- Manyleb Safonol ASTM A234 ar gyfer Ffitiadau Pibellau Dur Carbon Gyr a Dur aloi ar gyfer Gwasanaeth Cymedrol a Thymheredd Uchel
Mae'r fanyleb hon yn ymdrin â gosodiadau dur carbon gyr a dur aloi o wneuthuriad di-dor a weldio a gwmpesir gan yr adolygiad diweddaraf o ASME B16.9, B16.11, MSS-SP{5}}, MSS-SP-83, MSS- SP-95, ac MSS-SP-97. Mae'r ffitiadau hyn i'w defnyddio mewn pibellau pwysedd ac mewn gwneuthuriad llestr gwasgedd i'w gwasanaethu ar dymheredd cymedrol ac uchel. Rhaid i ffitiadau sy'n wahanol i'r safonau ASME ac MSS hyn gael eu dodrefnu yn unol â Gofyniad Atodol S58 o Fanyleb A960/A960M.
