管壳式换热器

  换热器从其功能上来看,一方面是保证工业过程对介质所要求的特定温度,另一方面也是提高能源利用率的主要设备。按其结构形式主要有板式换热器、浮头式换热器、固定管板式换热器和U形管式换热器等等。其中除板式换热器外,其余几种属于管壳式换热器。由于管壳式换热器具有单位体积上较大的换热面积,而且换热效果好,同时具有结构坚固、适应性强、制造工艺成熟等优点,已成为最为普遍使用的一种典型的换热器。

  换热管与管板采用焊接连接时,由于对管板加工要求较低,制造工艺简单,有较好的密封性,并且焊接、外观检查、维修都很方便,是目前管壳式换热器中换热管与管板连接应用最为广泛的一种连接方法。在采用焊接连接时,有保证焊接接头密封性及抗拉脱强度的强度焊和仅保证换热管和管板连接密封性的密封焊。对于强度焊其使用性能有所限制,仅适用于振动较小和无间隙腐蚀的场合。
