Kev piav qhia
ERW steel yeeb nkab yog ncaj weld yeeb nkab, hluav taws xob tsis kam vuam, cov ntawv luv rau ERW rau kev thauj cov roj thiab cov pa roj nkev vapor kua khoom, tuaj yeem ua tau raws li qhov xav tau ntawm kev kub siab thiab tsis tshua muaj siab, kev thauj mus los hauv ntiaj teb nrog cov yeeb nkab sector suav nrog txoj haujlwm tseem ceeb.
ERW raj yog "siab zaus kuj welded steel yeeb nkab", thiab cov txheej txheem welded yeeb nkab vuam tsis zoo ib yam, vuam seam yog tsim los ntawm lub cev steel ntawm lub hauv paus hlau, lub zog txhua yam zoo dua li cov yeeb nkab dav dav.

ERW yeeb nkab yog vim siv cov kub- dov coil raws li cov khoom siv raw, cov phab ntsa tuab tuab tuaj yeem tswj tau ntawm li +- 0.2mm, ob qhov kawg ntawm cov yeeb nkab steel raws li APL tus qauv thiab GB / t9711.1 tus qauv, kawg trimming ntaus zawj, ruaj ntev xa thiab lwm yam zoo. Nyob rau hauv xyoo tas los no, natural gas pipeline network engineering thiab gas tuam txhab uas muag tau dav siv ERW yeeb nkab ua lub ntsiab yeeb nkab network ntawm lub nroog.
Daim ntawv thov
Cov yeeb nkab yog siv rau kev thauj mus los thiab Kev Tsim Kho feem ntau siv hauv kev lag luam xws li Coal gas, Chav, Dej, Petroleum, Natural gas.
