (e.g. F304L, CF3,
    F316L, or CF3M).

## Replacement of Existing Valves

It is important to remember selection of the proper valve for a
particular service is an engineering decision, and replacement of
existing valves should be with a new valve that has all of the features
required by the design. If the specific features that the cognizant
engineer originally required are not known, replacement should be in
kind unless the valve did not perform satisfactorily.

Replacement of a valve that did not perform acceptably in a given
service is the responsibility of the cognizant engineer. The cause of
the unsuitability of the valve (e.g. material compatibility, functional
problem, etc.) should be determined before a replacement valve is
specified.

# APPENDIX E -- FLANGED CONNECTIONS

## Introduction

The guidance provided by this appendix is based on ASME B16.5 flanges.
The majority of this guidance is representative of "good practices" that
applies to the installation of many types of pipe flanges. Torque values
presented herein are based on ASME B16.5 flanges and should be confirmed
by engineering prior to use with other flanges.

Many factors can affect the ability of a flanged joint to establish an
initial seal and maintain that seal during service for an extended
period of time. One of the most important considerations is proper
flange installation. The following guidance is provided to ensure that
flanges are installed correctly either during initial installation or
during maintenance activities.

ASME B31.3 recognizes a variety of national flange standards as "listed"
components, including the following:

ASME 16.1 "*Cast Iron Pipe Flanges and Flanged Fittings, Class 25, 125,
250 and 800,*"

ASME 16.5 "*Pipe Flanges and Flanged Fittings,*"

ASME B16.36 "*Orifice Flanges*,\"

ASME B16.42 "*Ductile Iron Pipe Flanges and Flanged Fittings, Class 150,
and 300,"*

ASME B16.47 "*Large Diameter Steel Flanges, NPS 26 Through NPS 60,*"

AWWA C207 "*Steel Pipe Flanges,"*

MSS SP-44 "*Steel Pipeline Flanges,*" and

MSS SP-51 "*Class 150LW Corrosion Resistant Cast Flanges and Flanged
Fittings."*

## Pre-Assembly

Prior to assembly ensure that the following actions are completed.

1)  Fastener materials shall be free of nicks, burrs, chips, dirt, and
    damage (inspect threads, shank, and nuts). All damaged fasteners
    must be replaced.

```{=html}
<!-- -->
```
17) Flange faces (both raised and flat) must also be clean and free of
    debris or foreign material. Imperfections such as nicks, dents or
    gouges will affect the gasket's ability to seal. The following table
    may be used to determine the allowable size of imperfections for
    ASME B16.5 flanges. Multiple imperfections must be separated by at
    least four times the permissible radial projection, and no
    protrusions above the serrations are permitted. For smooth flange
    faces, the right hand column values should be used. The
    applicability of this criteria to other types of flanges should be
    evaluated on a case by case basis.

TABLE 1 - Permissible Imperfections

  18" through 24"    0.50"                      0.25"
  ------------------ -------------------------- --------------------------

18) Gaskets used in ASME B16.5 flanges must satisfy the requirements of
    ASME B16.20a for metallic gaskets and ASME B16.21 for non-metallic
    flat gaskets. Gaskets used in ASME B16.1 flanges must comply with
    ASME B16.21. Table 2 provides groups different gasket types to be
    used for the selection of torque values. Refer to Appendix C for
    guidance with materials selection.

+----------------------+----------------------+-----------------------+

Notes: 1. Group I gaskets should only be used with flat face flanges.

19) With flat sheet non-metallic gaskets, thinner gaskets are preferred
    (typically 1/16\").

20) Ensure that gaskets are of the correct material and size. Gaskets
    must be clean and not bent, broken, torn or distorted in any manner.
    The allowable shelf life must be checked.

21) No more than one gasket shall be used between contact faces in
    assembling a flanged joint.

22) Flange surface finish (roughness) should be compatible with the
    gasket material. Soft gaskets such as neoprene should have a rough
    finish (e.g., 250AA) and flat metal gaskets should have a smoother
    finish (e.g., 32AA). The typical finish provided on B16.5 flanges
    (i.e., 125μin to 500μin) is normally acceptable for use with gaskets
    listed in Table 2

23) Use only calibrated torque wrenches and multipliers. Examine the
    torque wrench for proper calibration, damage, and proper range.
    Torque wrenches can be used only within the range specified by the
    wrench manufacturer. Specified working ranges typically vary from
    25% - 75% to 20% - 100% of the full torque wrench range.

24) Appropriate calculations must be made when using multipliers, a
    crows foot, or any other attachment which adds length to the torque
    wrench (cheater bars are not acceptable).

## Assembly

The following instructions provide guidance for proper assemble or
re-assembly of a flanged connection.

1)  Prior to bolting up, flange faces shall be aligned properly.
    Ideally, the flange faces should be parallel to within 1/16 in/ft
    (0.5%) measured across any diameter and the bolt holes shall be
    aligned within 1/8" maximum offset (ref. Figure 1). Table 3 presents
    the required alignment for Class 150, 300, and 600 Flanges. The
    values for Class 600 flanges may be applied to high classes of steel
    flanges as well.

Fiqure 1 - Flange Alignment Requirements per ASME B31.3

25) The proper lubricant shall be used on threads of bolts and nuts. Use
    low or no chloride content lubricants with stainless steel (e.g.,
    Fel-Pro C-100 Antiseize Compound).

26) Use hardened steel washers and/or lubricate smooth face of nut
    (i.e., face under compression load). Raised lettering on the nuts
    must be faced outward.

27) All nuts must be snug tight prior to torquing.

28) Torque values are a function of both the gasket and fastener
    materials as well as the size and class of flange. Application of
    the torque values listed in Table 4 ensure that gaskets receive the
    proper pre-load stress. These torque values are sufficient to seat
    the listed gasket materials. When significant external mechanical or
    thermal loads are imposed on a flanged joint, additional evaluation
    by engineering may be required.

Specific Notes:

> 1\) Left column torque values are based on a gasket hardness of Type A
> Shore durometer \< 50. Right column torque values are based on Type A
> Shore durometer ≥ 50. 2) Not recommended for fluid services that
> exceed 125 psig. 3) Do not use A193 B8 Class 1 or A307 fasteners. 4)
> Do not use A193 B8 Class 1 fasteners. 5) Use only A193 B7 fasteners.

General Notes:

• Table is based on ASME 16.5 flanges with properly sized bolts.

• Torque tolerances:

± 2 ft-lbs if torque value is ≤ 50 ft-lbs

± 4 ft-lbs if torque value is ≤ 100 ft-lbs

± 4% of torque value if \> 100 ft-lbs.

• For sheet gaskets, torque values can be used for 1/32" through 1/8"
thick gaskets.

• Contact engineering for assistance with torque values outside the
scope of this table.

29) Table 5 provides the maximum allowable torque values for common bolt
    materials. These torque values shall not be exceeded. Note that some
    of these bolt materials are not acceptable for the torque values
    listed in Table 4. The torque values listed in Table 5 result in a
    preload stress of 90% of the ASME B31.3 Specified Minimum Yield
    Strength.

31) Other, more accurate, methods of obtaining preload such as bolt
    tensioners or measurement of bolt elongation may be substituted for
    torque wrenches if performed in accordance with an approved
    procedure.

32) Preload of elastomeric gaskets used with other types of flat faced
    flanges (fiberglass, aluminum, etc.) should be based on an
    acceptable leak test. In general 20% - 25% compressive deflection of
    the gasket will place the material in its most favorable sealing
    condition.

