A key reason for the Code's importance is its stricter approach to hydrogen service compared to general process piping. For instance, a study comparing the structural impact of the material performance factor showed that hydrogen-specific codes impose more conservative design pressures due to the risk of hydrogen embrittlement. This is further reinforced by Code Case 218, which justified eliminating certain material performance factors due to the costs and fabrication challenges they introduced. asme b 3112 pdf

The ASME B31.12 standard provides specific requirements to address the unique challenges of hydrogen, particularly and high-pressure fatigue. It covers both gaseous and liquid hydrogen service and applies up to the joint connecting to pressure vessels or equipment. The code is organized into three main parts: The ASME B31

Flanged joints must use specialized, low-leakage gaskets (such as spiral-wound or grooved metal gaskets) capable of maintaining a tight seal under thermal cycling. Inspection, Testing, and Commissioning This is further reinforced by Code Case 218,
