Hoobkas pheej yig Tuam Tshoj High Quality Ncaj Carbon Steel Welded Pipes
Txheej txheem cej luam
"Tswj tus qauv los ntawm cov ntsiab lus, qhia lub zog los ntawm qhov zoo". Peb lub tuam txhab tau siv zog los tsim kom muaj txiaj ntsig zoo thiab ruaj khov cov neeg ua haujlwm cov neeg ua haujlwm thiab tshawb nrhiav cov txheej txheem tswj kev ua haujlwm zoo rau Ncaj Carbon Steel Welded Pipes. Zoo zoo yog lub Hoobkas muaj nyob, tsom rau cov neeg siv khoom xav tau yog lub hauv paus ntawm lub tuam txhab kev muaj sia nyob thiab kev nce qib, Peb ua raws li kev ncaj ncees thiab kev ntseeg zoo tshaj tus cwj pwm ua haujlwm, yos hav zoov rau pem hauv ntej ntawm koj tuaj!
Rau welded carbon steel yeeb nkab, muaj 2 lub ntsiab technology yuav tsum tau nco ntsoov tias yog ERW (hluav taws xob kuj weld) thiab SAW (submerge arc weld). Cov kav dej siv cov thev naus laus zis no ob qho tib si tsuas yog siv rau kev lag luam roj av rau kev thauj roj thiab roj, tab sis lawv txhua tus muaj lawv tus kheej kom zoo dua, yog li kev siv sib txawv.
ERW yeeb nkab yog tsim los ntawm steel phaj, tsuas muaj ib tug welded seam, thiab vim hais tias welded kab ntawm ERW yeeb nkab yog los ntawm leej niam yeeb nkab, tsis xav tau solder flux, yog li txhua yam khoom yog zoo nkauj heev. Thiab vim nws cov yam ntxwv ntawm kev ua haujlwm siab, tus nqi qis, cov khoom siv txuag, thiab kev ua haujlwm yooj yim, piv nrog SAW yeeb nkab, ERW yeeb nkab yog cov yeeb nkab steel nrog cov khoom ua tau zoo, ua tau zoo thiab kev lag luam zoo hauv kev lag luam roj thiab roj. thiab kev thauj mus los. Tshwj xeeb tshaj yog ua raws li kev loj hlob ntawm cov cuab yeej technology, zoo yog welded kab yog ntau thiab zoo dua, los ntawm kev siv cov cuab yeej tshiab tshaj plaws, lub hom phiaj yog tshem tawm kev ntxhov siab, soften thiab refine tus qauv, thiab txhim kho cov khoom siv txhua yam ntawm vuam kub cuam tshuam cheeb tsam. Hom ERW yeeb nkab no tsis yog tsuas yog qhov vuam tsis tuaj yeem sib txawv, tab sis kuj tseem muaj qhov sib txawv ntawm qhov sib txawv ntawm 1, uas paub txog qhov sib txuam ntawm qhov chaw vuam nrog cov khoom siv hauv paus.
Pom cov thev naus laus zis tam sim no muaj ntau heev, thiab cov flux txheej tiv thaiv sai sai ua kom nrawm kub thiab ua rau nws muaj qhov chaw soldering. Submerged arc welding muaj qhov zoo ntawm weld seam zoo, kev ua haujlwm siab, tsis muaj arc teeb thiab cov pa luam yeeb me me. Submerged arc welded steel kav yog dav siv hauv cov hlab ntsha siab, cov yeeb nkab fittings, kab teeb, kab, cov kua dej tsis tshua muaj siab, thiab cov phiaj xwm steel. Tab sis nyob rau hauv tsim lub teb chaws kev lag luam roj av, SAW yeeb nkab tsis raug tso cai nyob rau hauv vim nws tus kheej txwv, tsuas yog nyob rau hauv Tuam Tshoj SAW yeeb nkab tseem raug tso cai nyob rau hauv roj av kev lag luam nrog txwv.
Zoo zoo thiab tus nqi tsim nyog "yog peb cov qauv kev lag luam. Yog tias koj txaus siab rau peb cov khoom thiab cov kev daws teeb meem lossis muaj lus nug, nco ntsoov tiv tauj peb. Peb vam tias yuav tsim kev sib raug zoo nrog koj nyob rau yav tom ntej.
Daim ntawv thov
Nws yog siv rau kev quab yuam thiab qhov siab, thiab rau lub hom phiaj dav dav, dej, roj thiab cov kav dej.
