1. PURPOSE
1.1 This applications guide provides a single-source document that shall be used in selecting the appropriate piping class specification for specific fluid services.
2. scope
2.1 This engineering standard applies to all fluid services and piping class specifications listed in Tables 1, 2, 3, 4, 5, 6, and 7.
2.2 This document shall be used for the selection of piping class specifications for all plants designed globally by Air Products except where project-specific stipulations or design conditions (for example, client or customer specifications, government regulations, and fluid service applications outside the scope of the B31.3 design code) require the use of special project-specific piping class specifications.
2.3 The following Application tables contain specific fluid service applications and recommended piping class specifications for most of the fluid services typically found in air and gas separation plants designed by Air Products. However, there are a number of special applications that the tables do not fully address. The correct selection of piping class specifications for these special applications requires piping expertise, and guidance should be sought from the Mechanical Systems Engineering specialist in the appropriate ET. Application Table 1 – Process Cold Box Application Table 2 – Process Yard Cryogenic Application Table 3 – Process Yard Noncryogenic Application Table 4 – Gaseous Oxygen (GOX) Application Table 5 – Defrost/Disposal, Relief Device Discharge, Seal Gas, and Cold Box Purge Application Table 6 – Electronics Electropolished and Non-electropolished Systems Application Table 7 – Utilities
2.4 Development of special project-specific Piping Class Specifications may result in an overall cost savings for large diameter piping systems where the maximum system design pressure is well below the maximum design pressure listed in the standard piping class specification selected from the application tables.

4. SELECTION OF PIPE CLASS SPECIFICATIONS
4.1 Piping class specifications are named and numbered in accordance with 3PI00001 Section 4.6.5.
4.2 The latest revision of piping class specifications shall be used when selecting materials. However, when an existing design is to be reused, and the piping class specifications used in the existing design are no longer current, Mechanical Systems Engineering shall be consulted as to the acceptability of the outdated specifications.
4.3 Piping class specifications shall be selected for the intended service to suit the following mandatory conditions: Application Fluid Service Pipe Size Range Design Conditions as defined on the flowsheets by design circuit. Considerations shall be given to start-up, shutdown, defrost, and regeneration conditions, and other similar conditions, in defining the worst case for design pressures and temperatures. Corrosion Allowance Internal corrosion of the piping system caused by the fluid (see paragraph 5.3 for the corrosion allowance of standard specifications). Refer to the Corrosion Data Survey – Metals Section and Corrosion Data Survey – Nonmetals Section published by NACE. External corrosion of the piping system caused by atmospheric conditions. Refer to 3EQ68001 for the protection of piping materials under insulation. Availability of Materials—The location of suppliers and fabrication facilities and the availability of materials shall be considered.
4.4 Piping class specification selection shall be made from Tables 1 through 7 of this standard using the lowest suitable pressure rating. The nominal and maximum design pressures listed in Tables 1 through 7 are in bar g with the equivalent pressure in psig and are based on ambient temperatures. For allowable design pressures ratings at elevated temperatures, Table 8 should be consulted. Always verify that the design max/min pressure and temperature ratings are within the service pressure/temperature limits shown in Table 8.
4.5 Cold box piping is typically aluminum because it can be welded directly to aluminum equipment. Aluminum/stainless steel transition joints (TJs) are used to transition from aluminum equipment and piping to stainless steel equipment and piping components. Stainless steel piping should be used directly between stainless steel equipment and components or where required by the service application. Valve and pump chest/box piping shall be stainless steel.
4.6 Piping in gaseous oxygen (GOX) service shall comply with the system design and in-line component material selection requirements of 3PI60001 and 4WPI-60005. All GOX piping system designs shall be reviewed in accordance with Mechanical System’s QMS work instruction MSE04031.
4.7 Piping branch connections in pulsating service (for example, reciprocating compressors) shall be wrought or forged fittings. Unreinforced branch connections are strictly prohibited. Flanges in pulsating service shall be weld neck (WN) or socket weld (SW ≤ 1 ½”). Slip-on (SO) flanges are strictly prohibited.
4.8 3PI50001 defines general requirements and Air Products’ specific requirements for safe and reliable installation and operation of piping systems in hydrogen, carbon monoxide, and syngas production plants.
4.8.1 Additionally, hydrogen damage or high temperature hydrogen attack (HTHA) in plants is caused when hydrogen from the process stream seeps into carbon and low alloy steels at high temperatures. Hydrogen reacts with the carbides in the steel, decarburizing the steel and forming methane gas bubbles at the grain boundaries with no loss of thickness. The methane gas bubbles grow with time and result in micro-cracking. The combination of micro-cracking and decarburization reduces the fracture toughness of steels and leads to major failures. HTHA is triggered in components operating at high temperatures and high hydrogen partial pressure. The Nelson curves, found in API Recommended Practice 941, provide information about safe and unsafe operating environments for components operating in hydrogen environments.
4.9 Table 8 consists of a summary of all Air Products global piping class specifications and lists service, size range, pressure/temperature limits, material, flange ratings, gasket materials, corrosion allowance, and service.
5. PIPING CLASS SPECIFICATION DATA
5.1 Design Code: Air Products uses ASME B31.3 as the piping design code for fluid service applications typically found in petroleum refineries, chemical, semiconductor, and cryogenic plants, and related processing plants and terminals. Additional or supplemental requirements may be added for plants within Europe by the European Pressure Equipment Directive 97/23/EC (PED) and for plants within China by the Chinese Design Code for Industrial Metallic Piping (GB-50316). Other sections of the ASME Piping Code may be required for fluid service applications outside the scope of the B31.3 section and, in those cases; special project-specific piping class specifications might be required.
5.2 Materials: Piping class specifications typically contain three materials sections. Each section is comprehensive in scope and is meant to be used in its entirety. Combining portions of the individual sections is prohibited.Section A contains material commonly used in countries outside of the European Community and the People’s Republic of China. Section E contains material required to meet the requirements of the European Pressure Equipment Directive (PED) 97/23/EC for plants to be commissioned in the European Community and those countries that have adopted the PED. Section C contains material to be used only in the People’s Republic of China (PRC). Some clients and countries might require the use of other piping design codes and, in those cases, special project-specific piping class specifications might be required.
5.3 Corrosion Allowance: An allowance for corrosion is not included in the wall thickness values for aluminium, copper, monel, or stainless steel piping materials. Carbon and low alloy steel piping materials incorporate a 1.3 mm corrosion allowance in the listed wall thickness values where appropriate for the fluid service. Any other corrosion or mechanical allowances required by a project shall require revised wall thickness calculations and special project-specific piping class specifications.
5.4 Maximum Allowable Oxygen Purity: Aluminum piping class specifications include the maximum allowable oxygen purity based on the pressure/purity curve limitations contained in 2S301.
5.5 Service Limitations: Pressure/temperature service limitations are shown on the front page of each piping class specification. Any interpolation between listed pressure/temperature values should be based on the values listed in the applicable referenced code, standard, or specification. For example: For flanges use pressure/temperature rating tables in ASME B16.5 to calculate, by linear interpolation, the intermediate metric values of bar g or °C. Intermediate US customary values of psig or °F may be similarly calculated by using the tables in Annex F.
5.5.1 The minimum design temperature of carbon steel pipe class specifications (-20°C/-4°F) is limited by the materials listed in Section C – “Chinese Materials”. Piping systems constructed using the carbon steel materials listed in Section A – “Non-PED Materials” or Section E – “PED Materials” may be used at a minimum design temperature of -29°C/-20°F.
5.6 Reducers: Size ranges shown for reducers are the larger ends only and do not include nonpreferred sizes (1¼, 2½, 3½, 5, 22, 26, 28, 32, 34, 38, 40, 44, and 46 NPS). Nonpreferred sizes are only allowed to step up to the next preferred nominal pipe size.
5.7 Flanges: Only flanges of the lowest applicable flange pressure rating are included in the piping class specification. Equivalent flanges of higher pressure rating are acceptable and should be included in the PDS version of the piping class specification.
5.8 Manual Valves: Manual valves shall be selected from the appropriate table in 4WPI-EW85001 based on the applicable piping class specification.
5.9 Threaded Pipe: Threaded pipe shall have a minimum wall thickness of schedule 80 to maintain mechanical integrity.

