浅谈管壳式热交换器制造工艺关键控制点

Discussion to Critical Control Points for Manufacturing Process of Shell-and-tube Heat Exchanger

通过采取有效工艺措施,保证管接头焊接和胀接质量,减少管板变形产生的应力,可以减少热交换器在使用过程中由于管接头焊缝开裂和渗漏发生的设备故障。

This paper introduces that through adopting effective technical measures, ensuring the quality of welding and expanding of pipe joints, reducing stress produced by the deformation of tube sheet, it can reduce the heat-exchanger in service occurred equipment failure by reason of pipe welding crack and leakage.
