Long distance pipeline is usually buried about 1.5 meters underground. The terrain of the line is very complex, including desert, Gobi, plateau, mountain area, water network and plain. There are various kinds of crossing along the pipeline, such as railway and highway. Rivers, tunnels, etc. Therefore, due to the limitation of technical conditions, it is very difficult to test the polarization potential of pipeline.
The disadvantages of the existing power-off potential measurement technology are that the equipment is expensive, the process is cumbersome, and the daily maintenance measurement cannot be realized. In view of this situation, various pipeline research institutions and anti-corrosion equipment manufacturers are committed to the research and test of polarization potential online monitoring, and have achieved certain results.
At present, there are two aspects of progress. One is the cathodic protection online monitoring expert system. At the same time, with the help of the cathodic protection online monitoring expert system, the whole cathodic protection system can be in the best working state and play the role of protection to the maximum extent.
Shandong Linyi Bosi conductive materials Co., Ltd. is a high-tech enterprise specializing in the production of MMO flexible anode, conductive polymer flexible anode and titanium coated anode, mainly providing cathodic protection technology, engineering design, installation and technical services.
