ERW Pipe Manufacturing Txheej txheem:

 

Siab- zaus ncaj seam hluav taws xob-kuj welded steel yeeb nkab (erw cev) yog kub-rolled coil tom qab tsim tshuab, kev siv siab - zaus tam sim no ntawm daim tawv nqaij thiab cov teebmeem sib thooj, lub raj ntug cua sov thiab melting, nyem cov menyuam nyob rau hauv siab vuam kom ua tiav ntau lawm.

Siab - zaus kuj welding steel yeeb nkab, vuam yeeb nkab thiab cov txheej txheem vuam zoo tib yam tsis zoo ib yam, qhov vuam yog ua los ntawm cov hlau hlau yaj los ntawm lub cev, lub zog txhua yam zoo dua li cov yeeb nkab dav. Smooth tsos, siab precision, tsis tshua muaj nqi weld siab thiab me me, haum 3PE anti-corrosion txheej. Muaj qhov sib txawv tseem ceeb hauv txoj kev vuam ntawm cov kav dej ntau zaus welded thiab submerged arc welded yeeb nkab. Raws li cov vuam ua tiav tam sim ntawm kev kub ceev, qhov nyuaj ntawm kev ua kom zoo ntawm vuam yog ntau dua li ntawm submerged arc vuam.
