Pabrikan
Fitting pipa baja karbon ASTM A234 bisa digawe saka pipa sing mulus, pipa sing dilas utawa piring kanthi mbentuk operasi pencet, piercing, extruding, mlengkung, welding fusi, mesin, utawa kanthi kombinasi loro utawa luwih operasi kasebut.Kabeh welds kalebu welds ing produk tubular saka kang fittings digawe kudu digawe miturut ASME Section IX.Perawatan panas sawise las ing 1100 nganti 1250 ° F [595 nganti 675 ° C] lan pemeriksaan radiografi kudu ditindakake sawise proses las.