33) The pattern in which bolts are tightened is extremely important. If
    performed improperly, tightening can cause the flange to move out of
    parallel. A staggered crisscross-torquing pattern, shown in the
    following sketch, must be used to tighten the bolts. No more than
    one third of the final torque should be achieved during a single
    step.

Figure 2 - Typical Torquing Sequences

34) Following the first torquing pass confirm that the flanges are
    parallel. If flanges are not parallel at this point, make two
    complete passes around the flange at 1/3 of the specified final
    torque to equalize load in the fasteners and examine again for
    parallelism. If the flanges are not parallel and full face contact
    has not been achieved, engineering must evaluate for excessive
    misalignment.

35) The following table is based on ASME/ANSI B16.5 and provides
    fastener information for commonly used flange classes.

Notes: 1. Bolts refer to all types of threaded fasteners used in flange
joint assembly (ref. section 6.0).

36) When sequential torquing is complete, use rotational and reverse
    rotational tightening to check that all nuts are stable. Nuts are
    stable when the torque wrench does not turn before the wrench
    achieves the final bolt torque value.

37) Nuts shall have full thread engagement on the bolts or studs. One to
    two exposed threads is the preferable requirement that defines full
    thread engagement. The minimum acceptable engagement is the outer
    edge of the nut being not less than flush with the end of the bolt
    or stud.

38) After leak test and system startup, thermal expansion, creep
    relaxation and fastener thread embedment can change the fasteners'
    applied load. Therefore, a re-check of each fastener is recommended
    especially for piping systems that have non-metallic gaskets and
    operate at temperature levels above 200°F.

## Disassembly

Prior to disassembly match mark the flange rim (if appropriate) to
ensure that the flanges are reinstalled in their original configuration.
Ensure that the following tasks are performed following disassembly:

1)  Adequate controls are in place to maintain cleanliness.

```{=html}
<!-- -->
```
39) Proper cleaning materials are used to clean the flange face and
    bolting materials.

40) Ensure that precautions are taken to prevent sealing surfaces from
    being damaged.

## Trouble Shooting

If a gasket assembly leaks, certain attributes can be inspected in the
removed gasket that may help identify the cause of failure. The
following examinations should be performed.

1)  Examine the gasket to determine if it was damaged during
    installation (e.g., a roll over at the edge of the seating surface).

```{=html}
<!-- -->
```
41) Check for chemical attack and over/under compression.

42) Check for application of an anti-stick or anti-seize compound. These
    materials can lower the performance of the gasket.

43) Examine the gasket seating surfaces for indications of proper
    compression and flange face finish.

44) Measure the thickness of the gasket material around the
    circumference of the seating surface. Compression of the gasket more
    towards the OD of the seating area than the ID is an indication that
    flange rotation has occurred due to over torquing or excessive
    mechanical loads.

45) Leaking flanges may be tightened an additional 10% above the
    recommended values in Table 4 provided that the torque does not
    exceed the maximum allowable value listed in Table 5.

## Threaded Fasteners

Threaded fasteners used in flange joints are typically of three
different structural shapes; double ended studs, heavy hex bolts, and
heavy hex screws.

Studs used in flanges are made from rod and typically are threaded on
both ends. The shape of the most common type used in flanges, the
double-ended stud, is shown in the following sketch. This type of stud
has an unthreaded portion in the middle with ends that are either
rounded or flat and chamfered.

![](media/image15.png){width="2.526388888888889in"
height="0.7493055555555556in"}

Heavy hex bolts are externally threaded fasteners designed for insertion
through holes in assembled parts, and are normally tightened or released
by torquing a nut.

![](media/image16.wmf){width="1.9694444444444446in"
height="0.7979166666666667in"}

Heavy hex screws are externally threaded fasteners designed for
insertion into holes in assembled parts or mating with preformed
internal threads and are normally tightened by torquing the head. The
primary difference between a hex bolt and a hex screw is the washer face
shown in the following sketch.

![](media/image17.wmf)

Heavy hex screws and heavy hex bolts that comply with ASME B18.2.1 are
interchangeable regardless of the material specification (e.g., ASTM
A307). In some sizes, fastener manufacturers opt to produce only heavy
hex screws in lieu of heavy hex bolts due to the interchangeability and
greater range of application.

When zinc coating is required, all components of mating fasteners (e.g.,
bolts, nuts, and washers) shall be coated by the same zinc-coating
process.

# APPENDIX F -- ALIGNMENT FIT-UP TOLERANCES

This Appendix provides guidance on ASME B31.3 Code paragraph 335.1.1
"Alignment." Specifically two sections of the Code are addressed
335.1.1(a) Piping Distortions and 335.1.1(c) Flanged Joints. The data in
this Appendix is applicable to either initial installation of the piping
system or when performing routine maintenance activities.

## PIPING DISTORTIONS

The Code defines piping distortions as any distortion of piping to bring
it into alignment for joint assembly that introduces a detrimental
strain in equipment or piping components. The Code does not provide
criteria on how to evaluate detrimental strain. A limited degree of
strain is acceptable for overcoming misalignment at the final closure
points in the erection of piping. The amount of misalignment a pipe
joint can tolerate is based upon the degree of inherent flexibility
available in that system. The degree of acceptable misalignment may be
considered as an alignment tolerance.

The methodology applied in Tables 1 and 2 is limited to, three
directions of misalignment or displacement misfit at a closure point.
The three directions of misalignments are the two axial or lateral
directions and face-to-face misalignment. Axial or lateral misalignment
is the degree of centerline offset between adjoining sections.
Face-to-face misalignment is the amount of separation between adjoining
sections that are parallel. In all cases, the two weld-ends at the
closure must be parallel within weld fit-up tolerance after
cold-pulling. Where this does not occur, one or both weld-ends must be
re-beveled for an acceptable fit-up.

The data provided in Table 1 and 2 below should be used as acceptable
tolerances on closure fit-up in Code piping systems. Pipe closures made
by butt welds, socket welds, and flanged are acceptable when applying
the data in Tables 1 and 2.

Table 1 applies only to "strain sensitive" piping systems; those piping
systems connected to rotating machinery such as pumps, small turbines,
compressors, and unanalyzed vessel and tank nozzles.

Table 2 applies to the non-strain sensitive closures in piping systems.

The lengths of piping tabulated are the minimum total lengths of pipe
required which must lie in a direction perpendicular to the direction of
a single degree of misalignment to safely permit cold pulling the pipe
to close. The example below demonstrates the use of the tables.

Where more than one final closure point occurs in the same system (e.g.
between equipment nozzles or full anchor or any combination of these)
the misfits at a single point cannot be evaluated independently. No
attempt should be made to evaluate and close such a misfit until fit-up
conditions are determined in the balance of the system.

When the field misalignments exceed of the values provided in Tables 1
and 2, the piping shall be reworked or evaluated by engineering.

Notes For Tables 1 and 2:

1)  The length of piping available for the evaluation of a misfit
    variation in a particular direction is the sum of the piping leg
    lengths perpendicular to the direction of the misfit variation,
    only.

2)  Values of the variations and the required pipe lengths for the
    variations may be interpolated in the table.

3)  The tables provide the minimum piping length in units of feet
    required to accommodate a misfit error in any direction.

