Cov txheej txheem arc vuam yog qhov tseem ceeb hauv kev tsim cov kauv wird welded yeeb nkab, tshwj xeeb tshaj yog rau cov pa roj pipelines. Cov cuab yeej thev naus laus zis los tsim cov kav dej muaj zog thiab ruaj khov uas cov kav dej tuaj yeem tiv thaiv cov kev thov sib tsoo. Txawm li cas los xij, zoo li ib qho txheej txheem tsim khoom, arc vuam nws muaj nws cov kev cov nyom. Cov pipeline vuam puas muaj qhov tsis xws luag muaj peev xwm ua kom muaj kev ncaj ncees ntawm Weld, ua rau muaj kev ua tsis tiav hauv lub tshav pob. Nkag siab cov kev tsis xws luag thiab siv cov kev ntsuas tiv thaiv yog qhov tseem ceeb rau cov chaw tsim khoom, tshwj xeeb yog cov tuam txhab, uas tau muaj tus thawj coj hauv kev lag luam txij xyoo 1993.
Cov Yeeb Nkab Siv Weld Tsis Zoo
1. Porosity: Qhov tsis haum no tshwm sim thaum cov hnab tshos cua nyob hauv Weld, tsis muaj zog ntawm Weld. Porosity tuaj yeem tshwm sim los ntawm kev sib kis, noo noo, lossis cov txheej txheem improtic.
2. Undercut: Thaum tus niam txiv hlau ntawm ntug ntawm tus weld melts, ib tug zawj yog tsim, tsis muaj zog ntawm Weld. Qhov no feem ntau yog tshwm sim los ntawm overheating los yog tsis yog vuam ceev.
3. Kev suav nrog: Cov no yog cov ntaub ntawv tsis yog xim hlau uas tau ntes tau hauv Weld thiab tsis muaj zog ntawm Weld. Suav nrog tuaj yeem tawm los ntawm slag lossis lwm yam paug tsis tau muab tshem tawm kom raug tshem tawm tau zoo ua ntej vuam.
4. Kev tawg: cov kab nrib pleb yuav tshwm sim hauvTube WeldThaj chaw kub lossis kub-cuam tshuam rau kev ua kom txias sai sai, tsis tsim nyog muab cov khoom siv tsis tsim nyog lossis siv weld ntau dhau.
5. Qhov no tuaj yeem tshwm sim los ntawm cov txheej txheem kub tsis txaus lossis cov txheej txheem improtique.
Yuav ua li cas tiv thaiv vuam tsis xws luag
Tiv thaiv cov yeeb nkab sib txuas no yuav tsum muaj kev cob qhia kev ua haujlwm zoo, kev kho khoom siv, thiab kev ua raws li kev coj ua zoo tshaj plaws. Ntawm no yog qee cov tswv yim koj tuaj yeem siv:
1. Kev kawm kom zoo: nws yog qhov tseem ceeb los xyuas kom meej tias koj cov welders tau kawm zoo hauv Arc Vuam cov txheej txheem. Kev cob qhia tsis tu ncua tuaj yeem pab ua kom lawv ua raws li cov kev coj ua thiab cov tswv yim tshiab.
2. Tswjhwm Zoo: Kev siv cov kev tswj kom muaj zog ua kom kuaj pom thaum ntxov hauv kev tsim khoom. Kev tshuaj xyuas ib txwm thiab kuaj ntawm cov teeb meem welds tuaj yeem tshawb xyuas teeb meem ua ntej lawv tsim tawm rau hauv cov teeb meem loj.
3. Cov Khoom Siv Tu Siab: Kev Tu Cov Khoom Siv Vuam Vuam yog qhov tseem ceeb kom ntseeg tau tias kev ua tau zoo tshaj plaws. Qhov no suav nrog kev kuaj xyuas kom muaj kev ntsuas kom raug, kev ntxuav tu, thiab hloov cov chaw hnav.
4. Khoom npaj: Kev npaj tsim nyog ntawm cov ntaub ntawv ua ntej vuam yuav txo qis kev pheej hmoo ntawm qhov tsis xws luag. Qhov no suav nrog kev ntxuav cov npoo kom tshem tawm cov paug tsis huv thiab ua kom cov khoom siv tau qhuav.
5. Tshuaj tiv thaiv ib puag ncig: soldering nyob rau hauv ib puag ncig ib puag ncig tuaj yeem pab txo qis kev pheej hmoo ntawm cov tsis xws luag los ntawm lwm tus kub thiab av noo.
6. Siv cov ntaub ntawv zoo: Kev yuav Khoom Siv Vuam Khoom Siv Tau Zoo tuaj yeem txo qhov kev tsis xws luag. Qhov no suav nrog kev siv cov khoom siv ua kom tsim nyog thiab ua kom cov txiv niam txiv ua tau raws li cov lus qhia kom raug.
Peb cov nroj tsuag hauv Cangzhou ua 400,000 tons ntawm KAUV HLAU PIPES ib xyoos nrog 680 cov neeg tau mob siab. Peb cov kev cog lus rau kev ua tau zoo thiab ua kom muaj kev tsim kho peb ntawm qhov ua ntej ntawm kev lag luam. Los ntawm kev tsom mus rau kev tiv thaiv cov yeeb nkab vuam tsis xws luag, peb paub tseeb tias peb cov kauv hluav taws xob roj, tshwj xeeb tshaj yog cov siv roj av muaj kev ntseeg siab thiab cov qauv kev ua tau zoo.
Hauv cov ntsiab lus, kev nkag siab txog cov yeeb nkab vuam tsis xws luag thiab siv cov kev ntsuas tiv thaiv yog qhov tseem ceeb rau cov neeg tsim khoom siv hauv cov yeeb nkab hluav taws xob. Los ntawm kev ua ntej zoo thiab kev cob qhia, cov tuam txhab tuaj yeem tsim cov khoom ruaj khov, muaj peev xwm txhim khu kev qha uas sawv ntawm lub sijhawm.
