Discuss the factors affecting the corrosion rate of buried steel pipes

Thread Content

　　The main factors affecting the corrosion rate of pipes are the intensity of the corrosion current and the corrosion time. Therefore, to take appropriate anti-corrosion measures, we can only control its current intensity and corrosion time in order to effectively minimize the amount of metal loss in the pipes, thus ensuring that the quality of the pipes is not affected. 　　In electrolytes, the main factors affecting the intensity of corrosion current include the resistance present in the soil, the chemical structure of the soil electrolyte, and the distance between the cathode and the anode; all these factors directly influence the intensity of corrosion current in the soil. The lower the resistance present in the soil, the greater the intensity of the corrosion current. The resistance of the soil is related to its temperature, humidity, as well as the concentration of salts it contains; therefore, when trying to control the intensity of the corrosion current, it is necessary to manage these factors such as soil temperature, humidity, and salt content in order to minimize the impact on gas pipelines.
