Uburyo bwo gukora umuyoboro wa Longitudinal Submerged-arc Welded Pipe:

Umuyoboro wa LSAWikoresha ikoranabuhanga ryo gusudira arc iri munsi y’amazi, ikoresheje gusudira filler, kurinda uduce duto tw’arc turi mu mazi.

LSAW ni incamake y'icyongereza ivuga ku muyoboro w'icyuma uhuza imiyoboro. Uburyo bwo gukora umuyoboro w'icyuma uhuza imiyoboro uhuza imiyoboro uhuza imiyoboro uhuza imiyoboro uhuza imiyoboro uhuza imiyoboro uhuza imiyoboro uhuza imiyoboro uhuza imiyoboro uhuza imiyoboro uhuza imiyoboro uhuza imiyoboro uhuza imiyoboro uhuza imiyoboro uhuza imiyoboro uhuza imiyoboro uhuza imiyoboro uhuza imiyoboro n'ikoranabuhanga ryo guhuza imiyoboro uhuza ...

Uburyo bwo gukora umuyoboro wa Longitudinal Submerged-arc Welded (LSAW) Pipe ni ubu bukurikira:

Gupima icyuma gipima icyuma gipima → gusya impande → gucuranura mbere → gushushanya → Gusudira mbere → Gusudira imbere → Gusudira hanze → Gusuzuma icyuma gipima → Gusuzuma X-ray → Kwagura → ikizamini cya hydraulic → l. Gusukura → Gusuzuma icyuma gipima → Gusuzuma X-ray → Gusuzuma X-ray → Gusuzuma uduce twa magnetic ku mpera y'umuyoboro

Kwihanganira umurambararo wo hanze, ubugari bw'urukuta, uburebure n'uburemere:

Ingano yo hanze	Umurambararo w'inyuma w'imiyoboro y'amazi ntugomba gutandukana kurenza ± 1% ugereranije n'umurambararo w'inyuma wagenwe.
Ubunini bw'urukuta	Ubugari bw'urukuta aho ari ho hose ntibugomba kurenza 12.5% munsi y'ubugari bw'urukuta bwagenwe.
Uburebure	Imiyoboro y'amazi igomba gushyirwa mu burebure bumwe butunguranye, uburebure bubiri butunguranye, cyangwa mu burebure bumwe nk'uko byavuzwe mu itegeko ryo kugura, hakurikijwe imbibi zikurikira:	Uburebure bumwe butunguranye	Santimetero 16 kugeza kuri 25 (4.88 kugeza kuri mm 7.62), santimetero
		Uburebure bubiri butunguranye	Hejuru ya metero 7.62 (7.62m) hamwe n'impuzandengo ya metero 10.67 (35ft)
		Uburebure bungana	uburebure nk'uko byagaragajwe hamwe n'impinduka zemewe za ± 1 in.
Uburemere	Uburebure bwa buri kirundo cy'imiyoboro bugomba gupimwa ukwabwo kandi uburemere bwacyo ntibugomba gutandukana kurenza 15% hejuru cyangwa 5% munsi y'uburemere bwacyo, bubarwa hakoreshejwe uburebure bwacyo n'uburemere bwacyo kuri buri gice cy'uburebure.
