Vim tias cov kav dej kauv tau muab tso rau sab nraum zoov, thiab feem ntau ntawm lawv tau faus rau hauv av thaum siv, nws yooj yim rau corrode thiab xeb. Txhawm rau kom ntseeg tau tias qhov dej ntws zoo ntawm cov kav dej, cov kav raj xa dej yuav tsum muaj zog.
Thaum lub raj xa dej tau corroded, nws yuav ua rau cov roj thiab cov pa tawm, tsis yog tsuas yog cuam tshuam kev thauj mus los, tab sis kuj ua rau ib puag ncig, thiab tej zaum yuav ua rau hluav taws kub thiab ua rau muaj kev puas tsuaj. Cov chaw tsim tshuaj paus kauv raj yuav qhia rau koj txog yam uas ua rau kauv raj corrosion:
1. Anti-corrosion tsis zoo. Thaum lub raj xa dej tau tsim, yuav tsum ua haujlwm los tiv thaiv corrosion los yog ncaj qha siv cov kav dej los tiv thaiv corrosive. Yog vim li cas vim li cas lub raj xa dej yog corroded yog tias cov txheej tiv thaiv corrosion ntawm cov kav dej puas. Thaum cov txheej txheem anticorrosive thiab qhov chaw ntawm cov raj xa dej sib cais, cov tshuaj tiv thaiv corrosion yuav ua rau muaj kev tiv thaiv corrosion. Qhov no kuj qhia tau hais tias peb yuav tsum xaiv anticorrosive kauv raj thaum muas ib kauv raj.
2. Kev cuam tshuam ntawm sab nraud. Nws yog qhov tseem ceeb kom pom tias tus yam ntxwv, qhov kub thiab txias, thiab seb cov xov xwm nyob ib ncig ntawm lub raj xa dej puas corrosive ua ntej. Vim tias qhov siab ntawm qhov nruab nrab corrosion yog ze ze rau ntau yam kab mob uas muaj nyob hauv cov av.
Thiab yog hais tias nws yog ib tug ntev-poob pipeline, qhov xwm ntawm cov av ib puag ncig yog complex. Tsis tas li ntawd, qhov kub thiab txias ntawm ib puag ncig qhov chaw ntawm cov kav dej yuav cuam tshuam rau corrosion ntawm lub kauv raj. Yog tias qhov kub thiab txias, qhov ceev ntawm corrosion kuj yuav nce, thiab qhov kub ntawm qhov kub yuav qeeb.
