ERW steel yeeb nkab yog ib hom kev tiv thaiv vuam steel yeeb nkab, siab zaus vuam vuam (Electric Resistance Vuam, luv luv rau ERW) ERW yog thawj tsab ntawv ntawm cov lus Askiv sib xws. Resistance vuam steel yeeb nkab yog muab faib ua ob hom AC vuam steel yeeb nkab thiab DC vuam steel yeeb nkab.
AC vuam yog muab faib ua tsawg zaus vuam, nruab nrab zaus vuam, ultra nruab nrab zaus vuam thiab high-frequency vuam raws li qhov zaus. High zaus vuam yog tsuas yog siv rau nyias-walled steel yeeb nkab.
Tseem yog qhov tsim ntawm cov phab ntsa tuab tuab, kev siv vuam ntau zaus muab faib ua kev sib cuag vuam thiab induction vuam.
Cov yeeb nkab me me feem ntau yog siv rau DC vuam.
Yog li ntawd, feem ntau hais lus, high-frequency welded kav muaj nyob rau hauv ERW kav, uas yog tsim los ntawm high-frequency welding txheej txheem.ERW ncaj seam welded yeeb nkab (ERW) yog lub siab tshaj plaws thiab pheej yig steel yeeb nkab nyob rau hauv lub teb ntawm cov roj thiab roj cia. thiab kev thauj mus los.
