ASTM A302 GR.C Mn-Mo-Ni Alloy Umuvuduko wa Vessel icyuma

ASTM A302 Icyiciro C ni Manganese-molybdenum-nikel alloy boiler ibyuma. Icyuma cya A302 Icyiciro C kizicwa kandi kigomba kuba cyujuje ingano yubunini. Isahani yicyuma A203 Icyiciro C igomba gukorerwa ibizamini kugirango hamenyekane imbaraga zingana, imbaraga zitanga umusaruro, no kuramba. Iyo uzunguza SA302 Icyiciro C munsi yicyuma NACE MR0175, ikizamini cya HIC, SCC, SSC ikorerwa muri laboratoire yacu ya gurantee SA302 Icyiciro cya C. Ibindi bizamini bya tekinoroji, nka PWHT, DWTT, Ikizamini cyo hejuru yubushyuhe bwo hejuru kizatorwa nabakoresha amaherezo niba babisabye.
Umubyimba: 6MM kugeza 300MM,
Ubugari: 1500mm kugeza 4050mm,
Uburebure: 3000mm kugeza 15000mm
