摘 要(yao) :殼式換(huan)熱(re)(re)器(qi)由于管內(nei)外流體(ti)(ti)的(de)溫(wen)度(du)不(bu)同,因之換(huan)熱(re)(re)器(qi)的(de)殼體(ti)(ti)與(yu)管束的(de)溫(wen)度(du)也不(bu)同。如果(guo)兩溫(wen)度(du)相差(cha)很(hen)(hen)大,換(huan)熱(re)(re)器(qi)內(nei)將(jiang)產生很(hen)(hen)大熱(re)(re)應力,導(dao)致管子彎曲、斷裂(lie),或從管板上拉脫。因此,當(dang)管束與(yu)殼體(ti)(ti)溫(wen)度(du)差(cha)超過(guo)50℃時,需采取適(shi)當(dang)補償措施(shi),以(yi)消除或減(jian)少熱(re)(re)應力。根據所采用的(de)補償措施(shi),管殼式換(huan)熱(re)(re)器(qi)可分為以(yi)下(xia)幾種
