ASTM A672 B60 / B70 / C60 / C65 / C70 LSAW (JCOE) Umuyoboro wa Carbone niikoreshwa mubihe byumuvuduko mwinshi kandi ikoreshwa cyane cyane mumashanyarazi, inganda za peteroli zo hanze, inganda zimiti, Ifumbire, peteroli, inganda nibindi.
ASTM A672 B60 / B70 / C60 / C65 / C70LSAW (JCOE) Umuyoboro wa Carboneigomba gusudira kabiri, gusudira kwuzuye kwakozwe hakurikijwe inzira hamwe nabasudira cyangwa abasudira babishoboye babishoboye bakurikije ASME Boiler hamwe nigitutu cya Vessel Code, Igice cya IX.
Ibyiciro byose bitari 10, 11, 12 na 13 bigomba gukorerwa ubushyuhe mu ziko rigenzurwa kugeza kuri ± 15 ℃ kandi bigashyirwaho hydrometero yafashwe kugirango inyandiko zishyushya ziboneke.
Inganda:Kuzenguruka Arc Welding (LSAW).
Ingano:OD: 406 ～ 1422mm WT: 8 ～ 60mm.
Icyiciro:B60, C60, C65, nibindi
Uburebure:3-12M cyangwa uburebure bwagenwe nkuko bisabwa.
