阴极保护技术在供水管道定向钻穿越中的应用

Application of Cathodic Protection Technology in Directional Drilling of Water Supply Pipeline

本文通过对过北江供水管道定向钻实地考察,设计阴极保护方案。现场通过法兰改造、新增阴保设施、阴保检测,最终建立起良好的阴极保护系统。有了阴极保护技术的加持,降低了供水管道的腐蚀速度,为供水管道的安全运行提供了有力保障。

In this paper,the cathodic protection scheme is designed through the field investigation of the Directional drilling of the water supply pipeline across the Beijiang River.A good cathodic protection system was ultimately established on site through flange renovation,new cathodic protection facilities,and cathodic protection testing.With the support of cathodic protection technology,the corrosion rate of water supply pipelines has been reduced,providing strong guarantees for the safe operation of water supply pipelines.
