Comprehensive Guide to ASME B31.12 PDF: Hydrogen Piping and Pipelines Standards
is the international standard governing the design, materials, fabrication, assembly, inspection, testing, operation, and maintenance of hydrogen piping and pipelines. It is part of the ASME B31 Code for Pressure Piping. Key Applications Gaseous Hydrogen Service: Piping and pipelines. Liquid Hydrogen Service: Piping only.
Only specific carbon steels and alloys are permitted to prevent embrittlement.
Once these changes are fully implemented, ASME B31.12 will be retired, and the regulations will be integrated into the primary piping codes. How to Obtain the ASME B31.12 PDF asme b 31.12 pdf
