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 los hauv lub ntiaj teb.
Thaum vuam ERW cov kav dej, cov cua sov tso tawm thaum tam sim no ntws los ntawm qhov chaw 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 sau cov qauv uas feem ntau hauv cov kav dej.
