摘要
阴极保护电流密度既是阴极保护系统的主要控制参数,又是衡量防腐涂层绝缘性能的重要指标,它可以非常好的反应阴极保护及管道防腐层的工作状况。本文详细介绍了目前国内外采用的几种阴极保护电流密度测试方法,重点分析了它们在不同防腐层管道上的适用性,并对测试方法的改进和创新提出建议。
Cathodic protection current density is one of the main control parameters for cathodic protection system and also an important indicator to measure anti-corrosion coating insulating performance, so that it could be very good response to the working conditions of the pipeline coating and cathodic protection. This paper particularly introduces several domestic and foreign test methods of cathodic protection current density in present, focuses on analyzing these methods＇ applicability on different coating pipelines, and makes recommendations to improvement and innovation of these methods.
