基于检查片的埋地管道阴极保护检测与评估

摘要

阴极保护作为埋地管道的主要防护措施，在管道保护方面起到重要作用。为了准确地评估管道阴极保护效果，文中介绍了管道阴极保护检查片检测技术，重点阐述了国内外发展状况以及利用检查片检测管道阴极保护效果的优势，分析了目前国外对检查片检测技术的改进方式和评价准则，对埋地管道阴极保护检查片检测评估技术提出了展望，并成功应用于某长输管道阴极保护的检测与评估。%As the main protection of buried pipelines, cathodic protection played an important role in the pipeline protec-tion. In order to accurately assess the pipeline cathodic protection, detection technology of cathodic protection by coupon was de-scribed in this article. The development status at home and abroad and the advantage of use coupon to detect the pipeline cathodic were expounded. The improvement mode and evaluation criteria of checking coupon technology, some prospects are put forwards to detection and effective evaluation technology by coupon for buried pipelines, and it is successfully applied to the detection and assessment of cathodic protection of pipeline.
