摘　　要：本文对磁应力管道检测与评价技术的原理及特点进行了概述,并在新疆某集油系统的站间管线上成功进行了现场检测工作。检测结果表明,该检测技术能够在不开挖的情况下直接检测管道本体缺陷,对于不能进行常规内检测的埋地管道是非常有效的检测技术。In this paper,the principle and characteristics of magnetic stress inspection technique is introduced,and the field testing work is successfully carried out in the crude oil gathering pipeline between the metering stations in Xinjiang.According to the testing results,it shows that the detection technology can directly detect the defects of the pipeline without excavation.This is a very effective detection technique for buried pipelines that can not be routinely ELI tested.

关 键 词：应力集中区 磁应力检测技术 埋地管道
