管壳式换热器长期作为石油化工装置中最常见的换热器形式，其中换热管已成为制约设备整体使用寿命的重要因素。很多换热管在设备主要受压部件正常使用期间就已出现泄漏，导致需要部分堵塞，甚至更换整个管束或设备。通过实践总结，分析管束的主要泄漏原因，提出优化方案和改进措施。如，换热管经钝化处理后可有效延长换热管使用寿命，提高设备的可靠性和经济性。

The shel and tube heat exchanger for petrochemical instalations is the most commonly used,but the heat exchange tube service life has affected the use of the equipment.Most of the heat exchanger tube during the normal use of main pressure parts has been leaking,and result in block some heat exchange tubes,or even replace the tube bundle or the whole equipment.Through the practice,analysis of main reason of leakage,optimization and improvement measures.For example,the carbon heat exchanger tubes by passivated can effectively prolong the service life of heat exchange tubes,and improve the reliability and economy of the equipment.
