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。寧波熱交換器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。熱交換器廠家在(zai)(zai)周圍介質的(de)化學或(huo)電化學的(de)作用(yong)下(xia)，并且經常是在(zai)(zai)和物理、機械或(huo)生物學因素的(de)共同作用(yong)下(xia)金(jin)屬產生的(de)破壞(huai)，也(ye)即金(jin)屬在(zai)(zai)它所處環境的(de)作用(yong)下(xia)所產生破壞(huai)。列管(guan)式換熱(re)器在(zai)(zai)制作時，管(guan)板(ban)與列管(guan)的(de)焊(han)接(jie)一(yi)般采用(yong)手(shou)工電弧焊(han)，焊(han)縫(feng)形狀存在(zai)(zai)不同程度(du)的(de)缺陷，如凹(ao)陷、氣孔、夾渣等，焊(han)縫(feng)應力的(de)分(fen)布也(ye)不均勻。
