Exporter Tuam Tshoj Steel Welded Carbon yeeb nkab
ExportCarbon Steel Yeeb Nkab,Tuam Tshoj Steel Yeeb Nkab,Tsawg carbon steel yeeb nkab,welded kav, los ntawm Tuam Tshoj. Peb lub tuam txhab tshwj xeeb hauv kev xa tawm cov welded steel kav thiab seamless steel kav. Ntau txhiab tons ntawm welded steel kav raug xa tawm txhua xyoo. Welded kav uas feem ntau xa tawm tau muab faib ua LSAW thiab SSAW. Koj puas paub qhov txawv ntawm LSAW Pipe thiab SSAW Pipe?
LSAW Pipe (Longitudinal Submerged Arc-Vuam Yeeb), kuj hu ua SAWL yeeb nkab. Nws yog noj cov phaj steel li raw khoom, pwm nws los ntawm lub tshuab molding, ces ua ob-sided submerged arc vuam. Los ntawm cov txheej txheem no, LSAW steel yeeb nkab yuav tau txais zoo heev ductility, weld toughness, uniformity, plasticity thiab zoo sealing.
LSAW yeeb nkab txoj kab uas hla yog loj dua ERW, feem ntau ntawm 16 nti mus rau 60 nti, 406mm txog 1500mm. Kev ua tau zoo ntawm kev kub siab ua haujlwm, thiab qis-kub corrosion kuj.
Nws tau dav siv nyob rau hauv cov roj thiab roj pipelines, tshwj xeeb tshaj yog yuav tsum tau loj txoj kab uas hla thiab tuab phab ntsa yeeb nkab nrog lub siab zog thiab ntev nyob deb. Meanwhile nyob rau hauv kev tsim kho ntawm cov qauv uas xav tau lub zog tawv, kev kho dej, thermal kev lag luam, choj tsev, thiab lwm yam raws li API specifications, LSAW yeeb nkab (SAWL yeeb nkab los yog JCOE yeeb nkab) yog tshwj xeeb uas tsim nyob rau hauv loj scaled roj thiab roj tsheb thauj mus los, nyob rau hauv cov ntaub ntawv uas. pipelines thoob plaws hauv nroog, hiav txwv, thiab hauv nroog. Cov no yog chav kawm 1 thiab chav kawm 2.
SSAW Pipe (Spiral Submerged Arc-Welding Pipe), kuj hu ua HSAW yeeb nkab (Helical SAW), vuam kab zoo li lub helix. Nws yog siv tib lub vuam tshuab ntawm Submerged Arc-Vuam nrog LSAW yeeb nkab. Sib txawv SSAW yeeb nkab yog kauv welded qhov twg LSAW yog longitudinally welded. Kev tsim cov txheej txheem yog dov cov hlau sawb, ua kom cov kev taw qhia dov muaj lub kaum sab xis nrog cov kev taw qhia ntawm cov yeeb nkab chaw, sib sau thiab vuam, yog li cov vuam seam yog nyob rau hauv ib tug kauv kab.
SSAW yeeb nkab txoj kab uas hla yog los ntawm 20 nti mus rau 100 nti, 406 hli mus rau 2540 mm.Qhov kom zoo dua yog peb tuaj yeem tau txais cov kab sib txawv ntawm SSAW kav nrog tib qhov loj ntawm cov hlau sawb, muaj daim ntawv thov dav rau cov khoom siv raw. steel sawb, thiab vuam seam yuav tsum zam qhov kev nyuaj siab, kev ua yeeb yam zoo los tiv thaiv kev ntxhov siab.
Qhov tsis zoo yog qhov tsis zoo ntawm lub cev, vuam seam ntev ntev dua li cov yeeb nkab ntev, yooj yim ua rau qhov tsis xws luag ntawm cov kab nrib pleb, lub qhov cua, cinder inclusion, ib nrab vuam, vuam quab yuam nyob rau hauv txoj cai rub.
Rau cov roj thiab cov kav dej, tab sis nyob rau hauv cov qauv tsim roj av, SSAW yeeb nkab / HSAW yeeb nkab tsuas yog siv tau rau hauv chav kawm 3 thiab chav kawm 4. Kev tsim qauv, kev thauj dej thiab dej phwj tuaj kho, kev lag luam thermal, vaj tsev thiab lwm yam.
Txheej txheem cej luam
Daim ntawv thov
Nws yog siv rau kev quab yuam thiab qhov siab, thiab rau lub hom phiaj dav dav, dej, roj thiab cov kav dej.
