寬流道板式換熱器在石油化工行業中的應用是十分廣泛的，其重要性也是顯而宜見的，換熱設備利用率的高低直接影響到煉油工藝的效率以及成本的費用問題。山西熱水機組廠家據統計換熱器在化工建設中約占投資的1/5。因此，換熱器的利用率及壽命是值得研究的重要問題。由寬流道板式換熱器的損壞原因來看,腐蝕是一個十分重要的原因，而且換熱器的腐蝕是大量的普遍存在的，能夠解決好腐蝕問題，就等于解決了換熱器損壞的根本。熱水機組廠家在(zai)(zai)周(zhou)圍(wei)介(jie)質(zhi)的(de)(de)(de)化學(xue)或電化學(xue)的(de)(de)(de)作(zuo)用(yong)下，并且(qie)經(jing)常是在(zai)(zai)和(he)物理、機械或生(sheng)物學(xue)因素的(de)(de)(de)共同作(zuo)用(yong)下金屬(shu)產生(sheng)的(de)(de)(de)破壞(huai)，也即金屬(shu)在(zai)(zai)它所(suo)處環境(jing)的(de)(de)(de)作(zuo)用(yong)下所(suo)產生(sheng)破壞(huai)。列管式換熱器(qi)在(zai)(zai)制(zhi)作(zuo)時(shi)，管板與列管的(de)(de)(de)焊接一般(ban)采用(yong)手工電弧焊，焊縫(feng)形狀存在(zai)(zai)不同程度的(de)(de)(de)缺陷，如(ru)凹陷、氣孔、夾渣等，焊縫(feng)應力的(de)(de)(de)分(fen)布也不均勻(yun)。
