隔膜式热交换器是新型高温、高压热交换器，与传统热交换器相比具有结构简单、拆装便捷、投资低及制造周期短等优点。隔膜式密封为强制密封，由大螺栓紧固的压盖来承受内压产生的力，通过密封盘与管箱端部的焊接实现密封。壳体端部法兰装配、端部螺纹孔垂直度加工精度高，管板质量较大，可能会形成螺栓孔和螺纹孔上下错位的现象，造成管束穿入困难，介绍了这些制造难点的解决办法。

Diaphragm seals heat exchangers as a new high temperature,and high pressure heat exchangers are flexible,easy accessibility,low investment,short manufacturing cycle compared to the traditional structure.Diaphragm seals,the internal pressure is forced sealing,withstand the force generated by the gland with large bolts,from to seal plate and pipe welding tank to achieve the ends of the seal,the seal is been mandatory.Housing end flange assembly,high-end portion of the threaded hole verticality precision machining is required higher,tube plate heavier,may be formed the dislocation phenomenon between bolt holes and threaded holes down.
