ERW steel yeeb nkab yog tsim los ntawm tsawg zaus los yog siab zaus tsis kam "ua haujlwm".Lawv yog cov raj puag ncig welded los ntawm steel phaj nrog longitudinal vuam.
Thaum lub sij hawm ERW tube welding, cua sov yog generated thaum hluav taws xob tam sim no ntws los ntawm qhov chaw ntawm lub welded cheeb tsam.Nws heats ob ntug ntawm cov hlau mus rau qhov chaw uas ib tug ntug yuav ua tau ib daim ntawv cog lus. Tib lub sij hawm, nyob rau hauv lub siab ua ke, cov npoo ntawm lub raj dawb paug yog melted thiab squeezed ua ke.
Feem ntau ERW yeeb nkab muaj qhov siab tshaj plaws OD ntawm 24 "(609mm), rau qhov loj dua cov yeeb nkab yuav raug tsim hauv SAW.
Muaj ntau cov kav dej uas tuaj yeem ua tau los ntawm cov txheej txheem ERW.Nyob hauv qab no peb sau cov qauv siv ntau tshaj plaws hauv cov kav dej.

Daim ntawv thov thiab kev siv ERW steel yeeb nkab: ERW steel yeeb nkab yog siv los thauj cov pa roj thiab cov khoom ua kua xws li roj thiab roj, thiab tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm qhov tsis tshua muaj siab thiab siab siab.Nyob rau xyoo tas los no, nrog rau kev txhim kho ERW thev naus laus zis, ntau thiab ntau ERW steel kav yog siv hauv cov roj thiab roj, kev lag luam tsheb thiab lwm yam kev lag luam.
