(1) welded yeeb nkab los ntawm steel phaj welding rau hauv cov yeeb nkab puag ncig, muab faib ua ntau zaus kuj welded yeeb nkab (ERW welded yeeb nkab), ncaj seam arc vuam yeeb nkab (LSAW), kauv welded yeeb nkab.Electrical engineering nrog "SC", tuaj yeem siv. raws li cov kav dej roj kuj tseem siv tau los ua cov yeeb nkab threading, kuj tuab.

(2) Cov yeeb nkab yeeb nkab, tseem hu ua cov yeeb nkab xaim, yog nyias nyias, txhais los ntawm "T", thiab tsuas yog siv tau rau threading.ERW steel pipeERW steel yeeb nkab.

(3) ERW raj yog "siab zaus tsis kam vuam steel raj", thiab cov txheej txheem vuam sib txawv yog qhov sib txawv, cov kab vuam yog los ntawm cov khoom siv hauv cov hlau siv lub cev melted, lub zog txhua yam zoo dua li cov vuam dav dav.ERW sawv. rau welding tsis kam, tsis kam vuam muaj cov yam ntxwv ntawm kev ua haujlwm siab, tsis tshua muaj nqi, cov khoom txuag thiab yooj yim automation, yog li nws yog dav siv nyob rau hauv aviation, aerospace, zog, electronics, automotive, lub teeb kev lag luam thiab lwm yam sectors, yog ib tug ntawm cov cov txheej txheem vuam tseem ceeb.