1) American non-metallic piping material specifications are listed for reference.
2) See 3EQ10601 for definitions of open and closed loop systems and piping material recommendations.
3) The suitability of 304/316 stainless steel piping materials in water services operating at or above 50°C (122°F) must be verified because of the potential of stress corrosion cracking resulting from a high level of chlorides in the water.

Table 8 Notes:
(1) WCP036—This specification is intended to be used for piping headers on Pressure Swing Adsorber (PSA) skids. These headers are subjected to pressure variations as they transfer gas between PSA vessels. This specification may be used on any piping system with a 0.0 mm (0.00 in) corrosion allowance and exposed to pressure variations and operating within the given limits of pressure and maximum cycles (see specification front sheet). The scope of this specification does not include temperature fluctuations and, therefore, is not applicable to Temperature Swing Adsorption (TSA) systems.
(2) WCP036A—This specification is intended to be used for piping directly attached to Pressure Swing Adsorber (PSA) vessels. This piping is subjected to the same pressure variations as the PSA vessel to which it is attached. This specification may be used on any piping system with a 0.0 mm (0.00 in) corrosion allowance and exposed to pressure variations and operating within the limits of pressure and maximum cycles (see specification front sheet). The scope of this specification does not include temperature fluctuations and, therefore, is not applicable to Temperature Swing Adsorption (TSA) systems.
(3) See “Table 9 – Global Gasket Material Purchase Specifications” for description of gaskets, Air Products approved Pressure-Temperature (P-T) application limits, and approved supplier and style configurations.
(4) The following global pipe class specifications (4WPIC… documents) have been excluded from this summary because of their country specific or service type specific nature. These documents should not be used unless specifically approved by the applicable Mechanical Systems Engineering Lead Engineer.
- a) Document numbers 4WPICJ… ; where J = Japanese Design Code or National Authority specific.
- b) Document numbers 4WPICWMA… ; M = Piping Material and A = Electronic Chemicals (Ashland) specific.
- c) Documents numbers 4WPI- CWIU001, CWPE010, CWPE010A, CWPE010B, CWST010, and CWST010A which are for Electronic Chemicals (Ashland) use only.
(5) The following American pipe class specifications (4WPICA… documents) have been included in this summary for reference because no global documents in these materials currently exist.
- a) Copper Tube specifications AKC020 and AKC030
- b) High Density Polyethylene (HDPE) specifications APU007 and APU010

Notes:
- “Air Products Specification Approved P-T Limits” may be higher or lower than the manufacture’s listed P-T limits because the Air Products limits are based on 1) Air Product’s historical successful field operating gasket usage up to the specified values, and 2) consultations with the gasket manufacture’s Engineering staff whenever the Air Product’s usage limits exceeded the manufacture’s published gasket application limits.
- Flat ring gaskets are limited to ASME Class 150 and Class 300 flanges except as noted.
- Low stress spiral-wound gaskets are limited to ASME Class 150 and Class 300 flanges.
- Oxygen service pressure and temperature limits are 40 barg (580 psig) and 60C (140F)
