Tsim
ASTM A234 carbon steel yeeb nkab fittings yuav ua tau los ntawm seamless kav, welded kav los yog daim hlau los ntawm shaping kev khiav hauj lwm ntawm nias, tho, extruding, dabtsi yog khoov, fusion vuam, machining, los yog ua ke ntawm ob los yog ntau tshaj cov kev khiav hauj lwm.Tag nrho cov welds suav nrog cov welds hauv cov khoom siv tubular los ntawm cov khoom fittings yuav tsum tau ua raws li ASME Tshooj IX.Kev kho cua sov tom qab vuam ntawm 1100 txog 1250 ° F [595 txog 675 ° C] thiab kev kuaj hluav taws xob yuav tsum tau ua tom qab txheej txheem vuam.
