摘要
汽包是锅炉中的重要部件,但是汽包在制造和运行过程中不可避免会产生缺陷,这就需要对带裂纹汽包进行安全性检测。本文介绍了几种基于"合计使用"原则、用于检测带缺陷汽包的理论方法与步骤,并且对带裂纹汽包的使用寿命进行了探讨。
Drum is an important part of boiler, but it is unavoidable bring flaws in the process of manufacture and operation, so Security Evaluation is needed. The paper introduces the assessment methods and working steps based on ＂Fitness For Service＂ principle, and discusses the service life of drum contains flaws.
