超期服役管壳式换热器检验检测方法探讨

Discussion on the Inspection Methods of Shell and Tube Heat Exchanger Extended Service

压力容器超期服役存在一定的运行风险,现行规范暂无明确的检验检测标准规范,导致超期服役的压力容器检验存在不规范且无执行标准的现象。以管壳式换热器为例,探讨了超期服役的管壳式换热器检验检测方法,为超期服役的压力容器检验提供一定的参考。

The overdue service of pressure vessels has certain operational risks.The current regulations have no clear inspection and testing standards,which leads to irregularities and no implementation standards in the inspection of pressure vessels overdue service.Taking shell-and-tube heat exchangers as an example,this article discusses the inspection methods of shell-and-tube heat exchangers that have been over-serviced,and provides a reference for the inspection of pressure vessels that have been over-serviced.
