ERW (hluav taws xob tiv thaiv welded) steel kav yog cov feem ntau siv steel cov khoom lag luam thiab feem ntau yuav tsum tau khoov cov ntawv thov tiag tiag kom tau raws li ntau yam txheej txheem txheej txheem. Kev sib kho tshuab yog siv los ua kom ncaj kav rau hauv cov ntaub ntawv nkhaus raws li qhov xav tau. Yuav luag txhua hom khoom siv hlau thiab kav dej {2} Nrog txhuas, tooj liab, tooj liab, kauv kav, txuas cov kav dej, thiabERW kav- yuav tuaj yeem siv cov txuj ci tsim nyog.
Thaum nws los txog rau erw steel yeeb nkab dabtsi yog khoov, cov khoom siv tsis yog tshwj xeeb yog siv. Ua raws li cov yeeb nkab taub, phab ntsa tuab, thiab yuav tsum tau khoov vojvoog, cov kev sib txawv xws li kev raug xaiv los yog thawb khoov.
Kev puas txias txias yog tsim nyog rau cov kav dej nrog cov phab ntsa thinner thiab cov kev xav tau siab. Nws tau tuav cov tsos du thiab muaj qhov ntev tom qab khoov.
Kub los yog khoov, ntawm qhov tod tes, yog qhov zoo rau cov loj- txoj kab uas hla thiab tuab {1}- piped kav. Cov yeeb nkab yog rhuab muag kom muag nws ua ntej khoov, txo txoj kev pheej hmoo ntawm kev tawg lossis tawg.
Kuj tseem muaj cov txheej txheem zoo li yob dabtsi yog khoov rau kev kho vajtse uas siv hluav taws xob, Polishing, los yog txhuam hniav, nyob ntawm seb cov phiaj xwm kev xav tau. Qhov no ua rau tsis tsuas yog kev ua tau zoo zoo heev tab sis kuj txhim kho cov hlau, cov hlau sib nraus, thiab tej yam kev sib xyaw ua ke, thiab qee hom plastics, thiab qee yam plastics, ua rau lawv haum rau ntau cov ntawv thov.
Hauv kev teeb tsa pipeline, cov kav xaim khoov yog qhov tseem ceeb txuas cov ntsiab. Lawv feem ntau yog siv los hloov cov kev taw qhia ntawm cov raj xa dej ntawm cov ces kaum ntawm cov ces kaum, ua kom zoo dua qhov txheej txheem tag nrho. Hom Home muaj xws li 90 {{{{}}}℃khoov thiab txoj cai- Lub kaum sab xis khoov. Connection methods vary based on the application environment, including direct welding, hot-melt joining, threaded connections, socket connections, or flange connections.
Txawm hais tias nyob hauv kev lag luam engineering, kev thauj mus los, kev thauj khoom siv hluav taws xob, lossis cov cuab yeej siv hlau, muab cov khoom siv steel uas muaj zog ntxiv rau kev hloov kho kom haum rau cov chaw sib xyaw. Qhov no ua kom cov kev txhim kho txhim kho thiab tag nrho cov system ruaj khov.
Dabtsi yog yog siv tshuab muab cov hlau kav hlau ntau ntxiv thiab muab cov kev daws teeb meem kom muaj txiaj ntsig rau ntau yam ntawm cov engineering tej yaam num.
