Patent Abstract:
A method for selecting a parts kit detail for the installation of a pressure transducer on a container such as a pipeline or a vessel, the container for containing a fluid material, the method including two steps. The first step is to establish at least two different installation categories, each such different installation category being defined by the properties of the fluid material. The second step is to establish at least two different parts kit details, at least two of such different parts kit details being applicable to the different installation categories.

Full Description:
This application claims the benefit of provisional application Ser. No. 60/034,820 filed Dec. 19, 1996. 
    
    
     Most modern chemical processing facilities use numerous pressure transducers to determine pressure and flow rate of fluids being conveyed in pipe lines. In addition, such facilities use pressure transducers to determine pressure and level in process vessels. 
     Safety considerations require that the pressure transducers be installed using materials of construction and of a design which will safely withstand exposure to the material contained in the process pipe or vessel at the temperature and pressure of the material. Safety considerations also may require that the pressure transducers be installed using flush and drain flanges or other means that allow safe venting and flushing of the material before the transducer is disconnected for service or replacement. 
     When an instrument engineer needs to specify the kit of parts necessary to install a pressure transducer on a pipe line or vessel, the engineer will design and specify any necessary pipe manifold, block valves, flanges and other parts depending on the properties of the material, such as its pressure, temperature, toxicity as well as the tendency of the material for clogging or plugging passageways. In addition, the physical orientation of the pipe (horizontal or vertical) or vessel will be taken into account. 
     For a modern chemical processing facility, the instrument engineer will repeat this process for the many pressure transducers that will be installed in the facility. When the instrument engineer is finished, a number of parts kits will have been designed and specified which exactly, in theory, meet the needs of each application. However, since each application is custom designed, the overall process is relatively expensive. 
     It would be an advance in the art of designing and specifying such parts kits if a method could be developed which standardized the process, to at least some degree, and therefore reduced its cost and resulted in a limited number of standardized designs rather than an almost endless variety of custom designs. 
    
    
     The instant invention is a method for selecting a parts kit in a more standardized manner and at a reduced cost. More specifically, the instant invention is a method for selecting a parts kit detail for the installation of a pressure transducer on a container such as a pipe line or a vessel, the container for containing a fluid material, the method comprising the steps of: establishing at least two different installation categories, each such different installation category being defined by the properties of the fluid material; establishing at least two different parts kit details, at least two of such different parts kit details being applicable to a different installation category; and determining the installation category for the fluid material so that at least one parts kit detail can be selected for the installation.

     Each category is defined by the properties of the material in the pipe line or vessel such as its temperature, pressure, toxicity or other safety hazard, and its tendency to plug passageways through which it is flowed. 
     Of course, the scheme shown in FIG. 13 is but one example of any number of possible alternatives. What is critical in the instant invention is that at least two such categories must be defined by the properties of the material. The material can be any fluid such as a gas or a liquid. For example, the material can be steam or water. In its full scope, the material can be any of the myriad of chemicals and mixtures of chemicals of a modern chemical process facility, including a refinery or a pipeline facility, including gases, liquids and slurries.

