Vim nws daim ntawv thov dav dav ntawm cov kav dej loj-diameter kauv hlau, nws feem ntau muab tso rau sab nraum zoov thiab faus ntau lub sijhawm, yog li nws yooj yim cuam tshuam los ntawm corrosion thiab xeb. Txhawm rau kom ntseeg tau tias cov kav dej tsis muaj kev cuam tshuam, cov kav hlau kav yuav tsum muaj kev tiv thaiv corrosion siab. Thaum lub raj xa dej tau corroded, nws yuav ua rau cov roj thiab qi to. Nws yuav tsis tsuas cuam tshuam kev thauj mus los, tab sis kuj ua rau ib puag ncig, thiab tseem ua rau hluav taws, ua rau muaj kev puas tsuaj loj.
Ua ntej, cov xwm txheej sab nraud yog qhov tseem ceeb cuam tshuam rau corrosion ntawm kauv steel raj. Cov yam ntxwv, qhov kub thiab txias ib puag ncig ntawm lub raj xa dej tuaj yeem cuam tshuam corrosiveness. Hauv particular, cov kab mob thiab cov tshuaj nyob rau hauv cov av ncaj qha cuam tshuam rau corrosion ntawm cov kav dej. Tsis tas li ntawd, ib puag ncig ntawm cov kav dej ntev ntev yog qhov nyuaj thiab xav tau kev saib xyuas tshwj xeeb. Tsis tas li ntawd, qhov kub ntawm ib puag ncig ntawm cov raj xa dej kuj cuam tshuam rau corrosion ceev ntawm kauv steel yeeb nkab. Qhov kub thiab txias yuav ua kom cov txheej txheem corrosion, thiab qhov kub qis yuav ua rau qeeb ntawm corrosion.
Thib ob, kev tiv thaiv corrosion tsis ua hauj lwm yog lwm qhov laj thawj tseem ceeb rau corrosion ntawm kauv steel raj. Yog tias cov kav hlau kav tsis ua haujlwm zoo hauv cov txheej txheem ntawm kev tso, lossis xaiv cov khoom siv tiv thaiv tsis zoo, nws yuav ua rau cov txheej txheem tiv thaiv corrosion tsis ua haujlwm, uas ua rau cov kav dej txuas ncaj qha rau sab nraud ib puag ncig thiab ua kom cov txheej txheem corrosion. Yog li ntawd, thaum tso ib kauv steel yeeb nkab, kev tiv thaiv corrosion yuav tsum tau txiav txim siab thiab kev ncaj ncees ntawm cov txheej txheem anticorrosive yuav tsum tau ua kom ntseeg tau.
Txhawm rau tiv thaiv corrosion thiab xeb ntawm kauv steel kav, qee qhov kev tiv thaiv corrosion zoo tuaj yeem siv. Piv txwv li, ntxiv anticorrosive txheej thaum lub sij hawm tsim khoom, xws li polyethylene los yog polyurethane, los txhim kho nws corrosion kuj. Tsis tas li ntawd, kev tiv thaiv cathode tuaj yeem siv los tiv thaiv cov kauv hlau yeeb nkab los ntawm kev tiv thaiv los ntawm kev tiv thaiv cov txheej txheem tam sim no lossis kev txi anode.
