摘　　要：针对多起超过设计服役年限的压力式除氧器水箱经常出现规律性开裂并引起泄漏的问题,介绍了对带有三角形加强圈的压力式除氧器的强度校核与缺陷修复,分析了缺陷产生原因,提出了监控运行措施,为同类设备缺陷的检验和安全运行提供了参考。In order to solve the problem of regular cracking and leaking of water tank in pressure deaerators over designed service lives, the examination, calculation and repair of deaerator with triangle reinforcement ring structures are introduced. The reasons of cracking and leaking are analyzed and suggestions are proposed for supervising future operation, which could be used as references for defect examination and safety operation of similar deaerators.
