摘要
目前管道支线越来越多,而部分管道支线铺设时并未设置绝缘装置,这造成了管道阴极保达不到标准要求,本文通过馈电实验及PCM漏电率法验证了支线管道电流流失情况,并在整改后管道阴极保护效果有明显改善,达到标准要求.
Abstract
At present,there are more and more pipeline branches,and some pipeline branches are laid without insulation devices,which results in the cathodic protection of pipelines not meeting the standard requirements.This article verifies the current loss situation of branch pipelines through feeding experiments and PCM leakage rate method,After rectification,the cathodic protection effect of the pipeline has significantly improved,meeting the standard requirements.