     FIGS. 1-12 show an exemplary sampling of these details. A parts kit detail is a drawing or a list of the primary parts needed to install a pressure responsive instrument on a pipe line or on a vessel according to a standardized design applicable to at least one installation category. Preferably, an individual parts kit detail is applicable to only one installation category. For example, parts kit detail number 3351-00 from Table II is applicable only to category 1. However, it will be noted that some parts kit details, such as 4300-01 from Table II, are applicable to more than one installation category. 
     When more than one parts kit detail is applicable to an installation category for a specific application, the selection of which detail should be used will depend on a number of factors. For example, on a horizontal pipe wherein the transducer will be supported, an orifice plate, venturi or wedge meter system can be used. Each such system has its advantages and disadvantages as is well known in the art. Thus, the instrument engineer selects the parts kit detail best suited to the application rather than custom designing a kit which theoretically perfectly meets the needs of the application. Almost every installation of a pressure transducer for flow, pressure and level measurement in a modern chemical process facility can be made by using the most appropriate parts kit detail for that installation. The result is a systematic approach that avoids a custom installation for each such application. 
     Pressure transducers are available from many suppliers, such as the Models 1151 and 3051 pressure and differential pressure transmitters from the Rosemount Measurement Division of Fisher-Rosemount, Eden Prairie, USA, which read absolute pressure (AP) or differential pressure (DP) in most any pressure range encountered in a modern chemical processing facility, including a refinery and a pipeline facility. 
     Referring now to FIG. 1, therein is shown a parts kit detail for an orifice plate  20  differential pressure transducer  21  on a horizontal pipe line  22  for installation category 1. The orifice plate  20  is positioned between a pair of pipe line flanges  23 . The pipe line flanges  23  are bored therethrough by passageways  24 . Eccentric adapters  25  are to be socket welded into the passageways  24 . Rotation of the eccentric adapters  25  about the dotted line axis shown provides a fifty four millimeter spacing between the mouths of the adapters  25  even if the spacing between the passageways  24  varies somewhat from this spacing. Tailpieces  26  are to be socket welded into the adapters  25 . Root valves  27  are to be bolted to the tailpieces  26 . A bypass manifold  28  is positioned between the valves  27  and the transducer  21 . The bypass manifold  28  contains an internal flow control valve, not shown, which is actuated by a handle  29  to zero the transducer  21  when it is installed as indicated in FIG.  1 . The transducer  21  has vent ports  30 , used to de-pressure the transmitter  21  to the atmosphere, which are shown plugged. 
     It should be understood that the use of the above described eccentric adapters is not critical in the instant invention. However, reference is made to International Application No. PCT/US 96/20387, since this application relates to such adapters and other hardware described this application. 
     Referring now to FIG. 2, therein is shown a parts kit detail similar to that shown in FIG. 1 but for installation category  2 . The elements shown in FIG. 2 which are the same as FIG. 1 have the same reference numbers. A rear mounted manifold  31  is added to the kit. The rear mounted manifold contains two shut off valves, not shown, which are actuated by a handle  32  and a handle  33 . The rear mounted manifold  31  has flushing ports  34  which are shown plugged. However, when the rear mounted manifold is installed as indicated in FIG. 2, it is intended that vent collection tubes, not shown, will be connected to the flushing ports  34  so that actuation of the handles  29 ,  32  and  33  (and closing valves  27 ) will facilitate flushing and de-pressuring the transducer  21  before it is removed for service or replacement. 
     Referring now to FIG. 3, therein is shown a parts kit detail similar to that shown in FIG. 1 but for installation category 3. The elements shown in FIG. 3 which are the same as FIG. 1 have the same reference numbers. No bypass manifold  28  is used. Instead, a rear mounted three-valve manifold  35  is used. The rear mounted three-valve manifold  35  contains an internal flow control valve, not shown, which is actuated by handle  36  to zero the transducer  21 . The bypass rear mounted manifold  35  has flushing ports  37  which are shown plugged. However, when the bypass rear mounted manifold  35  is installed as indicated in FIG. 3, it is intended that vent collection tubes, not shown, will be connected to the flushing ports  37  so that actuation of handles  38  and  39  (and closing valves  27 ) will facilitate clearing the transducer  21  before it is removed for service or replacement. 
     Referring now to FIG. 4, therein is shown a parts kit detail for a level measurement pressure transducer  41  on a vessel  40  for installation category 2, 4 and 5. A process isolation valve  42  is shown connected to a nozzle  43  of the vessel  40 . A flushing flange  44  is positioned between the transducer  41  and the valve  42 . Flushing valves  45  facilitate the flushing away of solids that may have plugged the valve  42 , the flange  44  or the transducer  41 . 
     Referring now to FIG. 5, therein is shown a parts kit detail similar, in some respects, to that shown in FIG. 1 but for installation category 5A. The elements shown in FIG. which are the same as FIG. 1 have the same reference numbers. A pipe manifold  30  assembly  46  is positioned between the manifold  28  and the transducer  21 . A support assembly  47  supports one end of the pipe manifold assembly  46 . The pipes of the pipe manifold assembly  46  dip downward toward the supported end  48  of the pipe manifold assembly  46  so that the hot vapors of the material can condense and collect near the supported end  48  of the pipe manifold assembly  46  to help keep the transducer  21  cooler than if it were exposed directly to the hot vapors of the material. A rear mounted three-valve manifold  35  has the same function and reference number as the rear mounted three-valve manifold of FIG.  3 . 