**EXAMPLE:**

Figure 1 illustrates a simple two-ended piping system with three
directions of misfit at the final closure point. Each direction of
misfit must be evaluated separately as follows.

**[For the ∆X misfit of 0.50"]{.underline}**

The total length of piping perpendicular to ∆X (six legs) equals 74
feet; the minimum length required for a 0.50" misfit in 10" piping in
Table 1 is 44.0 feet. Since the available piping exceeds this, the
misfit is acceptable.

**[For the ∆Y misfit of 0.75"]{.underline}**

The total length of piping perpendicular to ∆Y (six legs) equals 119
feet; the minimum length required for a 0.75" misfit in 10" piping in
Table 1 is 53.8 feet. Since the available piping exceeds this, this
misfit is also acceptable.

**[For the ∆Z misfit of 0.40"]{.underline}**

The total length of piping perpendicular to ∆Z (four legs) equals 77
feet; the minimum length required for 0.40" misfit in Table 1 is 39.3
feet. Since the available piping exceeds this, the ∆Z misfit is
acceptable, as well.

In this example, since all directions of misfit are within the allowance
limitations, the piping may be cold-pulled to fit-up alignment.

## FLANGED JOINTS

The ASME B31.3 Code provides a rotational misalignment criterion for
flanged Joints. Rotational misalignment is the amount the flanges are
out-of-parallel. The Code criterion requires that prior to bolting,
flange faces shall be aligned to the design plane within 1/16 in./ft
measured across any diameter. During field assembly these tolerances may
be difficult to achieve, especially for small flanges. Allowable flange
rotational misalignments above those in the Code are provided in Table 3
for flange assemble with the limitations provided below. Table 3
provides an allowable gap based on the distance between two closest
supports as shown in Figure 2.

The gap values provided in Table 3 apply to flanges fabricated to the
following listed standards: ASME B16.5, AWWA C207, and MSS SP-44.

The flanges shall be assembled using the flange assembly procedure in
Appendix E of this procedure.

The allowable gap values provided are to be compared to measurements
taken prior to applying any preload (torque) to the flange bolts.

When these allowable gap values are applied, the required bolt torque to
assemble the flange should be those provided in Appendix E with a 20%
increase.

When these allowable gap values are applied during assembly, it is
required to recheck the gap between the flange faces after 1/3 of the
total required torque is applied to the bolts. After 1/3 of the torque
is applied to the bolts, the maximum difference in gap must be within
the ASME B31.3 requirements (flange faces must be parallel to within
1/16 in/ft measured across any diameter). If the gap is not within the
B31.3 requirement after 1/3 of the total torque is applied rework or an
engineering evaluation is required.

# APPENDIX G -- COMPONENT IDENTIFICATION

The ASME B31.3 Code requires random examination of materials and
components to ensure conformance to listed specifications and standards.
B31.3 also requires these materials to be free from defects. Component
standards and specifications have various marking requirements. The
intent of this appendix is to provide a convenient easy-to-use summary
of the marking requirements for several commonly used piping components.

# APPENDIX H -- LEAK/PRESSURE TESTING

## PURPOSE

This Appendix provides guidance for hydrostatic and pneumatic tests. The
specific code requirements are contained in paragraph 345 of ASME B31.3.

## SCOPE

The information in this Appendix applies to the testing of metallic
Category D and Normal fluid service process piping systems constructed
to ASME B31.3 "Process Piping". Nonmetallic piping and other fluid
service categories have additional requirements.

## GENERAL

### Test Preparation

1)  All Code and design required examinations shall be complete prior to
    testing

```{=html}
<!-- -->
```
85) A preliminary walk-down of the piping to be tested shall be made.
    Test personnel shall correct and/or identify test boundaries, any
    problems, incomplete items, joint access, fill points, vent points
    and any scaffolding required.

86) All joints, including welds and mechanical joints are to be left
    un-insulated and exposed for examination during the test, except
    that joints previously tested may be insulated or covered.

87) Hangers and supports shall be placed in the proper position prior to
    the filling of the system to be tested.

88) Piping designed for vapor or gas shall be provided with additional
    temporary supports, if necessary to support the weight of the test
    liquid, as designated by the designer. Spring hangers should be
    placed in the locked position.

89) Expansion joints shall be provided with temporary restraint if
    required for additional pressure load under test, or shall be
    isolated from the test.

90) The test personnel shall assure that the components (e.g.
    instruments, valves, etc.) that are not to be subjected to the
    pressure test, are either disconnected from the piping or isolated
    by blind flanges or other means during the tests. Valves may be used
    for isolation, provided the valve (including the closure mechanism)
    is suitable for the proposed test pressure.

91) A flanged joint at which a blank is inserted to isolate other
    equipment during the test need not be examined for leaks. These
    joints should be leak tested during initial service.

92) If a pressure test is to be maintained for a period of time and the
    test liquid in the system is subject to changes in temperature,
    precautions shall be taken to avoid excessive pressure due to
    thermal expansion or freezing.

93) A preliminary air test at not more than 25 psi gage pressure may be
    made prior to hydrostatic test in order to locate major leaks.

94) A test record shall be made for each leak test. The record shall
    include the following:

95) Date of test

96) Identification of piping to be tested (test boundaries)

97) Test fluid

98) Test pressure

99) Certification of the examiner

100) An example Pressure Test Record is provided at the end of this
     appendix.

101) Following hydrostatic or pneumatic leak testing, the piping system
     should be cleaned, and dried if necessary. Refer to Appendix K for
     cleaning techniques.

102) Prior to in-service leak test, the piping system should be cleaned,
     and dried if necessary. Refer to Appendix K for cleaning
     techniques.

103) During Hydrostatic testing or in-service leak testing, strainers
     should be used to protect equipment against the introduction of
     construction debris or dirt.

## HYDROSTATIC LEAK TEST

### Test Fluid

1)  The test fluid shall be water unless there is a possibility of
    damage due to freezing, or if the process or piping material would
    be adversely affected by water. In that case other suitable test
    fluids may be used. Special precautions are required if the test
    fluid is toxic or flammable.

```{=html}
<!-- -->
```
104) The temperature of the test fluid should be no less than 40^°^F in
     piping systems subject to brittle fracture (i.e. carbon steel).

105) If the test fluid temperature produces condensation on the piping
     exterior surface, the water shall be heated to a temperature above
     the dew point or the test shall be postponed to a time when the dew
     point temperature has changed sufficiently such that condensation
     will not occur on the piping exterior surface.

106) Material and test water temperature shall be approximately equal
     prior to pressurizing the system.

107) High points in the system shall be vented so that air will be
     displaced while the system is being filled with the test fluid.

108) The operator shall take adequate measures to ensure that the piping
     system is not over-pressurized during hydrostatic testing. Adequate
     measures include a relief valve, or a dedicated operator to monitor
     pressure, or dual pressure regulators, etc.

### Test Pressure

1)  The minimum hydrostatic test pressure for metallic piping shall be
    per the following equation.

    P~T~ = 1.5 x P~D~ x S~T~/S~D~

    where: P~T~ = minimum test gage pressure

    P~D~ = internal design gage pressure

    S~T~ = allowable stress value at test temperature

    S~D~ = allowable stress value at design temperature

    Note: The maximum allowable value of S~T~/S~D~ is 6.5

```{=html}
<!-- -->
```
109) When a maximum test pressure is specified, the test pressure shall
     not exceed this amount.

