Kauv welded carbon steel yeeb nkab, xws li S235 JR thiabX70 SSAW kab yeeb nkab, yog qhov kev xaiv nrov rau cov kav dej hauv av vim nws cov kav ntev thiab corrosion kuj.Cov kav dej yog tsim los siv cov txheej txheem welding, kom ntseeg tau tias muaj zog thiab cov qauv muaj peev xwm tiv taus cov kev ntxhov siab thiab ib puag ncig cuam tshuam nrog kev thauj mus los hauv av.Tsis tas li ntawd, cov kav dej no tau tsim los ntawm cov pa roj carbon zoo rau lub zog zoo dua thiab siv tau ntev, ua rau lawv muaj kev ntseeg siab rau cov dej xa dej mus sij hawm ntev.
Ib qho ntawm qhov zoo ntawm kev sivkauv welded carbon steel kavrau kev thauj mus los hauv av yog nws cov corrosion kuj.Cov kav dej hauv av tas li raug cov dej noo thiab lwm yam ib puag ncig, uas tuaj yeem ua rau cov khoom siv ib txwm muaj xws li pob zeb lossis PVC kom xeb thiab tsis zoo.Txawm li cas los xij, cov pa roj carbon steel yeeb nkab muaj qhov tiv taus corrosion heev, kom ntseeg tau tias lawv tuav lawv cov qauv kev ncaj ncees nyob rau lub sijhawm.Qhov kev tiv thaiv corrosion no txo cov kev xav tau ntawm kev tu thiab hloov, thaum kawg txuag cov nqi dej.
Tsis tas li ntawd, lub zog thiab kav ntev ntawm kauv welded carbon steel yeeb nkab ua rau nws zoo tagnrho rau kev teeb tsa hauv av.Cov kav dej no muaj peev xwm tiv taus sab nraud los ntawm cov av thiab lwm yam hauv av, kom ntseeg tau tias lawv nyob twj ywm thiab ua haujlwm tau zoo thoob plaws hauv lawv lub neej kev pabcuam.Tsis tas li ntawd, nws txoj kev tsim kho thiab cov chaw sab hauv du txo qhov kev pheej hmoo ntawm kev thaiv los yog xau, ua rau muaj kev ntseeg siab ntxiv thiab kev ua haujlwm ntawm kev thauj dej hauv av.
Hauv cov ntsiab lus,cov kav dej hauv avyog ib qho tseem ceeb ntawm cov txheej txheem niaj hnub no, thiab kev xaiv cov khoom siv hauv cov kav dej no yog qhov tseem ceeb rau lawv txoj kev ua tau zoo thiab kev ua haujlwm ntev.Kauv welded carbon steel yeeb nkab, xws li S235 JR thiab X70 SSAW kab yeeb nkab, muaj ntau yam zoo rau kev thauj mus los hauv av, suav nrog kev ua haujlwm zoo dua, kev tiv thaiv corrosion thiab siab zog.Los ntawm kev siv cov kav dej zoo, cov kav dej tuaj yeem ua kom ntseeg tau, xa dej mus rau cov zej zog kom txo qis qhov xav tau kev saib xyuas thiab hloov pauv.
