摘要:

在生产中发现，双竹线阴极保护测试电位普遍偏低，不利于有效保护管道。从绝缘层状况、管道搭接、站内阴极保护装置工况、跨接电缆、绝缘法兰等方面进行分析调查，提出整改措施，为今后的生产管理提供了技术支撑。

Abstract:

The cathodic protective potential of the Shuangzhu gathering lines were lower during the course of production and had a bad protection effect to the lines. The investigation and analyzing were carried out according to the conditions of the insulated layer
