摘要
为了排除牺牲阳极在埋地管道外防腐层检测中的干扰,提出了一种基于密间隔电位测试技术(CIPS)检测含牺牲阳极钢质埋地管道外防腐层状况的方法,介绍了工程检测实例。结果证明,该方法能对管道外防腐层破损点进行辨别,排除牺牲阳极的干扰,并且完成了管道阴极保护效果的检测。
In order to eliminate the interference of sacrificial anode in the detection of anticorrosive coating in buried pipelines,a method based on close interval potential survey( CIPS) was proposed to detect the anticorrosive coating of steel buried pipelines containing sacrificial anode,an example of engineering inspection was introduced. The results show that the method can identify the breakage points of the anticorrosive coating,so that eliminate the interference of sacrificial anode,also achieve the detection of cathodic protection effect of pipelines.
