1. Vuam txheej txheem
Ib qho ntawm cov txheej txheem tseem ceeb ntawm X52 pipeline yog vuam. Cov txheej txheem vuam muaj xws li hluav taws xob vuam, roj vuam, submerged arc vuam, thiab lwm yam. Hluav taws xob vuam yog tsim kom muaj qhov kub thiab txias ntawm vuam pas nrig thiab workpiece los ntawm qhov kev txiav txim ntawm hluav taws xob tam sim no, kom nws melts thiab txias los ua ib tug weld. Gas welding yog siv lub siab kub ntawm cov roj welding torch nplaim kom yaj qhov chaw ntawm lub workpiece thiab txias nws los ua ib tug weld. Submerged arc vuam yog kom sov lub workpiece thiab vuam pas nrig los ntawm hluav taws xob arc, kom nws melts thiab txias los tsim ib tug weld. Cov txheej txheem vuam tuaj yeem paub txog kev sib txuas thiab kho cov kav dej X52.
2. Txiav txim qhov loj
Hauv cov txheej txheem tsim khoom ntawm X52 pipeline, nws yog ib qho tsim nyog los txiav txim siab qhov loj ntawm cov kav dej raws li cov qauv tsim. Ua ntej, sab nraud txoj kab uas hla, phab ntsa thickness thiab ntev ntawm cov kav dej yuav tsum tau txiav txim siab. Lub sab nraud txiav txim siab txoj kab uas hla ntawm lub raj xa dej, phab ntsa thickness txiav txim siab lub zog ntawm cov kav dej, thiab qhov ntev txiav txim siab qhov kev siv ntawm cov kav dej. Tom qab qhov loj me yog txiav txim siab, cov txheej txheem ntau lawm tom ntej tuaj yeem ua tiav.
3. Cov txheej txheem yeeb nkab dabtsi yog khoov
Hauv kev tsim cov kav dej X52, feem ntau yuav tsum tau khoov cov kav dej. Cov yeeb nkab dabtsi yog khoov txheej txheem tuaj yeem ua tiav los ntawm kev khoov txias lossis kub dabtsi yog khoov. Kev khoov txias yog khoov cov yeeb nkab ntawm chav tsev kub thiab haum rau cov ntaub ntawv hloov tau yooj yim. Kub dabtsi yog khoov yog khoov cov yeeb nkab ntawm qhov kub thiab txias thiab haum rau cov ntaub ntawv nyuaj.
4. Kev kho deg
Kev kho saum npoo ntawm X52 pipeline yeeb nkab yog los tiv thaiv cov yeeb nkab los ntawm corrosion thiab hnav. Cov txheej txheem kho saum npoo feem ntau suav nrog kev txau, galvanizing, sandblasting, thiab lwm yam. Kev txau yog txau cov txheej tiv thaiv ntawm cov yeeb nkab kom ua lub luag haujlwm tiv thaiv corrosion thiab tiv thaiv. Galvanizing yog muab tso rau hauv cov yeeb nkab hauv molten zinc los ua zinc txheej los tiv thaiv cov yeeb nkab los ntawm corrosion. Sandblasting yog tshem tawm cov xeb thiab av ntawm qhov chaw ntawm cov yeeb nkab los ntawm lub tshuab sandblasting los ua kom lub ntsej muag smoother.
5. Kev tshuaj xyuas zoo
Thaum lub sij hawm tsim cov txheej txheem ntawm X52 pipeline yeeb nkab, yuav tsum tau soj ntsuam zoo. Kev soj ntsuam zoo tuaj yeem suav nrog kev tshuaj xyuas zoo li, ntsuas qhov ntsuas, ntsuas cov cuab yeej cuab yeej, thiab lwm yam. Kev tshuaj xyuas zoo tuaj yeem ua kom ntseeg tau tias cov kav dej zoo raws li cov qauv tsim thiab muaj kev ruaj ntseg zoo.
6. Kev teeb tsa thiab kev saib xyuas
Cov txheej txheem tsim khoom ntawm X52 cov kav dej yeeb nkab suav nrog tsis yog cov txheej txheem tsim khoom nkaus xwb, tab sis kuj tseem txhim kho thiab kho. Cov txheej txheem kev teeb tsa yuav tsum tau teeb tsa thiab kev sib txuas ntawm cov kav dej raws li qhov tsim nyog. Cov txheej txheem txij nkawm suav nrog kev tshuaj xyuas tsis tu ncua ntawm kev ua haujlwm ntawm cov kav dej, tu thiab kho.
