To combat this, ASME B31.12 provides strict, data-driven mandates on material selection. It guides engineers toward materials that are less susceptible to embrittlement, often requiring lower-strength steels that retain their toughness, or specific stainless steel alloys. Furthermore, the code establishes rigorous design factors that reduce allowable stress levels in the pipeline walls, adding a thicker margin of safety compared to standard natural gas lines. Safety, Welding, and Inspection Overview ASME B31

In conclusion, ASME B31.12 is a critical standard for ensuring the safe and reliable transportation of hydrogen through pipelines. The PDF version of the standard provides a comprehensive guide for designers, constructors, and inspectors involved in hydrogen pipeline projects. By accessing and utilizing ASME B31.12, pipeline operators can minimize risks, ensure public safety, and protect the environment. To combat this, ASME B31

Perhaps the most critical engineering hurdle addressed by ASME B31.12 is hydrogen embrittlement. When hydrogen gas is kept under high pressure, atomic hydrogen can penetrate high-strength steels and other alloys. This diffusion reduces the ductility and fracture toughness of the metal, making it brittle and highly susceptible to catastrophic, unexpected cracking and failure.
