Ordinary heat exchangers txais cov carbon steel los yog cov qauv hlau tsis tu ncua. Lawv yuav raug kev txom nyem pitting corrosion, xeb thiab perforation thaum raug corrosive nruab nrab, uas hem tag nrho cov kab ntau lawm. Nws yog qhov tsim nyog sivcorrosion resistant tshav kub exchangerrau cov xwm txheej ua haujlwm tshwj xeeb. Raws li cov chaw tsim khoom lag luam, peb txheeb xyuas cov xwm txheej uas siv tau.
Kev tsim tshuaj lom neeg yog qhov tseem ceeb ntawm daim ntawv thov. Cov txheej txheem dej muaj cov kua qaub, alkali thiab ntau yam tshuaj ntsev. Cov cuab yeej siv hluav taws xob sib hloov pauv yuav raug corroded sai. Kev kho cov dej khib nyiab kuj tseem xav tau cov cuab yeej tiv thaiv corrosion. Cov dej khib nyiab nqa chloride ion, organic impurity thiab corrosive ion. Kev ua haujlwm mus sij hawm ntev yuav ua kom puas cov hlau nto. Seawater thiab brine txias system belongs rau high-chloride ua hauj lwm mob. Chloride ion yooj yim ua rau pitting corrosion ntawm cov hlau zoo tib yam. Qee cov txheej txheem metallurgical thiab mining tsim cov txheej txheem corrosive kua, uas yuav ua rau luv luv kev pabcuam ntawm cov khoom siv.
Yog hais tias qhov nruab nrab muaj corrosive Cheebtsam, los yog ua hauj lwm ib puag ncig muaj humid ntsev pos huab, corrosion yuav tsis raug ignored. Kev siv cov khoom siv hluav taws xob zoo tib yam yuav ua rau muaj kev saib xyuas tsis tu ncua, muaj feem cuam tshuam thiab tsis npaj kaw. Txawm hais tias corrosion kos npe tsis pom tseeb nyob rau theem pib, qhov kev puas tsuaj zais zais yuav sib sau ua ntu zus. Cov neeg siv khoom yuav tsum ntsuas qhov kev pheej hmoo corrosion nyob rau theem pib tsim qhov project. Peb txhawb kev ntsuam xyuas qhov project, thiab muab cov khoom siv hluav taws xob tiv thaiv corrosion rau kev ua haujlwm siab ua haujlwm kom ruaj khov nruam ntau lawm.
