摘要
本文主要介绍关于外加电流阴极保护技术应用于长输埋地的钢质管道中,但是因为穿越每段管段的保护电流受损十分严重,致使部分山体的土壤电阻率增加,使得流向管道内部的保护电流逐渐减少,导致某一部位的管道不能得到很好的保护。本文就华东某成品油管道进行阐述。
This paper mainly introduces the impressed current cathodic protection technology used in long distance buried steel pipeline, but because of the cross section of each protection current damage is very serious, which part of the mountain of soil resistivity increase, makes the flow inside the pipeline protection current gradually reduce, lead to a certain parts of the pipe can't get good protection. This paper describes a product oil pipeline in east China.
