ASTM A302 GR.C Mn-Mo-Ni Alloy Pressure Vessel saxan bir ah

ASTM A302 Darajada C waa saxan bir ah oo kuleyliyaha ah ee Manganese-molybdenum-nickel. Birta A302 Fasalka C waa in la dilo waana in ay waafaqaan shuruudaha cabbirka hadhuudhka. Saxanka birta kuleyliyaha ah A203 Fasalka C waa in la mariyaa tijaabada xiisadda si loo go'aamiyo xoogga xajinta, xoogga dhalidda, iyo dhererka. Marka la rogrogayo SA302 Fasalka C ee hoos yimaada hagaha birta NACE MR0175, Imtixaanka HIC, SCC, Imtixaanka SSC waa in lagu sameeyaa shaybaarka-shiidka si loo dammaanad qaado SA302 Grade C hantida birta. Tijaabo kale oo farsamo oo dheeri ah, sida PWHT, DWTT, Tijaabada heerkulka sare waa in ay doortaan isticmaalayaasha dhamaadka haddii ay dalbadaan.
Dhumucda: 6MM ilaa 300MM,
Ballaca: 1500mm ilaa 4050mm,
Dhererka: 3000mm ilaa 15000mm
