Experiments to Explore the Decrease of Stray Current Interference from Cathode Protection

采用实验室模拟的方法，研究在管线交叉处使用牺牲阳极和涂层保护两种措施的实验效果，将两种措施减小或消除来自阴极保护设施杂散电流干扰的实验效果与用计算机软件ANSYS模拟的结果进行比较，进而为消除来自阴极保护设施杂散电流对交叉管线的腐蚀影响提供一定的科学地依据。 This paper adopts the method of laboratory simulation to research the effect that using anode in intersections and using coating have on reducing or eliminating the interference of stray current from cathodic protection facilities, and compares the experiment results with the results of computer simulation software ANSYS. Then, this paper provides some scientific basis for eliminateing stray current corrosion influence from cathodic protection facilities to cross pipeline.
