Cov yeeb nkab steel yog cov kav ntev cylindrical ua los ntawm cov hlau siv los thauj cov kua, gases thiab cov khib nyiab nyob rau hauv siab siab lossis kub. Cov kav hlau hlau tau siv dav hauv ntau qhov kev lag luam xws li roj thiab roj, kev kho dej, kev tsim kho thiab kev ua liaj ua teb. Nyob ntawm daim ntawv thov, lawv tuaj nyob rau hauv ntau qhov ntau thiab tsawg, duab thiab thicknesses. Cov kav hlau hlau tuaj yeem tsim los ntawm cov txheej txheem sib txawv xws li welded, seamless lossis lsaw nyob ntawm lub hom phiaj ntawm kev siv. Lawv feem ntau superior rau lwm cov ntaub ntawv vim lawv lub zog, corrosion kuj thiab muaj peev xwm tiv taus huab cua huab cua.
LSAW (Longitudinal Submerged Arc Vuam) welded steel yeeb nkab yog tsim los ntawm kev tsim thiab vuam ntev strips ntawm cov hlau rau hauv cov duab cylindrical siv cov txheej txheem submerged arc vuam. Cov txheej txheem vuam yog siv los ntawm ib qho hluav taws xob arc uas yog immersed nyob rau hauv ib txheej ntawm flux. Lub flux ua raws li cov khoom siv tiv thaiv, tiv thaiv lub arc los ntawm kev sib cuag nrog cua.
Raws li cov txheej txheem molding sib txawv, nws tuaj yeem muab faib ua:
UOE Steel Yeeb Nkab: Tom qab ntug ntawm ib lub phaj steel yog ua ntej khoov, nws nkag mus rau U-puab, O-puab, hauv vuam, sab nraud vuam, txias mechanical expansion thiab lwm yam txheej txheem.
JCOE Steel Yeeb Nkab: Tom qab "JCOE" pre-weld, sib sau, tom qab vuam txias expansion thiab lwm yam txheej txheem
HME steel yeeb nkab: mandrel dov tom qab "CCO", txias expansion tom qab vuam thiab lwm yam txheej txheem.
Nws yog lub raj steel ua los ntawm kev tsim cov phaj hlau thiab vuam rau hauv lub tog raj kheej siv cov txheej txheem submerged arc vuam. Nws yog dav siv hauv kev lag luam roj thiab roj rau kev xa khoom ntawm cov roj av thiab roj av. LSAW tubing paub txog nws lub zog siab, ua haujlwm ntev thiab corrosion tsis kam. Lawv kuj zoo dua rau lwm hom kav dej raws li lawv tuaj yeem tiv taus kev kub ntxhov thiab kub kub.
Cov kav dej LSAW feem ntau yog siv los thauj cov roj, roj thiab dej. Lawv kuj tau siv los tsim cov kev tsim kho vaj tse xws li txuas hniav thiab qhov tunnels. Cov txheej txheem vuam siv los tsim LSAW tubing yog qhov ua tau zoo thiab ua kom muaj zog, ruaj khov, loj txoj kab uas hla.
