摘要
防腐蚀层和阴极保护体系是埋地管道系统完整性的重要组成部分。为了让管道检测部门、运营部门掌握埋地长输管道外覆盖层安全质量状况和阴极保护的水平,同时为管道完整性管理提供数据支持,文章通过外防腐蚀层直接评价方法,结合油气管道完整性和检测参量的相关性研究,提出一套外防腐蚀层与阴极保护整体质量状况的检测与评价方案。
The coating and the cathodic protection are two important parts of buried pipeline system. In order to allow pipeline inspection departments, operation sector to know coating safety and quality information of buried long - distance pipeline and performance of cathodic protection and to provide data for pipeline integrity management, an detection and assessment process for the external coating and cathodic protection is presented through ECDA （Pipeline External Corrosion Direct Assessment） and based upon the research on oil ＆ gas pipeline integrity and testing parameters