     Referring now to FIG. 6, therein is shown a parts kit detail similar, in some respects, to that shown in FIG. 1 but for installation category 5B. The elements shown in FIG. 6 which are the same as FIG. 1 have the same reference numbers. It will be noted that the valves  27  are welded into a valve pipe manifold assembly  49  which includes vent valves  50  and a supported end  51 . A support assembly  52  supports the supported end  51  of the valve pipe manifold assembly  49 . A bypass manifold  53  is positioned between the transducer  21  and the bypass manifold  53 . The bypass manifold  53  contains an internal flow control valve, not shown, which is actuated by handle  54  used to zero the transducer  21 . The pipes of the valve pipe manifold assembly  49  dip downward toward the supported end  51  of the valve pipe manifold assembly  49  so that the hot vapors of the material can condense and collect near the supported end  51  of the valve pipe manifold assembly  49  to keep the transducer  21  cooler than if it were exposed directly to the hot vapors of the material. 
     Referring now to FIG. 7, therein is shown a parts kit detail similar to that shown in FIG. 5 but for installation category 6A. The elements shown in FIG. 7 which are the same as FIG. 5 have the same reference numbers. The kit shown in FIG. 7 has a pipe manifold assembly  46   a  and a supported end  48   a . The pipe manifold assembly  46   a  is similar to the pipe manifold assembly  46  of FIG. 5 except that the pipes of the pipe manifold assembly  46   a  are longer than the pipes of the pipe manifold assembly  46  of FIG.  5 . This longer length helps to better isolate the transducer  21  from the hot vapors of material. 
     Referring now to FIG. 8, therein is shown a parts kit detail similar to that shown in FIG. 6 but for installation category  6 B. The elements shown in FIG. 8 which are the same as FIG. 6 have the same reference numbers. The kit shown in FIG. 8 has a pipe manifold assembly  49   a  and a supported end  51   a . The pipe manifold assembly  49   a  is similar to the pipe manifold assembly  49  of FIG. 5 except that the pipes of the pipe manifold assembly  49   a  are longer that the pipes of the pipe manifold assembly  49  of FIG.  6 . This longer length helps to better isolate the transducer  21  from the hot vapors of material. 
     Referring now to FIG. 9, therein is shown a parts kit detail similar to that shown in FIG. 7 but for installation category 7. The elements shown in FIG. 9 which are the same as FIG. 7 have the same reference numbers. The kit shown in FIG. 9 has a pipe manifold assembly  46   b  and a supported end  48   b . The pipe manifold assembly  46   b  is similar to the pipe manifold assembly  46   a  of FIG. 7 except that the supported end  48   b  is elevated relative to the supported end  48   a  of FIG.  7 . The elevation of the supported end  48   b  helps to keep cryogenic liquids of the material away from the transducer  21  to better protect it from the cold. Instead, the transducer  21  tends to be exposed to vapors of the material which have less heat capacity. 
     Referring now to FIG. 10, therein is shown a parts kit detail for measuring pressure in a pipe line or in a vessel for installation category 8, which includes a pressure transducer  50 . A root valve  51  is positioned between the transducer  50  and a flange  52 . A flush valve  53  is positioned on the other side of the transducer  50 . The arrangement shown in FIG. 10, including the type of valves and welding connections used, facilitates rigorous cleaning of the system and reduces crevasses and pockets where contamination may collect. 
     Referring now to FIG. 11, therein is shown a parts kit detail for measuring pressure in a vessel  54  for installation categories 2, 3, 4, 5A, 5B, 6A, 6B, 7 and 9. The parts kit detail shown in FIG. 11 is similar in some respects to the parts kit detail shown in FIG. 4. A process isolation valve  55  is shown mounted on a nozzle  56  of the vessel  54 . A flushing flange  57  is positioned between a remote pressure sensor assembly  58  and the valve  55 . A support assembly  59  supports a pressure transducer  60 . A capillary tube  61  connects the remote pressure sensor assembly  58  and the transducer  60  and helps to isolate the transducer  60  from the high temperature of the material. Flush valves  62  have the same function as the flush valves  45  of FIG.  4 . 
     Referring now to FIG. 12, therein is shown a parts kit detail similar to that shown in FIG. 2 but for installation category 10. The elements shown in FIG. 12 which are the same as FIG. 2 have the same reference numbers. High pressure shut off valves  61  are used as well as a high pressure rated pressure transducer  62 . A high pressure rated pipe manifold  63  is positioned between the bypass manifold  28  and the transducer  62 . A support assembly  64  supports one end of the pipe manifold  63  as shown. 
     The method of this invention can be implemented by establishing a book of parts kit details, such as are described in Table II, and a means for establishing the different installation categories, such as is shown in FIG.  13  and summarized in Table I. When the installation category is determined, then flow, pressure, or level measurement can be selected. For most all applications there will be at least one parts kit detail that is applicable for the installation and which can be selected. However, it is preferable to incorporate the above described information in computer program for a general purpose digital computer and to add a number of enhancements to such a computer program. 
     The enhancements include the selection of the piping material, assuming a pipe manifold is used. Materials can include carbon steel and various stainless steels such as  316  type stainless steel or HASTELLOY C brand steel. In addition, the weld type, valve selection, bracket selection, flush ring selection, venturi or wedge connection dimensions, bolt selection, valve options, manifold material, alternate impulse line orientation, certification, the material of the eccentric adapters, testing, process flange and connection configuration, special cleaning, flange options for diaphragm seal pressure gauge installation details, painting, winterizing enclosures, additional blind flanges, direct weld valves and mounting bracket sizes for remote seal flush ring pressure details can be specified. 
     When the invention is implemented using a computer as discussed above, then when the instrument engineer has finished answering all of the prompts of the computer program, the program can be written to provide an order number for the kit which will allow a kit supplier to provide all of the parts for the kit, including optional enhancements such as winter enclosures and special painting. In addition, the computer program preferably prints a specification sheet including the price of the kit and the possibility for placing an order for the kit automatically by MODEM over telephone lines.
