Inzira yo gukora Longitudinal Submerged-arc Umuyoboro (LSAW) Umuyoboro niyi ikurikira:
Isahani ya Ultrasonic → gusya inkombe → mbere yo kunama → gukora → Mbere yo gusudira eld gusudira imbere → Gusudira hanze → Kugenzura Ultrasonic inspection Kugenzura X-ray → Kwagura test ikizamini cya hydraulic → l.Chamfering inspection Kugenzura Ultrasonic inspection Kugenzura X-ray inspection kugenzura ibice bya magnetiki kugenzura impera
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.
Iherezo: Impera yikibaya, Impera ya Beveled, Yimuwe;
