ASME B31.8 (2018)

ASME B31.8 (2018) governs the design, fabrication, installation, and testing of natural gas pipeline systems. It applies to transmission lines, compressor stations, and distribution networks, including both onshore and offshore infrastructure.

In SDC Verifier, the standard implements pipeline stress checks defined in Chapters 833.1 to 833.6. These cover internal pressure effects, temperature-induced stresses, and combined loads with stress intensification factors (SIFs) for welded elbows, miters, and bends.

SDC Verifier automatically considers factors such as pipe restraint conditions, thermal expansion, material properties, and design class. Checks are performed based on user-defined geometry and operating conditions — ensuring compliance with location-specific and safety-critical pressure limits.
