Detailed procedures (WPS) are required, with stringent Nondestructive Examination (NDE) requirements, including radiographic or ultrasonic testing. 3. Inspection and Testing Visual Inspection: Extensive visual check of all welds.

B31.12 limits the use of certain materials and requires testing for susceptibility to embrittlement, particularly for high-pressure applications.

Safety in hydrogen service relies heavily on verification. ASME B31.12 mandates rigorous quality control steps before a system can be commissioned: For hydrogen piping systems in industrial facilities, Part

While earlier hydrogen projects used ASME B31.3 or B31.8, B31.12 was developed to close the gaps in those codes regarding hydrogen behavior. However, the industry is evolving.

Hydrogen atoms are incredibly small. They can diffuse into the crystalline lattice of metals, particularly high-strength steels. This causes the material to lose ductility, leading to cracking and catastrophic brittle failure under stress.

Catastrophic, brittle structural failure well below the material's theoretical yield strength. Part PL: Pipelines
