⛽ ASME B31.12 (Hydrogen Embrittlement Derating, Material Performance Factor Hf 0.60-0.80)

ASME B31.12 Hydrogen Pipeline Calculator

Size high-pressure gaseous hydrogen cross-country transmission pipelines under ASME B31.12 (Hydrogen Piping and Pipelines): calculate hydrogen embrittlement material performance derating factor ($H_f ext{ } 0.60 ext{ to }0.80$ for API 5L X52 through X70 carbon steels), determine required wall thickness ($t$), allowable operating pressure ($MAOP ext{ up to }100 ext{ Bar}$), and pipeline EPC profits.
