摘要
阐明换热器管束完整性评价的概念及意义。根据换热器管束损伤机理及缺陷类型,分别综述了换热管剩余强度评价技术、剩余寿命预测技术及其堵管准则的研究进展。结合工程实际,简要介绍了完整性评价技术在炼化企业换热器管理维护中的应用现状和存在的问题。对推进完整性评价技术在换热管束方面的进一步应用提供依据,并探讨了需重点解决的几个问题。
Integrity assessment of heat exchanger tube includes residual strength life assessment, which were discussed respectively according to heat exchanger damage assessment and residual tube defect types and its mechanism. As an application form of integrity assessment technology, the heat exchanger tube
