ASME · American Society of Mechanical Engineers
The body behind the B31 pressure-piping code family that governs how North American liquid-cooling loops are designed, welded, inspected, and pressure-tested.
Current numbers
1.5×design pressure for the hydrostatic acceptance hold on the isolated pipe scope, per the governing code (ASME B31.x / EN 13480) — assembled-loop components (CDU, hoses, QDs) are proven to their own MAWP-derived limits, never a blanket multiplier
