Muaj ob peb yam ntawm kev sib txawv ntawm ERW steel kav thiab seamless kav hlau. ERW cov kav dej yog siv rau hauv kev thauj mus los ntawm cov kua, xws li roj, roj thiab lwm yam, tsis hais nws lub siab, uas ua rau nws yog ib qho ntawm cov raj xa khoom thoob plaws thoob ntiaj teb. Seamless cov kav dej yog, ntawm qhov tod tes, yog ib hom kev xa cov yeeb nkab steel zoo li cov duab plaub fab lossis duab plaub tsis muaj qhov sib txuas nrog cov hollow khaub lig-ntu, uas yog siv rau hauv cov kua xa tawm nrog rau ua cov qauv thiab tshuab, ua tsaug rau nws qhov siab anti-bending thiab anti-torque lub zog thiab tsis ntseeg qhov pom kev. Feem ntau, ERW thiab cov kav hlau tsis xeb hlau tau sib txawv me ntsis hauv kev siv.
Qhov loj tshaj plaws ntawm ERW cov yeeb nkab thiab cov kav hlau tsis xeb hlau loj yog tias ERW cov yeeb nkab muaj vuam kab, uas yog tib yam li welded steel yeeb nkab, tab sis cov yeeb yaj kiab dub hlau tsis muaj, tsis hais lub welded steel yeeb nkab. Tsis tas li ntawd, vuam kab ntawm ERW yeeb nkab yog tus yuam sij rau qhov zoo ntawm ERW steel yeeb nkab. Tshaj qhov tsis tau pom dua ntawm cov vuam kab ntawm ERW yeeb nkab yog, kev ua haujlwm siab dua ERW yeeb nkab muaj.
Muaj ob txoj hauv kev los tshem tawm cov vuam kab: geometric seamlessly thiab lub cev seamlessly. Geometric seamlessly yog tshem tawm cov burr ob sab hauv thiab sab nraud thaum lub cev sib dhos yog ua cov kauj ruam los ua cov hlau thiab cov qauv xim hlau tsis xwm yeem thiab zoo ib yam, uas zoo li nyuaj rau kom ua tiav, txawm li cas los xij, ERW cov yeeb nkab tsis muaj vuam kab tuaj yeem ua tiav tau zoo uas.
Piv nrog rau cov txheej txheem ua ntawm ERW cov yeeb nkab, cov txheej txheem kev ua tiav ntawm cov hlau yeeb nkab tsis huv yog ntau yooj yim dua. Muaj ob yam sib txawv ntawm cov txheej txheem txheej txheem: kos duab txias thiab dov kub. Piv nrog kub dov, txheej txheem thev naus laus zis ntawm kev kos duab txias yog qhov nyuaj ntxiv. Ntxiv mus, nyob rau hauv cov tsos, txias-kos seamless stainless-steel yeeb nkab yog luv dua kub-dov ib qho thiab cov phab ntsa tuab ntawm txias-kos seamless stainless-steel yeeb nkab feem ntau me dua li cov phab ntsa tuab ntawm kub-dov ib. Dab tsi ntxiv, cov txheej txheem thev naus laus zis ntawm cov kub dov xav tau qhov kub siab uas yuav txo tau qhov ua haujlwm ntawm deformation kom thiaj li ua tiav qhov cuam tshuam loj. Feem ntau hais lus, cov txheej txheem thev naus laus zis ntawm ERW cov yeeb nkab thiab cov kav hlau tsis xeb hlau tau sib txawv heev, vim muaj cov tsos sib txawv.
Feem ntau, txawm hais tias ERW cov yeeb nkab thiab cov kav hlau tsis xeb hlau ob leeg tau ua lub luag haujlwm tseem ceeb raws li qhov txuas ntawm cov yeeb nkab welded ua tsis tau zoo hauv kev tsim kho hauv zej zog, ERW cov yeeb nkab thiab cov yeeb nkab tsis sib haum muaj kev siv sib txawv thiab sib txawv ua tiav ua tsaug rau lawv cov tsos sib txawv
Txheeb xyuas seb cov yeeb nkab yog ERW lossis seamless, tsuas yog nyeem stencil ntawm sab yeeb nkab. Yog tias nws yog ASTM A53, Hom S txhais tau tias seamless; Hom F yog cua sov tab sis welded; Hom E yog Hluav Taws Xob tiv thaiv welded. Nws yog qhov yooj yim tshaj plaws los txheeb xyuas seb puas muaj cov yeeb nkab txuas yog ERW lossis seamless.
Hauv cov ntawv luv luv, cov kav dej tsis sib haum yog kev lag luam ntawm qhov kev tawm tsam uas tsis muaj hnub nyoog hais tias nws tsis muaj qhov tsis zoo tab sis qhov txuas ntawd muaj qhov tsis txaus ntseeg thoob plaws qhov ntev ntawm txhua lub raj, raws li tau hais los saum no. Intuitively cov tswvyim no yooj yim txais los ntawm kev yuav khoom thiab kev tsim qauv nrog kev paub tsawg nrog ntau yam khoom lag luam. Txhua cov qauv khoom thiab kev tsim qauv muaj nws tus kheej qhov teeb meem thiab qhov ua tsis tiav.
Cov neeg tau txais kev pab yuav tsum paub zoo txog cov teeb meem thiab qhov tsis xws luag, thiab lawv yuav cuam tshuam li cas rau cov kev thov tshwj xeeb. Tom qab ntawv lawv tuaj yeem txiav txim siab raws qhov tseeb, tsis yog dab neeg.
