ERW steel kavyog tsim los nrog tsawg zaus lossis siab zaus hluav taws xob tsis kam "ua haujlwm".Lawv yog cov kav dej puag ncig welded los ntawm cov nplooj ntawv steel nrog longitudinal seams.Nws yog siv los thauj cov roj thiab cov khoom ua kua xws li roj thiab cov nkev, thiab tuaj yeem ua tau raws li ntau yam kev xav tau ntawm kev kub siab thiab qis.Tam sim no nws nyob hauv txoj haujlwm tseem ceeb hauv kev thauj mus loscov kav dejhauv ntiaj teb no.
Thaum twgvuam ERW kav, Thaum tshav kub kub tso tawm thaum tam sim no ntws los ntawm kev sib cuag ntawm thaj chaw vuam.Nws heats ob lub npoo ntawm cov hlau mus rau qhov chaw uas ib tug ntug tuaj yeem tsim ib daim ntawv cog lus.Nyob rau hauv rooj plaub no, nyob rau hauv kev sib koom siab, cov npoo ntawm cov yeeb nkab yog melted thiab extruded ua ke.Feem ntauERW cevmuaj qhov siab tshaj plaws sab nraud ntawm 24 ntiv tes (609 mm), cov kav dej loj yog tsim los ntawm SAW.
Muaj ntau cov kav dej uas tuaj yeem ua tau siv txoj kev ERW.Hauv qab no peb teev cov qauv siv ntau tshaj hauv cov kav dej.ERW ASTM A53 Qib A thiab B carbon steel kav (thiab galvanized) ASTM A252carbon steel kavASTM A500 pawg kav ASTM A134 thiab ASTM A135 cov kav dej EN 10219 cov kav dej S275, S355 cov kav dej.ERW Stainless Hlau Yeeb Nkab ASTM A269 Cov Qauv & Specifications ASTM A270 Stainless Hlau Yeeb Nkab ASTM A312 Stainless Steel Pipe Cov yeeb nkab steel .API ERW kab yeeb nkab API 5L B rau X70 PSL1 (PSL2 yuav tsum yog HFW txheej txheem) API 5CT J55/K55, N80 casing thiab tubing.
Daim ntawv thov thiab siv ERW steel yeeb nkab: ERW steel yeeb nkab yog siv los thauj cov roj thiab cov khoom ua kua xws li roj thiab cov nkev, thiab tuaj yeem ua tau raws li qhov yuav tsum tau ua kom qis thiab siab.Nyob rau hauv xyoo tas los no, nrog rau txoj kev loj hlob ntawm ERW technology, ntau thiab ntau ERW steel kav yog siv nyob rau hauv roj thiab roj teb, automotive kev lag luam, thiab lwm yam.
