摘要
文章对油气长输管道腐蚀剩余寿命评价方法的研究意义和现状进行了分析,概述了腐蚀剩余寿命评价的几种常用模型,着重介绍了基于剩余强度理论的腐蚀剩余寿命评价模型的建立过程。文章最后结合某厂的工程实例,阐述了腐蚀剩余寿命评价方法在实际中的应用。
This paper analyzes the research significance and status of corrosion residual life evaluation methods of long-distance oil and gas pipelines,outlines several evaluation methods in common use,stressing on the forming course of the corrosion residual life evaluation model based on the residual strength theory.And finally it describes the application of the corrosion residual life evaluation method with an engineering example of a certain factory.
