Ubu dufite itsinda ryabahanga, rikora kugirango ritange serivisi nziza kubakiriya bacu.Dukunze gukurikiza amahame agenga abakiriya, ibisobanuro-byibanze kuriUbushinwa LSAW / SSAW Umuyoboro w'icyuma n'umuyoboro wo gusudira, Inshingano yacu ni ugutanga agaciro keza kubakiriya bacu ndetse nabakiriya babo.Uku kwiyemeza gucengera mubyo dukora byose, bikadutera guhora dutezimbere no kunoza ibisubizo byacu hamwe nuburyo bwo kuzuza ibyo ukeneye.
Umuyoboro watumijwe muri iki cyerekezo ukoreshwa muri serivisi y’umuvuduko mwinshi ku kirere no mu bushyuhe bwo hasi.Bikoreshwa cyane mu kohereza peteroli na gaze gasanzwe.
ASTM A671 LSAW (JCOE) Umuyoboro wa Carbone ugomba gusudwa 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: LSAW (JCOE) Imiyoboro yicyuma
Ingano: OD: 406 ~ 1500mm WT: 6 ~ 40mm
Icyiciro: CB60, CB65, CC60, CC65, nibindi.
Uburebure: 12M cyangwa uburebure bwagenwe nkuko bisabwa.
