{{0 {{}}}} Dab tsi yog qhov sib txawv ntawm ERW thiab seamless steel yeeb nkab? **
* ** NTXIV: ** Cov ntsiab lus tseem ceeb yog nyob rau hauv ** kev tsim khoom lag luam ** thiab lub txiaj ntsig * yeeb nkab qauv **:
* ** ERW (hluav taws xob tiv thaiv welded) yeeb nkab: **
* ** Tus txheej txheem: ** Tsim los ntawm dov ib lub tiaj tus kab txaij (skelp) rau hauv cov npoo hluav taws xob zoo li no los ntawm cov hluav taws xob high-zaus, thiab forging lawv ua ke hauv siab .
* ** SEAM: ** Muaj qhov sib txawv welded seam raws nws qhov ntev . Cov txheej txheem niaj hnub hfi-erw tsim cov khoom lag luam zoo heev.
* ** Kev sib txuam: ** Phab ntsa tuab yog feem ntau yog ib puag ncig ntawm txoj kev.
* ** Tus nqi: ** Feem ntau tsis tshua kim dua seamless yeeb nkab .
* ** Qhov loj me: ** Feem ntau tsim tawm hauv ntau thiab tsawg los ntawm 1/8 "rau 24" NPS thiab loj dua.
* ** Cov ntawv thov: ** Cov kav dej, cov txheej txheem qis / nruab nrab txheej txheem, fencing, rooj tog zaum, tsheb .
* ** SEAMLESS YEEB: **
* ** Ua cov txheej txheem: ** Ua los ntawm tho ib lub zog cylindrical billet ntawm rhuab plhaub (mandrel zeb), lossis los ntawm exprel zeb), lossis los ntawm exprel zeb), lossis los ntawm exchlel zeb), lossis los ntawm expet plhaub)
* ** SEAM: ** TSIS MUAJ WELDED SEAM tshwm sim; cov yeeb nkab txuas ntxiv thoob plaws nws txoj kev.
* ** Kev sib txuam: ** Phab ntsa tuab yuav txawv me ntsis nyob ib puag ncig ntawm txoj kab piv rau erw .
* ** Tus nqi: ** Feem ntau kim dua li ERW cov yeeb nkab vim muaj cov txheej txheem ntau ntxiv .
* ** Qhov loj me: ** Feem ntau tsim los ntawm 1/8 "rau 24" NPS, txawm hais tias muaj ntau tshaj li erw .
* ** COV KEV PAB CUAM: ** KEV PAB CUAM ZOO HEEV (Cov Khoom Siv Hluav Taws Xob
