Ibikorwa byo gukoraASTM A252 Umuyoboro wa LSAW:

Longitudinal Submerged-arc Welded (LSAW) Umuyoboro ukoresha tekinoroji yo gusudira arc yo mumazi, ukoresheje gusudira kuzuza, gukingira ibice flux yashyinguwe arc.

LSAW ni impfunyapfunyo y'Icyongereza ya arc yarengewe na welded igororotse icyuma.Igikorwa cyo kubyaza umusaruro arc yacometse arc umuyoboro wicyuma ugizwe nicyuma gikora tekinoroji ya JCOE, coil ikora tekinoroji yo gusudira arc hamwe na tekinoroji ya UOE.

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

Ikizamini cya mashini

Ikizamini cyo Kunama -uburebure buhagije bwumuyoboro bugomba guhagarara bukonje kugeza kuri 90 ° hafi ya manda ya silindrike.

Ikizamini cya Flattening-nubwo ibizamini bidasabwa, umuyoboro ugomba kuba wujuje ibyangombwa bisabwa.

Ikizamini cya Hydro-static -usibye ko byemewe, buri burebure bwumuyoboro bugomba gukorerwa hydro-static nta kumeneka kurukuta rwumuyoboro.

Ikizamini cy'amashanyarazi kidahwitse-nk'ikindi kizamini cya hydro-static, umubiri wuzuye wa buri muyoboro ugomba kugeragezwa hamwe nikizamini cyamashanyarazi kidafite ingufu.ahakorerwa ikizamini cyamashanyarazi kidakorwa, uburebure bugomba gushyirwaho inyuguti "NDE"

Ubworoherane bwa diameter yo hanze, uburebure bwurukuta, uburebure n'uburemere:

Hanze ya Diameter	Diameter yo hanze yibirundo by'imiyoboro ntishobora gutandukana kurenza ± 1% uhereye kumurambararo wagaragaye.
Ubunini bw'urukuta	Umubyimba wurukuta umwanya uwariwo wose ntushobora kurenza 12.5% munsi yubugari bwurukuta.
Uburebure	Ibirundo by'imiyoboro bigomba gutangwa muburebure bumwe, uburebure bubiri, cyangwa muburebure bumwe nkuko bigaragara muburyo bwo kugura, ukurikije imipaka ikurikira:	Uburebure bumwe	16 kugeza 25ft (4.88 kugeza 7,62mm), santimetero
