高效换热器换热管在工业生产中广泛运用,其工作状况直接影响工业正常生产。利用宏观、微观观察,用X射线分析换热器换热管失效的原因,发现换热管的失效由多种原因造成,主要包括应力腐蚀、温度影响等。本文通过对失效换热管进行检查,分析高效换热器换热管失效原因,并在此基础上,提出预防高效换热器换热管失效的措施。 Efficient heat exchanger tube heat exchanger widely used in industrial production, the working conditions of a direct impact on industrial normal production. Using macroscopic and microscopic observation, X-ray analysis of the heat exchanger tube failure causes and found that the failure of the heat exchanger tube caused by a variety of reasons, including stress corrosion, temperature and so on. This paper examines the failure of the heat exchange tubes and analyzes the reasons for the failure of the heat exchange tubes of the high efficiency heat exchanger. On this basis, the measures to prevent the failure of the heat exchange tubes of the high efficiency heat exchanger are put forward.