110) When no maximum test pressure is specified, the test shall not be
     greater than 110% of the minimum.

111) When using water, static head due to differences in the elevation
     of the top of the piping system and the elevation of the test gage
     shall be accounted for in pressuring the piping system to be tested
     by the following equations:

     SH (psi) = (HE - GE) x 0.433

     P~ST~ = P~T~ + SH

     where: HE = high point elevation (ft)

     GE = gage point elevation (ft)

     SH = static head (psi)

     P~ST~ = minimum test gage pressure corrected for static head

     0.433 = conversion factor (ft of waster to psi)

112) Pressure gages should be connected directly to the piping.
     Calibrated pressure gages shall be used in all Code testing.
     Pressure gage range should exceed the intended test pressure by
     approximately double but in no case should the range be less than
     one and one-half (1 ½) times the test pressure.

### Hydrostatic Testing of Piping with Vessels as a System

1)  Where the test pressure of piping attached to a vessel is the same
    as or less than the test pressure for the vessel, the piping may be
    tested with the vessel at the test pressure of the piping.

```{=html}
<!-- -->
```
113) Where the test pressure of the piping exceeds the vessel test
     pressure and isolation is not considered practicable, the piping
     and the vessel may be tested together at the test pressure of the
     vessel, if approved by the design authority. The vessel test
     pressure must not be less then 77% of the piping test pressure.

### Examination For Leaks

1)  Test personnel shall ensure the hydrostatic pressure is maintained
    for sufficient time to determine if there are any leaks. A minimum
    time of 10 minutes is required by Code. After the hydrostatic
    pressure time has been satisfied, all joints shall examined visually
    for leaks.

```{=html}
<!-- -->
```
114) Examination shall be made of all welds and mechanical joints. There
     shall be no visible evidence of leakage. Welds and joints
     previously tested need not be examined for leaks.

115) Leakage detected in welded joints shall be repaired by draining,
     repair welding, non-destructively examining in accordance with
     original requirements, and re-tested to the original test pressure.

116) Mechanical joint leakage at permanent joints shall be repaired,
     examined in accordance with original requirements, and re-tested to
     the original test pressure.

## PNEUMATIC TESTING

### Precautions

Pneumatic testing involves a hazard due to possible release of energy
stored in compressed gas. Care must be taken to minimize the chance of
brittle failure during testing by initially assuring the system is
suitable for pneumatic testing. Pneumatic testing may be used in lieu of
hydrostatic testing, recognizing the hazard of energy stored in
compressed gas, when a hydrostatic test is considered impracticable.
Guidance for when to use a pneumatic test is provided below.

1)  When components, appurtenances, or systems are so designed or
    supported that they cannot be safely filled with water.

```{=html}
<!-- -->
```
117) When components, appurtenances, or systems, that are not readily
     dried, are to be used in services where traces of the testing
     medium cannot be tolerated.

### Test Fluid

Air or Nitrogen shall be used as a test medium unless otherwise
specified by engineering. Special precautions are required if the test
fluid is toxic or flammable.

### Test Pressure

1)  The pneumatic test pressure shall be per the following equation.

    P~T~ = 1.1 X P~D~

    where:

    P~T~ = test gage pressure

    P~D~ = internal design gage pressure

```{=html}
<!-- -->
```
118) Temporary test pressure relief device shall be provided during
     pneumatic testing. The set pressure shall not be higher than the
     test pressure plus the lesser of 50 psi or 10% of the test
     pressure.

### Examination For Leaks

1)  The pressure in the piping system shall be increased gradually in
    steps providing sufficient time to allow the piping to equalize
    strains during the test. When the system pressure reaches the lesser
    of ½ the test pressure or 25 psi a preliminary leak check of the
    system shall be made. Following the preliminary leak check the
    pressure shall be increased gradually until the test pressure is
    reached. The pressure shall then be reduced to the design pressure
    before examining for leaks.

```{=html}
<!-- -->
```
119) Examination shall be made of all welds and mechanical joints. There
     shall be no visible evidence of leakage. Welds and joints
     previously tested need not be examined for leaks.

120) During pneumatic tests, all joints shall be examined with a
     bubble-producing solution specifically compounded for leak
     detection.

121) Leakage detected in welded joints shall be repaired by
     de-pressurizing, repair welding, non-destructively examined as the
     original, and re-tested to the original test pressure.

122) Mechanical joint leakage at permanent joints shall be repaired,
     examined as original, and re-tested to the original test pressure.

## PIPING SUBJECT TO EXTERNAL PRESSURE

### Test Method

Either the hydrostatic or pneumatic test method described above may be
used to test externally pressured piping. The piping shall be tested at
an internal gage pressure 1.5 times the external pressure, but not less
then 15 psi.

# APPENDIX I -- STRESS ANALYSIS

This appendix provides a guide for Stress Analysis and Qualification for
Compliance with ASME B31.3, paragraphs 302.3.5 Limits of Calculated
Stresses Due to Sustained Loads and Displacement Strains, and 302.3.6
Limits of Calculated Stresses due to Occasional Loads of above ground
piping.

## Scope and Boundaries of Piping Systems

The qualification documentation for piping systems analyzed to the
requirements of this procedure should include a system diagram (P&ID
sketch) and a stress isometric indicating the scope and boundaries (end
points) of the analysis. The isometric should include support location,
type and direction, location of components and the coordinate system
(For the purpose of uniformity, coordinates North = + X, Up = + Y and
East = + Z are recommended).

The piping system analytical model should extend to in‑line structural
anchors (six‑way restraints) or nozzles of anchored equipment.
Otherwise, the analytical model should overlap into adjacent piping,
beyond the scope of the system to be qualified. The extent of overlap
should be sufficient to reflect the loading transmitted from the overlap
onto the in‑scope piping system.

For the purpose of analysis, branch lines can be decoupled from the
header piping provided all of the following conditions are met:

• The ratio of branch to header pipe moment of inertia is such that
I~branch~ \< I~header~ / 2S

• The header pipe movements are properly considered in the analysis of
the branch pipe

• When seismic qualification is required, the applied spectra should
envelope the header pipe support attachment points

Applied boundary conditions include differential thermal expansion and
dynamic anchor movements or gaps at building and equipment attachment
points. Differential movements of less than ¼ \" may be neglected,
except at equipment nozzles.

## Pipe Supports and Equipment Analytical Models

The stiffness of pipe supports and equipment should be considered in
dynamic analysis. Supports and equipment may be considered to be rigid
provided either one of the following conditions are met:

• The support or equipment fundamental frequency is greater than the
frequency corresponding to the zero period acceleration

• The support or equipment stiffness exceeds the minimum rigid values of
Table I‑1

Table I‑1

Minimum Rigid Support and Equipment Stiffness

  ----------------------- ----------------------- ------------------------
  Pipe Size               Translational Stiffness Rotational Stiffness
                          (lb/in)                 (in‑lb/rad)

  ≤ ¾ \"                  1E4                     1E6

  1\" to 2\"              1E5                     1E7

  3\" to 4\"              5E5                     5E7

  ≥ 6\"                   1E6                     1E8
  ----------------------- ----------------------- ------------------------

A rigid support or equipment may be assigned the stiffness values of
Table I‑1 or a larger stiffness. Otherwise, the actual support stiffness
should be accounted for.

To reduce unnecessary iterations, it is important that stiffness values
be rounded.

