摘　　要：CIPS技术是国际最先进的埋地管道外防腐层及阴极保护系统检测评价方法,它能够指示管道沿线的CP效果,有效去除IR电压降的影响,指出缺陷的严重性,并自动采集数据样,是断位测试法、地表参比法的有机结合。该项技术可用于检测管道的阴极保护电位、评价阴极保护效果、了解管道的防护层状况以及进行防护层缺陷检测。CIPS is the best advanced technique of protection coating and cathode protection monitoring method of buried pipelines,it can figure out the effect of pipeline CP,effectively eliminate the impact of IR-drop,point out the severity of fault and takes sample of data automatically.It combines with the interval potential and surface reference techniques,can be used to the check the cathode protection potential of pipeline,assess the effect of cathode protection,find out the status of pipeline protection coating and fault monitoring.

关 键 词：埋地管道检测 阴极保护系统评价 密间隔电位法
