1. ** Dab tsi yog erw yeeb nkab? **
Ib qho ERW (hluav taws xob tiv thaiv welded) cov yeeb nkab yog ib hom steel sawb (skelp Nws yog qhov kev nrawm nrawm, cov txheej txheem siv nyiaj zoo rau kev tsim cov kav dej ntev hauv ntau qhov ntau thiab tsawg, siv rau kev siv cov khoom kom qis dua thiab cov kev siv cov qauv txheej txheem.
2. ** Dab tsi yog qhov sib txawv ntawm ERW thiab CEW leeg? **
Cov ntsiab lus sib txawv hauv cov txheej txheem vuam thiab cov qauv siv hluav taws xob ntau zaus, uas feem ntau ua rau muaj cov khoom siv hluav taws xob tsawg dua, uas feem ntau ua rau muaj kev sib tw weld hlaws dai thiab muaj peev xwm Ntau dua cov teeb meem kub ntau dua; Niaj hnub nimno "Erd" encompass cov txheej txheem siab tshaj plaws (HFW) uas ua rau cov txheej txheem qub dua.
3. ** Dab tsi yog lsaw yeeb nkab? **
LSAW tawm (Longitudinal submerged arc welded) yeeb nkab tsim los ntawm ob qho tib si sab hauv thiab sab nraud siv cov txheej txheem hauv qab no (pom) Tus txheej txheem no tau zoo rau cov phab ntsa thicker thiab ntau dua li 24 ntiv tes sib kis tau zoo li uoe lossis JCO nias.
4. ** VEW txhais li cas? **
ERW sawv rau ** e ** RECTRAT ** R ** esistance ** w ** elding (lossis ** w ** elded). Nws yog hais txog qhov txheej txheem tsim kev tsim khoom tshwj xeeb uas yog cov leeg ua haujlwm ntev los ntawm cov hlau hluav taws xob yog tsim los ntawm cov hluav taws xob uas yog hluav taws xob tam sim no (feem ntau yog cov zaus los ntawm kev tiv tauj sawv.
5. ** Qhov twg yog qhov zoo dua, seamless lossis ERW YEEB? **
Tsis yog thoob plaws "zoo dua"; Kev xaiv yog nyob ntawm daim ntawv thov yuav tsum tau ua. Seamless cov yeeb nkab, ua los ntawm tho ib lub nplua nuj, muaj cov kev pab muaj zog, thiab cov kev pab cuam siab zoo, thiab cov roj muaj zog, cov roj muaj txiaj ntsig zoo, roj av khov kho thiab roj). ERW cov yeeb nkab feem ntau tau nqi ntau dua, npaj muaj nyob hauv qhov ntau thiab tsawg, thiab tau txhim kho kom zoo dua vim niaj hnub hfw thev naus laus zis; Nws ua tau zoo tshaj plaws hauv ntau cov tshuaj hauv nruab nrab, cov kev npaj ua kom zoo nkauj, thiab cov khoom siv txhua yam uas tsis muaj zog tsis muaj zog. Tus nqi thiab kev kawm tshwj xeeb xav tau dictate xaiv.
