Stringent fabrication and quality control measures are mandated. The code includes specific requirements for welding, brazing, and heat treatment, including the qualification of welding procedures and personnel. It details rigorous non-destructive examination (NDE) requirements, including acceptance criteria for volumetric and surface examinations. For example, for welds in certain thickness ranges, it provides specific limits for flaw indications based on imaging. The standard also provides guidance on inspection, examination, and testing procedures, as well as operation and maintenance practices to ensure long-term integrity.

The American Society of Mechanical Engineers (ASME) publishes various codes and standards for designing, fabricating, and inspecting piping systems. One such standard is ASME B31.12, which specifically addresses the design, fabrication, and inspection of hydrogen Piping and Pipelines. asme b 31.12 pdf
