Maximum Allowable Working Pressure for Standard Pressure

				  shall be determined in accordance with the applicable provisions of the edition
				  of the ASME code or the API-ASME code under which they were constructed and
				  stamped.

Maximum Allowable Working Pressure for Nonstandard Pressure
				  Vessels, except as provided in 004 of this chapter.
A. The maximum allowable working pressure of
				a nonstandard pressure vessel shall be determined by the strength of the
				weakest course computed from the thickness of the plate, the tensile strength
				of the plate, the efficiency of the longitudinal joint, the inside diameter of
				the course and the factor of safety set by these rules.
TStE / RFS = maximum allowable working pressure (MAWP), psig
				  where:
TS = specified minimum tensile strength of shell plate
				  material, psi. (When the tensile strength of carbon steel plate is not known,
				  it may be taken as 55,000 psi for temperatures not exceeding 650 degrees
				  Fahrenheit. For other materials use the lowest stress values for that material
				  from ASME Section VIII.)
t = minimum thickness of shell plate of weakest course,
				  inches.
E = efficiency of longitudinal joint depending upon
				  construction. Use the following values: for riveted joints - calculated riveted
				  efficiency; for fusion-welded and brazed joints:
single lap weld
								......................................................
40%
double lap weld
								....................................................
50%
single butt weld
								.....................................................
60%
double butt weld or forge weld
								..............................
70%
brazed steel
								..........................................................
80%
R = inside radius of weakest course of shell (inches)
				  provided the thickness does not exceed 10 percent of the radius shall be
				  used.
FS = factor of safety allowed by these
				  rules.
B. The minimum factor
				of safety shall in no case be less than 5 for existing installations. The
				working pressure shall be decreased when deemed necessary by the inspector to
				insure the operation of the vessel within safe limits. The condition of the
				vessel and the particular service to which it is subject will be the
				determining factors.
C. The maximum
				allowable working pressure permitted for formed heads under pressure shall be
				determined by using the appropriate formulas from ASME code, and the tensile
				strength and factors of safety given in 002 and 003(A) of this
				Chapter.
D. The maximum allowable
				working pressure for nonstandard pressure vessels subjected to external
				pressure shall be determined by the rules of the appropriate ASME
				code.

Pressure vessels that were not ASME code stamped but which
				  were constructed of known materials and were designed and constructed in
				  accordance with sound engineering standards, formulas and practices that
				  provide safety equivalent to the intent of the code shall be calculated on the
				  same basis as used in the original design.

Where, in the opinion of the inspector, as the result of
				  conditions disclosed at the time of inspection, it may be necessary to remove

				  the vessel not normally visible, the owner or user shall remove such material
				  to permit proper inspection and to determine remaining
				  thickness.

Each pressure vessel shall be provided with pressure relief
				  devices, indicating and controlling devices as necessary to protect against
				  overpressure. The devices shall be so constructed, located and installed that
				  they cannot readily be rendered inoperative. The relieving capacity of such
				  pressure relief device shall be adequate to prevent a rise in pressure in the
				  vessel of more than 10% or 3 psig, whichever is greater, above the maximum
				  allowable working pressure except when multiple relieving devices are provided,
				  they shall prevent the pressure from rising more than 16% or 4 psig, whichever
				  is greater, above the maximum allowable working pressure. When multiple
				  pressure relieving devices are provided, at least one device shall be set at or
				  below the maximum allowable working pressure and the additional devices shall
				  be set no higher than 105% of the maximum allowable working pressure. When an
				  additional hazard is involved due to fire or other unexpected sources of
				  external heat, the pressure relief devices shall meet the requirements of ASME
				  code.
