ERW steel yeeb nkab

ERW steel yeeb nkab yog ib tug ncaj seam hluav taws xob kuj welded yeeb nkab, abbreviated li ERW yeeb nkab, uas yog ib puag ncig yeeb nkab welded los ntawm steel daim hlau. Nws yog siv los thauj cov vapor thiab kua khoom xws li roj thiab n atural gas, thiab tuaj yeem ua tau raws li ntau yam kev xav tau ntawm kev kub siab thiab qis.
