Before the publication of B31.12, engineers often had to adapt codes meant for natural gas (like ASME B31.8) or process piping (ASME B31.3) for hydrogen use. ASME B31.12 bridges the gap, offering specific guidelines tailored to the unique properties of hydrogen.
Because hydrogen molecules are so small, they can leak through seals, threads, and micro-fissures that would contain natural gas. The code mandates specific joint designs and testing protocols to ensure leak-tightness. asme b 31.12 pdf