One‑way vertical downward supports may be modeled as two‑way restraints
in dynamic analysis, provided the following four conditions are met:

• The pipe, should it uplift (thermal + seismic up \> deadweight down),
will not fall off the support.

• The support can withstand a total applied downward load equal to twice
the resultant vertical static load plus the calculated vertical dynamic
load.

• The pipe span adjacent to the one‑way support, on either side, does
not contain impact sensitive equipment or components.

• The pipe span adjacent to the one‑way support is not attached to an
equipment nozzle.

The lateral restoring force of rod hangers may be included in the piping
system model, as an equivalent linear lateral stiffness, (k = tributary
weight of pipe span/rod length) from pin centerline to pipe center line
provided the swing angle can be accommodated by the rod and anchor
design.

## Modeling Tolerances

Guidance on tolerances is provided in ASME B&PV Section III Appendix T
-- Recommended Tolerances for Reconciliation of Piping Systems. Layer
tolerances may be applied where the applied stress is a small fraction
of the allowable stress. Tolerance on segment lengths and fitting
locations may be the larger of ±1 foot or ± D/2. Deviations between the
analytical model and the as‑built condition beyond the above tolerances
must be reconciled.

## Loading Conditions

The design documents shall specify the applicable loading, based on the
applicable standard (such as IBC) or typical requirements. The following
load combinations are provided for guidance.

### Load Combinations for the Qualification of Piping Systems

Normal (sustained) P~o~ + DW

Normal (occasional) P~o~ + DW + FT~N~ *or* P~o~ + DW + W~L~

Thermal Th~N~

Faulted P~o~ + DW+(FT~FD~^2^+DBE^2^) ^½^

P~o~ + DW + FT~F~

P~o~ + DW + W~L~

Notes:

P~o~ = Normal system operation pressure

DW = Deadweight

FT~i~ = Fluid transient loads, under plant condition i (normal
sustained, normal

occasional or faulted)

Th~i~ = Thermal expansion or discontinuity stress, under plant condition
i

(normal sustained, normal occasional or faulted). Faulted thermal loads,
Th~F~, need not be considered in piping qualification, but should be
considered in support qualification. Piping Thermal stresses are
qualified separately from other applied loads, as defined in ASME III or
B31.1

W~L~ = Wind loads

FT~FD~ = Faulted fluid transients which result from a DBE

DBE = Design basis earthquake loads equal to the SRSS of inertia and
anchor

motion loads.

## Stress Analysis

### Deadweight Analysis

The deadweight analysis should consider the piping and component weight,
the insulation weight and the weight of fluids contained in the system.

### Thermal Expansion Analysis

A thermal expansion analysis is recommended if one of the following
conditions applies:

• The operating or maximum fluid temperature exceeds 150°F

• The piping is attached to equipment which has nozzle load criteria

• The piping flexibility is judged insufficient to accommodate thermal
expansion.

Thermal expansion analysis should include header and equipment resultant
thermal movements at the terminal and nozzle attachment points.

Thermal analysis shall consider the potential for flow stratification in
horizontal lines subjected to low flow velocities and large temperature
gradients from top to bottom of pipe, with a Richardson number R~i~ \>
1, where:

$R_{i}\text{ = }(\frac{d\rho}{\rho})(\frac{\text{gD}_{i}}{v^{2}})$I

where:

ρ = density of fluid (a function of temperature)

dρ = change in fluid density between max and min. temperature (top to
bottom of pipe)

g = gravitational constant

D~i~ = pipe inside diameter

v = flow velocity

### Pressure Analysis

This Appendix does not address the requirement for system sizing and
process design such as pipe size (and minimum wall thickness), component
ratings, reinforcement of openings, layout arrangements (including
pressure relief) and testing (such as hydrostatic pressure testing).
These requirements should be specified in the project or design
documents, or referred to the applicable Code. Refer to Appendix A.

### Seismic Analysis

When seismic analysis is required, this analysis may be accomplished
using static or dynamic methods, as permitted in the project
specification.

The static seismic analysis is applied to a system or subsystem.

A static load should be calculated in accordance with the applicable
standard (such as IBC or UBC) and is applied to the piping system, in
each of three directions.

If the piping system is rigid, the static load may be equal to the
envelope of the floor response spectra zero period accelerations.

The system response to each of the three one‑directional static loadings
shall be combined by SRSS to obtain the resultant system response,
unless permitted otherwise by the applicable standard (for example,
IBC-2000 permits a two-dimensional load combination, where the resultant
seismic load is the largest of the east-west + vertical and
north-south + vertical).

#### Response Spectra Modal Analysis

The applicable response spectra should envelope the spectra at all
attachment points along the piping system, including the supports from
decoupled headers, in the vicinity of the decoupled branch point.

The three directional response should be calculated by SRSS of the three
unidirectional responses.

Modal combination should be by SRSS of modes, unless specified otherwise
in the project requirements.

High frequency modes (beyond the zero period acceleration or 33 hertz)
should be accounted for as described in USNRC Standard Review Plan
NUREG-0800, Section 3.7.2.

Seismic anchor motions larger than ¼ inch should be evaluated.

The following considerations apply for the dynamic model of the piping
system:

