- ASTM A234 Espesifikasyon estanda pou ekipman tiyo nan asye kabòn fòje ak asye alyaj pou sèvis modere ak wo-tanperati
Spesifikasyon sa a kouvri asye kabòn fòje ak ekipman asye alyaj nan konstriksyon san pwoblèm ak soude ki kouvri pa dènye revizyon ASME B16.9, B16.11, MSS-SP-79, MSS-SP-83, MSS- SP-95, ak MSS-SP-97. Fittings sa yo se pou itilize nan tiyo presyon ak nan fabrikasyon veso presyon pou sèvis nan tanperati modere ak ki wo. Fittings diferan de estanda ASME ak MSS sa yo dwe founi an akò ak Kondisyon Siplemantè S58 nan Spesifikasyon A960/A960M.
