Cov txheej txheem cuam tshuam nrog kev siv cov coils kub ntawm cov hlau kom tsim mus rau hauv ib lub cylindrical puab thiab tom qab ntawd welded raws kauv seam. Qhov tshwm sim yog cov yeeb nkab nrog lub zog siab thiab kav ntev, ua rau nws haum rau ntau cov ntawv thov. Cov kav dej no sivWelded TubeTshuab thaum kev tsim kho, ua kom lawv tiv taus ntau qhov chaw ib puag ncig thiab kev ntsuas, ua rau lawv zoo tagnrho rau kev siv hauv av thiab hauv qab.

    Thaum xav txog cov specifications rau kauv yeeb nkab sib, nws yog ib qho tseem ceeb kom tsom rau cov ntsiab lus tseem ceeb xws li txoj kab uas hla thiab cov qib tuab thiab cov qib. Lub cheeb ntawm cov yeeb nkab txiav txim siab nws lub peev xwm thauj cov kua lossis roj av tuab ua lub luag haujlwm tseem ceeb hauv nws cov qauv kev ntseeg siab thiab siab kuj. Ib qho ntxiv, cov qib kev sawv cev zoo thiab muaj pes tsawg leeg ntawm cov hlau siv thiab yog qhov kev txiav txim siab tseem ceeb hauv kev ua kom muaj kev sib txawv thiab kev ua tau zoo ntawm cov yeeb nkab hauv ib daim ntawv thov.

    Hauv kev tsim kho ntawmNcej Lub Ntsiab Main, kauv nqaws dej pipes muaj ntau yam zoo. Lawv lub zog tensile siab thiab corrosion tsis kam ua rau lawv thauj cov dej dhau mus, thaum lawv saj mus ntev, thaum lawv yooj yim nyob ib puag ncig cov nyom thiab hauv strawain. Tsis tas li ntawd, kev siv kauv seam pipes hauv cov roj cua uas muaj peev xwm thauj khoom muaj kev nyab xeeb thiab cov khoom siv tseem ceeb rau cov chaw nyob, ua lag luam thiab cov haujlwm.

    Muab Kauv Steel Yeeb Nkab

    Ntawm lub hauv cov txheej txheem sab hauv, muab kauv seam cov yeeb nkab cov qauv kev lag luam thiab cov kev tswj hwm kom ntseeg tau tias lawv cov kev ua tau zoo thiab ua tau zoo. Piv txwv li, Asmeskas Asmeskas cov khoom siv roj av (API) tau tsim cov qauv siv hluav taws xob uas yuav tsum muaj rau qhov loj me, lub zog, thiab cov txheej txheem sim. Tsis tas li ntawd, Asmeskas haiv neeg rau kev sim thiab cov khoom siv (cov khoom siv mechanium los muab cov khoom sib xyaw rau cov khoom siv sib luag kom ua kom lawv txoj kev ntseeg tau thiab ua raws li cov qauv kev lag luam.

    Hauv cov ntsiab lus, cov kauv welded yeeb nkab specification yog qhov tseem ceeb rau lawv lub luag haujlwm hauv kev tsim kho vaj tse. Txawm hais tias siv rau cov dej loj lossisRoj Kab, cov kav dej no muab cov khoom tsis muaj zog, kav ntev thiab versatility, ua rau lawv tsis tseem ceeb hauv ntiaj teb niaj hnub. Los ntawm adhering rau cov qauv kev lag luam thiab cov cai, kev siv kauv seam kav dej kom ntseeg tau tias kev txhim kho kev nyab xeeb thiab kev nce qib.