1)  The number of dynamic degrees of freedom, and hence the number of
    lumped masses, should be selected so that all significant modes of
    vibration of the structure below 33 Hz are accurately represented.
    The location of masses will be dependent upon the piping support
    configuration. In addition, mass points should be established at
    concentrated weight locations (e.g., valves, flanges, large
    fittings) and at the centerline of eccentric masses (such as valve
    operators).

```
123) If a support mass is larger than 20% of an adjacent pipe lumped
     mass, the support mass should be considered in the model.

124) Valves with natural frequencies below the zero period acceleration
     shall be modeled to appropriately reflect their actual mass and
     frequency.

Damping of piping system for seismic Design Basis Earthquake response
spectra modal analysis shall be 5% unless specified otherwise in project
requirements.

#### Number range level4Time History Analysis

Seismic time history analysis of a piping system should only be used as
a last resort, where some of the conservatism inherent to the static or
response spectra methods must be eliminated.

The analysis may be performed using either the direct integration
procedure or the modal superposition procedure. In both approaches,
careful consideration should be given to the numerical integration
method being used and the time step of integration. The time step (dt)
chosen should be sufficiently small to capture the significant portion
of response and to ensure that excessive numerical damping is not being
introduced into the response calculations

For modal time‑history superposition, care should be taken to ensure
that all the significant modes of vibration are included in the
analysis.

Responses from the individual modes of vibration included in the
analysis may be combined by algebraic summation of the modal time
histories of response at each time step to determine the individual
component response time history.

The damping and energy dissipation shall be simulated using applicable
procedures of Appendix N of ASME B&PV Code Section III.

When the three components of earthquake motion are statistically
independent, time‑history responses may be obtained individually for
each of the three independent components and combined algebraically at
each time step to obtain the combined response time history.

### Fluid Transient Analysis

Loads resulting from fluid transients (such as opening and closing of
valves, startup and coast down of pumps) should be considered if they
are anticipated occurrences from normal operation of the system.

Fluid transients resulting from Design Basis Accidents should be
identified in the project design documents, and analyzed accordingly.

Unanticipated transients (transients which do not result from normal
operation of the system) need not be analyzed, and should be precluded
by proper operating, maintenance and testing procedures.

### Wind Design

Wind design shall be considered for outdoor piping. Wind loads should be
applied as a uniformly distributed load of magnitude and direction
defined in the project Functional Design Criteria or Design Documents.
Refer to ASCE 7-95 for reference methods.

### Number range level3Piping System Qualification

The requirements of the applicable code shall apply, for the load
combinations defined with the following additions and clarifications:

For B31.1 piping, and B31.3 piping analyzed to B31.1 rules, the
allowable stress for faulted loading should be the minimum of 3S~h~ or
2S~y~.

Higher allowables may be considered based on detailed analysis per ASME
III NB-3200.

Where stress indices and stress intensification factors are not defined
in the Code, they must be justified on a case basis.

Faulted seismic anchor motion amplitudes should be included in the
qualification of piping faulted primary stress. Alternatively, half the
faulted seismic anchor motion amplitude may be added to the thermal
stress range.

The compliance of piping stress to code allowables insures that the
piping cross section and pressure boundary remain intact. In addition,
requirements for equipment and component operability or integrity need
to apply.

Higher allowables or alternate evaluation methods may be used for piping
systems that only need to retain structural integrity (not fall).

### Number range level3Number range level4Qualification of in‑line Equipment and Components

#### Qualification of Active Valves and In‑line Components

The acceleration of active valves (i.e., valves which are required to
change state during or after the DBE, excluding check valves) and
in‑line components should be limited to values provided by the vendor.
When allowable valve and component accelerations are not provided, a
limit of 3g resultant horizontal and 3g (including 1g from deadweight)
vertical should apply at the center of gravity of the actuator.

The nozzle loads on active valves and in‑line components should be
limited to values specified by the vendor. Where allowable nozzle loads
are not specified, the pipe stress at the valve and component nozzle
considering pipe cross-section properties should meet the pipe stress
allowables.

The rules of the DOE-EH-0545 may be used for verification of seismic
adequacy of existing (installed) piping mounted components for existing
systems.

#### Number range level4Flange Qualification

Flanges should be qualified using the methods specified in B31.1 or
B31.3.

### Number range level4Equipment Nozzle Loads

The nozzle loads on equipment should be limited to values specified by
the vendor or derived by analysis. Where allowable nozzle loads are not
specified, the pipe stress at the equipment nozzle shall meet the pipe
stress allowables. Where no vendor limits are specified, the total
stress (primary plus secondary) shall not exceed 0.3S~h~ at the nozzle
of rotating equipment unless justified on a case basis.

### Number range level3Protection Against Seismic Interactions

The seismic qualification of a piping system requires its protection
from credible and significant interactions, and spatial interactions
(falling objects or impact interference with adjacent structures).

### Expansion Joints

Expansion joints should be qualified by comparison of calculated
displacements to vendor allowables or by analysis to the rules of the
Expansion Joint Manufacturers Association as specified in the applicable
ASME B31.1 or B31.3.

# APPENDIX K -- CLEANING CARBON AND STAINLESS STEEL PIPE

### General

The various types of contamination and the methods suitable for their
removal are listed in Table 1. Reference ASTM A380 for more information
on cleaning and descaling stainless steels.

Information on the types of contamination that must be removed shall be
obtained from project specifications or consultation with the
appropriate design authority.

The amount of free iron contamination that can be tolerated and the
extent of the surface area to be tested shall be specified by the
appropriate Design Authority.

### Inspection

All pipe cleaned in accordance with this Appendix should be inspected to
determine the effectiveness of the cleaning method used.

Cleaning methods that are employed solely for the removal of dirt,
paint, metal chips, filings, flux, slag, weld spatter, scale, rust, or
other types of contamination that are easily seen should be visually
inspected with the unaided eye to ensure that the contaminants have been
removed. This inspection should include interior surfaces.

When cleaning methods are used for the purpose of removing grease, oil,
waxes, or other contaminants that may exist as a thin film, items should
be wiped with a clean, white, solvent dampened cloth to ensure that the
contamination has been removed.

Removal of free iron contamination should be confirmed through the use
of a ferroxyl test. The ferroxyl test is highly sensitive and is
required only when traces of free iron or iron oxide would be
unacceptable. 400 Series stainless steels may contain a gray smut after
acid treatments. This smut must be removed by a thorough washing using
water, detergent, and scrub brushes before ferroxyl testing, or the test
will be positive.

### Safety

Use of compressed air creates a hazard from flying particles. Use proper
eye protection.

Mechanical cleaning with power tools using wire brushes, grinding
wheels, and sanding attachments presents hazards from flying particles
and rotating shafts. Use protective clothing and eye protection, and
ensure that clothing will not become entangled in the equipment.

Abrasive blast cleaning presents hazards to personnel. Protective
clothing, eye protection, and in some cases respiratory protection are
