埋地钢质输气管道的检测与评估技术

Detection and Evaluation Technique for Buried Steel Gas Pipeline

针对运行多年的输气管道出现的防腐层龟裂、破损和剥离以及管道承压能力下降的状况 ,提出了以多种检测方法为基础 ,采用相关理论和标准解决管道防腐层问题和对管道的剩余寿命进行评估的方法。认为通过检测与评估技术的应用 ,可以实现管道运行状态的监控 ,保障输气管道的安全运行。

In allusion to the aging, damage and disbonding of coating and lowering load capacity for old gas pipeline,the paper puts forward the methods to solve coating aging problem with relative theory and standard and evaluate residual life of pipeline based on different detection techniques. It is considered that the monitoring of pipeline operation status can be realized to ensure safe operation of gas pipeline through the application of pipeline detection and evaluation technology.
