列管式换热器的泄漏分析及防漏措施

Leakage analysis and prevent leakage measures of tube heat exchanger

不同类型的换热器在投入使用数月后,部分换热管与管板连接处发生泄漏。阐述列管式换热器泄漏的事例,从设计、制造、操作三方面分析泄漏的原因和应采取的预防措施,为今后换热器的设计、制造和使用提供参考。

Different types of heat exchanger was put into use a few months later, leakage at heat exchange tube and tube plate junction. Elaborate tubular heat exchanger leak cases, from the design, manufacture, operation analysis of the causes for the leakage and the preventive measures should be taken. In future, provide reference for the heat exchanger design, manufacture and use.
