管殼式換熱器是石油化工行業的重要設備，四川板式換熱器廠家它的腐蝕及保護對設備的長周期運行有著重要的意義；由于近年來加工原油中的硫、酸及雜質含量越來越高，對煉油換熱設備的防腐蝕性能及材料的選擇提出了更高的要求。文章對采用專用涂料與犧牲陽極綜合保護法進行了闡述，該方法工藝方案和特點是：管殼式換熱器的工藝方案和特點是什么表面處理要徹底，合理選取保護電流密度，按設計要求確定陽極塊，控制好濕度和溫度，涂料施工嚴格按照SHY－99涂料工藝進行，確保綜合防護的效果。板式換熱器目前國內(nei)石(shi)油(you)、化纖、冶金、發(fa)電等企業(ye)的(de)冷換器設備經常由于水垢(gou)、腐(fu)蝕產物和腐(fu)蝕物黏泥造成(cheng)冷換器堵塞，致傳熱(re)系數下降，是(shi)冷卻水系統中常見的(de)問題。由于碳酸(suan)鹽垢(gou)的(de)導熱(re)系數只有碳鋼的(de)1%左右(you)，直接影響到(dao)了換熱(re)效率，增加了系統的(de)壓力降。
