ASME B31.3 - Process Piping: 2024 [secured pdf]

ASME B31.3-2024 – Process Piping [secured pdf]

It contains requirements for piping typically found in petroleum refineries; chemical, pharmaceutical, hydrogen, textile, paper and pulp, power generation, semiconductor, and cryogenic plants; and related processing plants and terminals. It covers materials and components, design, fabrication, assembly, erection, examination, inspection, and testing of piping.

This Code applies to piping for all fluids including: raw, intermediate, and finished chemicals, petroleum products, gas, steam, air and water, fluidized solids, refrigerants, cryogenic fluids. Also included is piping that interconnects pieces or stages within a packaged equipment assembly.

Key changes to this revision include:

• Added a recommendation to consult the Energy Institute Publication Guidelines for the management of flexible hose assemblies.
• Changed Sustained Stress Indices from using 0.75i and 1.0 as default values in the absence of more applicable data
• Listed Fittings (Table 326.1) changes include the addition of press-connect fittings, globe valves (API 623), high-pressure butterfly valves (MSS SP-68) and deleted metal hose standard BS 6501-1.
• Backing Gas (para. 328.5.1) states that the acceptable level of discoloration should be described in the engineering design.
• Bolt Tightening (para. 335.2.2) states that the bolt stress is not limited to the allowable stress when tightening bolts.
• Revised examination requirements and acceptance criteria for the Surfaces on Pressure-Containing Components Where Attachment Welds Have Been Removed.
• Leak Testing Mechanical Joints (para. 345.2.3) permits that all mechanical joints that have been leak tested to be taken apart and reassembled without having to be subjected to an additional leak test
• Additional acceptable procedures for Joints in Thermoplastic Piping: Solvent Cemented Joints (para. A328.5.3), Heat Fusion Joints (para. A328.5.4), and Electrofusion Joints (para. A328.5.5).
• Removed the requirement that branch connection fitting to header welds be radiographically or ultrasonically examined in Category M Fluid Service.
• Added specific requirements for the designer to report to the owner within the Written Report (para. K300).
• Change to the Allowable Stresses (para. K302.3.2, Appendix K) in High Pressure Piping to align ASME B31.3 Chapter IX with the 2023 edition of ASME BPV Section VIII Division 3.
• Lower Temperature Limit for ASTM A105 Flanges (para. F323.2.2) includes recommendations that the designer to consider additional material requirements for ASTM A105, Class 150 and 300 weld neck flanges for temperatures colder than -18°C (0°F).
• Updated recommendations to European Pressure Equipment Directive (para N301) regarding the use of ASME B31.3 in jurisdictions governed by the Pressure Equipment Directive.
