What are the problems of gas pipeline?

Natural gas plays an important role in the development of China's national economy and is an indispensable material to maintain social stability and people's normal production and life. Therefore, cathodic protection of gas transmission pipeline is a very important task.

In the existing gas transmission pipeline, due to the influence of transportation and construction and other reasons, the external anti-corrosion coating of the pipeline is damaged or pinhole is caused, which makes the pipeline contact with the external corrosion environment, resulting in the corrosion of the damaged pipe body and causing damage to the pipeline. The cathodic protection of pipeline is a protective measure for this problem to prevent the pipeline from being corroded.

At present, there are still some problems in the cathodic protection of gas pipelines, which need to take effective measures in time to ensure the safe operation of gas pipelines. The problems of pipeline cathodic protection are mainly reflected in the following aspects:

1. Soil resistivity is low;

2. The quality of external anti-corrosion coating of pipeline is unqualified;

3. Potentiostat equipment aging.

At present, it is very necessary to carry out cathodic protection for gas transmission pipeline, which is the basic condition to extend the service life of the pipeline and ensure the safe operation of the pipeline. However, it should be noted that there are some problems in the current cathodic protection. The cathodic protection of gas transmission pipeline is a systematic project, which includes many aspects, including the cathodic protection of the pipeline itself, the insulation treatment of the vent pipe of the gas distribution station, and the different environment of the gas transmission pipeline, so as to take different protection measures.

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.
