摘要
本文主要讲述了深井阳极外加电流阴极保护系统在石化化纤厂区埋地循环冷水、循环回水、生产新鲜水管线上的应用。采用深井式混合金属氧化物阳极作为辅助阳极地床,可控硅恒电位仪为系统电源,长效硫酸铜参比电极作为信号反馈电极,沿线设置测试桩用于监测阴极保护效果,阴极保护投产运行后,整条管道阴极保护效果良好。
This article described the application of ICCP system for buried water pipeline including circulating cooling water pipeline,circulating water and fresh water pipeline in petrochemical plant area.Mixed metal oxide anode was used as auxiliary anode ground bed in the deep well,Silicon controlled rectifier provided power source,long-acting copper sulfate reference electrode was used as a signal feedback electrode.Test piles were arranged along the line to monitor the effect of cathodic protection.After the ICCP system was used,the pipe line was in good cathodic protection state.