required for safe operation.

Use of acids and cleaning agents presents hazards to the environment and
personnel. Environmental restrictions on the use and disposal of
cleaning solutions must be adhered to. Face shields, rubber gloves,
protective clothing, and respiratory protection may be required when
using corrosive chemicals and proprietary cleaners. Consideration should
be given to the proximity of safety showers and eyewash stations.

### Cleaning Methods

**Method A-1, Water Flush.**

Flush pipe with clean water, on stainless steel use only water having a
chloride content less than 50 ppm for the final flush. (Note: domestic
water generally contains less than 2 ppm chlorides).

Dry to conform to system requirements.

**Method A-2, Steam or Air Blow**

Blow pipe with clean, dry, compressed air or steam. Use sufficient
volume of air to create a high velocity stream in the pipe. If air is
supplied form compressors, they shall be equipped with moisture
separators, oil separators, traps, and/or filters, as required to ensure
that the air is clean and dry.

**Method B, Steam Cleaning.**

Use steam at pressures from 50 to 75 psi in conjunction with cleaning
agents such as emulsions, detergents, solvents, and alkalis. Proprietary
cleaners may contain harmful ingredients such as chlorides or sulfur,
which may adversely affect the material to be cleaned, especially in the
case of stainless steel. The manufacturer of the cleaning agent should
be contacted prior to its use when any doubt exists.

Drain pipe and flush with clean water, use chloride free water on
stainless steel. (See method A-1)

Blow dry with clean, dry, compressed air. (See method A-2)

**Method C-1, Blast Cleaning**

Clean, previously unused glass beads, iron free silica, walnut shells,
or alumina sand are required for abrasive blasting of stainless steel
pipe. For carbon steel pipe use sand, steel shot, or steel grit. Blast
clean inside and outside surfaces as required.

Use clean, dry, compressed air. (See method A-2)

Follow with procedure A-1 or A-2.

**Method C-2, Mechanical Cleaning**

Wire brushing, sanding, and grinding are suitable methods for localized
removal of scale and spatter left by welding. Stainless steel wire
brushes are required for use on stainless steel pipe. Grinding wheels,
wire brushes, and sanding materials containing iron, iron oxide, or
zinc, or those previously used on other metals, shall not be used to
clean stainless steel pipe.

**Method D-1, Dehydration of Carbon Steel Pipe for Low Temperature
Service Using Nitrogen**

This procedure is recommended for removal of small amounts of moisture
that may exist in a nominally dry system.

Evacuate system to an absolute pressure of 5 mm of mercury or less. If
it is necessary to dehydrate an outdoor system when the temperature is
less than 36^0^ F, special precautions must be taken to ensure proper
dehydration. These may include sweeping with dry gas, circulating warm
water or brine, blanketing of equipment, or using electric resistance
heaters.

Difficulty in achieving the required vacuum may be due to presence of
excess moisture in the system, leakage of air into the system, a faulty
or inadequate vacuum pump, or the presence of absorbed refrigerant or
moisture in the vacuum pump oil.

If a leak is the suspected cause of insufficient vacuum, perform a leak
test of the required sensitivity to locate the leak(s) and repair.

When the required vacuum is reached, isolate the vacuum pump and let the
system stand for a minimum of 4 hours. A pressure rise of not more than
.4mm of mercury during this period will indicate sufficient dehydration.
After the system is completely dehydrated, charge it with an inert dry
gas suitable to the use of the line. Build up pressure to 50% of design
pressure, tag and seal the system until start-up.

**Method D-2, Dehydration of Carbon Steel Pipe for Low Temperature
Service by the Alcohol Method**

This procedure is recommended where small amounts of water are suspected
in the system, such as in pockets, fittings, and valves.

Drain and dry the system with clean, dry, compressed air. Use resistance
testing to ensure that the system is completely statically grounded.

Fill the system with alcohol (methanol preferred). Make sure all high
spots are vented, and the system is completely wetted with alcohol, then
completely drain the alcohol from the system.

Pull a vacuum on the system, test and fill with inert gas per procedure
D-1 above.

**Method E-1, Sulfuric Acid Cleaning of Carbon Steel Pipe**

Acid cleaning is not effective for removal of greases, oils, and waxes.
Surfaces should be pre-cleaned using method B.

Pickle with a solution containing 5 to 10 weight percent inhibited
sulfuric acid until all scale and rust are removed (pickling times of 15
to 20 minutes are normal). Heat and maintain pickling solution between
160^0^F and 180^0^F.

Pump solution through pipe or immerse in a pickling tank. Immediately
flush with clean water followed by a hot water rinse containing one half
ounce per gallon of sodium carbonate (Na~2~CO~3~) or tri-sodium
phosphate (TSP \-- Na~3~PO~4~).

Flush with rust inhibitor consisting of 0.5% sodium nitrite (NaNO~2~),
0.25% disodium phosphate (Na~2~HPO~4~) and 0.25% monosodium phosphate
(NaH~2~PO~4~). Dry to conform to system requirements.

**Methods F-1 Through 13, Use of Acid for Descaling or Cleaning
Stainless Steel**

#### **General**

Descaling is the removal of heavy, tightly adherent oxide films
resulting from hot-forming, heat treatment, welding and other
high-temperature operations. Descaling methods are outlined in Table 2,
Part I. Cleaning is the removal of surface contaminants to enhance
appearance and corrosion resistance, and to prevent the contamination of
product. Cleaning methods are outlined in Table 2, Parts II and III.
Passivation is generally not needed except in cases where the material
will not be exposed to air or other oxygen containing environment long
enough to establish a passive film. Cleaning and Passivation methods are
listed in Table 2, Part III.

### Precautions

Exposure to the descaling solutions in Table 2, Part I, for more than 30
minutes must be avoided. Drain and rinse the item and re-apply the
treatment if required. Intermittent scrubbing with a stainless steel or
fiber brush may facilitate the removal of heavy scale.

Use of nitric-hydrofluoric acid solutions on stainless steel may produce
intergranular attack in cases where the metal has been sensitized by
welding or improper heat treatment. This can lead to stress corrosion
cracking under service conditions, and is not recommended. In the case
of weldments, only those of the low carbon and stabilized grades may be
safely treated with these solutions.

Hardenable 400 Series, managing, and precipitation hardening alloys in
the hardened condition are subject to intergranular attack and hydrogen
embrittlement when exposed to acids. Use mechanical or other chemical
methods whenever possible. If acid treatment is unavoidable, parts shall
be heated to 250 - 300^0^F for 24 hours to drive off hydrogen.

Severe pitting may result from prolonged exposure to acid solutions if
the solution becomes depleted or if the concentration of metallic salts
becomes too high as a result of prolonged use of the solution. For the
methods in Table 2, part I, limit dissolved iron concentration to 5
weight %. Limit the concentration of dissolved iron to 2 weight % for
all other methods listed in Table 2.

### Method for Using Acid Solutions to Clean and Descale Stainless Steel

Acid treatments are not effective for removal of greases, oils, and
waxes. Surfaces should be pre-cleaned using procedure B if these
contaminants are present.

Select appropriate treatment from Table 2. Total immersion is the
preferred method of application, but the acid solution may be circulated
around or through the item, or the item may be swabbed or sprayed so
that all surfaces receive the required treatment.

All items exposed to acid solutions must be thoroughly rinsed at the
completion of the treatment. To minimize staining, the item must not be
allowed to dry between steps. If necessary, a neutralizer solution may
be used, followed by a final hot water rinse. Final rinse water shall
contain less than 50 ppm chlorides.

Items are to be thoroughly dried after final rinsing.

# APPENDIX L -- BURIED PROCESS PIPE

## SPECIAL CONSIDERATIONS FOR BURIED PROCESS PIPE

Engineering and Construction must consider the following factors to
assure safe operation of a buried piping system:

A.  The selection of the proper pipe material, coating and lining and
    their compatibility with soil and fluid (input from Materials
    Engineer, Vendor and past practice).

