| Abstract: | Integrity testing of coating is the key to ensuring effective soil with the pipe insulation,improve the effectiveness of the cathodic protection.The paper analyzes the commonly used anti-corrosion layer of buried steel pipeline damage detection technical features,by combining on-site inspection practices,and integrates the applications of multiple technologies that can detect the point of buried steel pipeline coating damages.Based on the measurement data,the size of the damaged points can be judged,and whether excavation and repair has begun,so as to find the point of integration between safe operation and economy. |
