基于CIPS检测杂散电流对埋地钢质燃气管道的影响

文中介绍了密间隔电位（CIPS）检测技术及其原理，分析了直流杂散电流及其对埋地钢质燃气管道的腐蚀机理，利用密间隔电位检测技术对某段埋地钢质燃气管道进行了检测与数据分析，评价了该段埋地钢质燃气管道附近杂散电流对埋地钢质燃气管道的影响，为相关燃气管道的检测提供了参考案例。

Based on CIPS Detection Stray Current Effect on Buried Steel Gas Pipeline

This paper introduces the close interval pipeline survey （CIPS）detection technology and its principle, analyzes the DC stray current and the corrosion of a buried steel gas pipeline and by way of the project example, makes use of the close inter- val pipeline survey （CIPS） detection technology to detect a buried steel gas pipeline and analyzes its data. At the same time, it e- valuates the effect caused by the stray current nearby on the buried steel gas pipeline providing some preferable reference for the detection of relevant gas pipelines.
