Providing clearer guidance on the use of composite materials, polymer liners, and Fiber Reinforced Polymers (FRP) for hydrogen service.
Hydrogen is the smallest and lightest molecule in the universe. This physical property creates specific risks that ASME B31.12 is designed to mitigate:
The code heavily regulates what materials can be used. High-strength carbon steels are highly susceptible to embrittlement, so the code mandates low-strength, high-ductility steels. For high-pressure or high-purity hydrogen, austenitic stainless steels (such as 316/316L) are preferred due to their excellent resistance to hydrogen degradation. Design Material Performance Options
Enhanced non-destructive examination (NDE), including 100% radiography (RT) or ultrasonic testing (UT) for critical joints. Material Recommendations in ASME B31.12
