    Qhov Zoo ntawm Ob Submerged Arc Welded Gas Yeeb Nkab Featured Duab
    • Qhov Zoo ntawm Ob Chav Submered Arc Welded Roj Kab Yeeb

    Cov lus piav qhia luv luv:

    Zoo siab txais tos rau Cangzhou kauv steel yeeb nkab Group Co., Ltd., cov chaw muag khoom ntawm cov khoom siv zoo welded carbon hlau kav. Peb lub tuam txhab zoo siab siv cov khoom siv hluav taws xob tsim nyog arc vuam tshuab uas tau lees paub ntawm sab saum toj-mape speam kav dej rau ntau cov ntawv thov.


    Khoom Qhia Qhia

    Khoom Ntawv

    Nyob rau hauv lub ntiaj teb ntawm kav dej, muaj ntau yam kev tsim qauv kev tsim kho thiab cov khoom siv. Tus nrov yeeb nkab koom tes yog ob--xaus submerged arc vuam (dsaw). Cov txheej txheem no feem ntau siv rau cov roj av thiab dej hauv dej, thiab rau qhov laj thawj. Hauv cov blog no peb yuav tshawb txog qhov zoo ntawm kev sivOb chav submolled arc weldedyeeb nkab hauv cov ntawv thov no.

    Hydrostatic Kev Ntsuam Xyuas

    Nqe lus piav qhia 3

    Cov yeeb nkab yuav tsum tau txais kev kuaj hydrostatic yam tsis muaj kev lom los ntawm Weld Seam lossis Yeeb Nkab Lub Cev
    Cov tub ntxhais kawm tsis tas yuav muaj kev sim hydrostatically, muab cov feem ntawm cov yeeb nkab siv hauv kev khij cov pob qij txha ua ntej ua ntej kev koom ua haujlwm.

    Helical submerged arc vuam

    Ua ntej, ob chav submerged arc vuam yog ib txoj kev ua tau zoo thiab kev lag luam tau los ntawm kev koom nrog cov kav dej. Cov txheej txheem cuam tshuam nrog kev sib sau weld los ntawm ntsw cov yeeb nkab mus rau hauv glux flux siv ob lub vuam arcs. Qhov no tsim muaj zog thiab ruaj khov weld uas tuaj yeem tiv thaiv siab thiab nruj, ua rau nws zoo rau cov kab roj thiab dej.

    Ib qho ntawm cov ntsiab lus tseem ceeb ntawm ob tog subdgleed arc Welded yeeb nkab yog nws corrosion tsis kam. Cov txheej txheem glux tsim hauv cov txheej txheem Welding tsim cov txheej txheem tiv thaiv dhau ntawm Weld, pab tiv thaiv kom xeb thiab txuas ntxiv lub neej ntawm cov yeeb nkab. Qhov no tseem ceeb heev rauDej Kab Tubing, raws li nws kom ntseeg tau tias cov dej xa tuaj yeem ntxuav thiab pub dawb.

    Ntxiv nrog rau corrosion resistance, ob npaug submerged arc welded kav welded muaj cov khoom siv zoo heev. Cov qauv no tsim cov khoom siv tsis zoo thiab muaj cov yeeb nkab muaj zog thiab txhim khu kev qha. Qhov no yog qhov tseem ceeb rau cov roj nkev uas yog qhov ua kom muaj kev nyab xeeb thiab kev thauj khoom zoo ntawm cov roj nkev tsis muaj kev pheej hmoo ntawm cov dej xau lossis ua tsis tiav.

    Ssaw yeeb nkab

    Ib qho ntxiv, ob chav submerged arc welded kav dej muaj peev xwm tiv taus huab cua sov thiab ib puag ncig. Qhov no ua rau lawv zoo tagnrho rau onshore thiab ntug dej caw uas tuaj yeem raug huab cua hnyav thiab kev ua haujlwm. Rau cov dej kab tubing, qhov tsis txaus ntseeg ua kom cov kav dej tuaj yeem txav cov dej ua tau zoo yam tsis muaj kev cuam tshuam ua tau zoo.

    Lwm qhov zoo dua ntawm kev siv ob tog submerged arc welded yeeb nkab yog tias nws nto yog du thiab zoo nkauj. Qhov no ua rau lawv qhov kev xaiv txaus nyiam rau saum toj- thiab qis dua-hauv kev sib sau, raws li lawv yooj yim tshuaj ntsuam thiab tswj hwm. Tsis tas li ntawd, du nto ntawm Weld txo kev sib txhuam thiab siab nyob rau hauv cov yeeb nkab, pab txhim kho kev txuag roj ntau thiab dej.

    Hauv kev xaus, ob chav submerged arc Welded yeeb nkab yog qhov kev xaiv zoo rauRoj Kab Yeeb Nkabthiab dej kab tubing. Nws cov txheej txheem vuam ua tau zoo thiab raug tsim txiaj, txuas nrog corrosion tsis kam, cov neeg kho kom zoo thiab zoo nkauj, ua thawj qho kev xaiv rau kev tsim kho pipeline. Seb puas kam thauj cov pa roj lossis dej uas muab lub zog thiab kev ntseeg tau xav tau los ua haujlwm nyab xeeb thiab zoo. Kom meej meej, ob-txheej submered arc Welded yeeb nkab yog ib lub cuab tam muaj txiaj ntsig nyob rau hauv lub ntiaj teb kev tsim kho.
