Here's what I found:
Dedicated to high-pressure hydrogen transmission pipelines, focusing on fracture control and safety in transport. Why Use ASME B31.12?
Hydrogen atoms can diffuse into the crystal lattice of metals (especially high-strength steels), making them brittle and prone to cracking under stress. B31.12 provides material selection criteria and "material performance factors" to mitigate this risk. High Permeability:
Searching for is the first step toward professionalizing your additive manufacturing workflow. Whether you are validating a $500,000 metal printer for a NASA contract or simply ensuring consistent quality for a dental lab, this standard is your blueprint for objectivity.
ASME B31.12 is the dedicated American National Standard covering the design, materials, fabrication, erection, inspection, testing, operation, and maintenance of piping systems for hydrogen service. It applies to both above-ground piping and underground pipelines.
After purchasing, store the PDF on your company network with controlled access. Assign one lead engineer to maintain a "master standards register" that includes ASME B3112, its referenced ASTM documents, and any internal work instructions derived from it.
If you are looking for a specific or a technical comparison between B31.12 and B31.8, let me know and I can provide a breakdown of the differences.
