ASTM A302 GR.C Mn-Mo-Ni Alloy Pressure Vessel pereti maitai

Ko te ASTM A302 Koeke C he konupora-molybdenum-nickel alloy boiler pereti rino. Ko te maitai o A302 Grade C ka patua, ka rite ki nga whakaritenga rahi witi pai. Ko te paraharaha rino paraharaha A203 Grade C ka tukuna ki te whakamatautau i te raruraru ki te whakatau i te kaha o te kaha, te kaha o te tuku, me te roa. A, no te okeoke SA302 Kōeke C i raro i te aratohu maitai NACE MR0175, whakamātautau HIC, SCC, SSC whakamātautau me mahi i roto i to tatou taiwhanga mira mo gurantee SA302 Grade C taonga maitai. Ko etahi atu whakamatautau hangarau, penei i te PWHT, DWTT, Ko te whakamatautau whakamaarama teitei ka tohua e nga kaiwhakamahi mutunga mena ka tono.
Matotoru: 6MM ki te 300MM,
Whānui: 1500mm ki te 4050mm,
Te roa: 3000mm ki te 15000mm