```{=html}
<!-- -->
```
E.  The judicious routing of the pipe to minimize natural risks such as
    soil settlement, flood or frost (input from Geotechnical Engineer).

F.  The structural design of the piping system (further discussed in
    this Appendix).

G.  The proper trench preparation and pipe laying (further discussed in
    this Appendix).

H.  The joining method and the quality of fabrication, examination and
    pressure testing which must comply with ASME B31.3 if the piping is
    part of a process system.

I.  The operation, periodic inspection and maintenance of the system.

J.  The use of line markers, sufficient ground cover and controls to
    avoid excavation damage.

## DESIGN OF BURIED PROCESS PIPE

LOADS ON BURIED PIPE

Soil and Surface loads consist of Internal Pressure, Restrained Thermal
Growth or Contraction, Soil Settlement, Waterhammer, and Seismic (wave
passage and differential movements) as applicable.

Design guidance for buried steel pipe may be found in "Design of Buried
Steel Pipe,"
([www.americanlifelinesalliance.org](../www.americanlifelinesalliance.org)).

# APPENDIX M -- Mitered Joints

The equations provided below may be used to determine the maximum
allowable internal pressure for mitered bends using the methods
prescribed by ASME B31.3 paragraph 304.2.3. The designer performing
these calculations should review the B31.3 Code to ensure he understands
all the required details.

NOTE: Mathcad shells for performing these calculations for maximum
internal pressure in single and multiple miter bends are available from
the ESM Mechanical POC.

Step 1

Determine the total mechanical allowance (c) including the erosion and
corrosion for the system in inches.

Step 2

Determine the material allowable stress (S) at the design temperature
from Appendix A, B31.3 in psi.

Step 3

Determine the joint quality factor (E) from Appendix A, B31.3. For
seamless pipe, E=1.

Step 4

Determine the outer diameter (D) and nominal wall thickness (T~nom~) of
the mitered pipe.

Step 5

Determine the geometric design configuration data: R~1~ is the radius of
curvature measured to the centerline of the pipe, θ is the angle of the
mitered cut in degrees. See B31.3 Figure 304.2.3 for nomenclature. R~1~
shall not be less than that calculated be equation M-1.

$R_{1} = \frac{A\ }{\text{tan}\ \theta} + \frac{D}{2}$ (M-1)

where A has the following empirical values:

  ----------------------------------- -----------------------------------
  **(T-c), in.**                      **A**

  ≤0.5                                1.0

  0.5\<(T-c)\<0.88                    2(T-c)

  ≥0.88                               \[2(T-c)/3\]+1.17
  ----------------------------------- -----------------------------------

Step 6

Calculate the minimum pipe wall thickness (nominal thickness minus mill
tolerance).

T=0.875T~nom~ (M-2)

Step 7

Calculate the mean radius of the pipe using the nominal wall thickness.

$r_{2} = \frac{D - T_{\text{nom}}}{2}$ (M-3)

Step 8

The design pressure for the mitered bend is determined using the
equations provided below.

a.  For multiple mitered bend with θ ≤ 22.5 °, P~m~ is the minimum of
    the equations M-4 and M-5:

> $P_{m} = \frac{\text{SE}(T - c)}{r_{2}}\left( \frac{T - c}{(T - c)\  + \ 0\text{.}\text{643}\ \text{tanθ}\sqrt{r_{2}(T - c)}} \right)$
> (M-4)
>
> $P_{m} = \frac{\text{SE}(T - c)}{r_{2}}\left( \frac{R_{1} - r_{2}}{R_{1} - 0\text{.}5\ r_{2}} \right)$
> (M-5)

b.  For single mitered bends with θ ≤ 22.5 °, use equation M-4.
    Otherwise, P~m~ is given by equation M-6.

> $P_{m} = \frac{\text{SE}(T - c)}{r_{2}}\left( \frac{T - c}{(T - c) + 1\text{.}\text{25}\ \text{tanθ}\ \sqrt{r_{2}(T - c)}} \right)$
> (M-6)

Step 9

The miter pipe wall thickness (T) shall extend not less than a distance
(M) from the insides crotch of the end miter welds. See B31.3 Figure
304.2.3. The length of the taper at the end of the miter pipe may be
included in the distance (M). The required value of (M) is the larger of
M-7 and M-8.

$M = 2\text{.}5(r_{2}T)^{0\text{.}5}$ (M-7)

$M = \text{tanθ}\ (R_{1} - r_{2})$ (M-8)

# APPENDIX N -- BRANCH CONNECTIONS

The equations provided below may be used to determine the reinforcement
requirements for a set-on branch connection using the methods prescribed
by ASME B31.3 paragraph 304.3.3. The acceptable details that can be used
with these equations are shown in figures 328.5.4D(1), (3), and (5). The
equations below are based on no reinforcement pad at the branch
connections. The equations are used to determine the requirements for
additional reinforcement. The designer performing these calculations
should review the B31.3 Code to ensure he understands all the required
details. These equations are only applicable when the branch opening in
the header pipe is a projection of the branch pipe inside diameter (i.e.
the branch pipe is set on the header pipe).

NOTE: A Mathcad shell for calculations of reinforcement requirements for
weld branch connections is available from the ESM Mechanical POC.

Step 1

Determine the total mechanical allowance (c) including the erosion and
corrosion for the system in inches and the design pressure in psi.

Step 2

Determine the material allowable stress (S) at the design temperature
from Appendix A, B31.3 in psi.

Step 3

Determine the joint quality factors (E~h~ and E~b~) for the header and
branch pipes from Appendix A, B31.3. For seamless pipe, E=1.

Step 4

Determine the outer diameter (D~h~ and D~b~) and nominal wall thickness
(T~nom,h~ and T~nom,b~) of the header and branch pipe.

Step 5

Determine the smaller angle (β) between the branch and the header. See
Figure 304.3.3 of B31.3.

Step 6

Calculate the required pressure design wall thicknesses using the
equations N-1 and N-2.

$t_{h} = \frac{\text{PD}_{h}}{2(\text{SE} + 0\text{.}\text{4P})}$ (N-1)

$t_{b} = \frac{\text{PD}_{b}}{2(\text{SE} + 0\text{.}\text{4P})}$ (N-2)

Step 7

Calculate the required reinforcement area (A~1~)

A~1~= t~h~d~1~(2-sin β) (N-3)

where d~1~= \[D~b~-2(T~b~-c)\]/ sin β (N-4)

T~b~= 0.875T~nom,b~ (N-5)

Step 8

Calculate the available reinforcement area (A~2~) and (A~3~)

A~2~=(2d~2~-d~1~)(T~h~-t~h~-c) (N-6)

A~3~=2L~4~(T~b~-t~b~-c)/sin β (N-7)

where d~2~=max\[d~1~,(T~b~-c)+(T~h~-c)+d~1~/2\] (N-8)

T~h~=0.875T~nom,h~ (N-9)

L~4~=min\[2.5(T~h~-c), 2.5(T~b~-c)\] (N-10)

Step 9

Calculate the available reinforcement area (A~4~). Area A~4~ is the area
of other metal provided by welds and properly attached reinforcement.
See B31.3 paragraph 328.5.4 for minimum required weld sizes.

Step 10

Calculate the required reinforcement area (A~r~). If A~r~ is positive,
additional reinforcement is required. If A~r~ is less than or equal to
zero, no additional reinforcement is required.

A~r~= A~1~ -- (A~2~ + A~3~ + A~4~) (N-11)

# appendix q - Application of ASME B31.3 to Radioactive Fluids 

The processing of radioactive fluids is performed in many facilities at
LANL. No section of the B31 Code of Pressure Piping addresses
radioactive fluids. When starting to address what code is applicable to
radioactive fluids, many engineers return to the *ASME Boiler and
Pressure Vessel Code, Section III, Rules for the Construction of Nuclear
Power Plant Components*. The scope of Section III is directly applicable
to nuclear power systems and does not apply to processing facilities. To
address the application of radioactive fluids more directly, an inquiry
was sent to the ASME B31 Committee. Interpretation 12-20 clarifying the
use of radioactive fluids in processing facilities is provided below:

Question: In accordance with ASME B31.3-1993 Edition, may the owner
apply B31.3 to piping containing radioactive fluids in a chemical plant?

Reply: Yes, see the Introduction which states that, \"If no section of
the code for pressure piping specifically covers the installation, the
owner at his discretion may select any section determined to be
generally applicable\... It should be noted, however, that requirements
supplementing the Code Section may be necessary to provide safe piping
for the intended application\".

Interpretation 12-20 stresses the need for requirements supplementing
the Code for radioactive fluid services.

Based on Interpretation 12-20, two issues need to be addressed to apply
ASME B31.3 to a radioactive fluid service. First, when will a fluid
service be considered radioactive. Second, what are reasonable
supplementary requirements to apply. The following definition and
requirements are provided to support the use of ASME B31.3 for
radioactive fluid processing. The owner and/or the designer may specify
additional requirements that are deemed necessary to provide a safe
piping system design.

The following definition of a radioactive fluid applies to activities
addressed by this guide:

Radioactive Fluid -- A fluid with sufficient radioactivity that leakage
from a piping system could cause an area to exceed the contamination
limits imposed by LIR 402-700-01, Attachment 1, Chapter 14, Table H-1.

The following minimum additional requirement should be applied to
systems containing radioactive fluids:

1)  Radioactive fluids cannot be excluded from the scope of ASME B31.3.

50) Radioactive fluids cannot be classified as Category D fluid service.

    Additional requirements supplementing the B31.3 Code may be required
    to ensure a safe design for radioactive fluid services.
