The current implementation of the Yellow River water source Taiyuan urban water supply project is to lay a water supply network within the city. The pipe diameter of the pipeline is DN300mm-DN2220mm, and the total length is 163km. The large-diameter pipelines are all made of steel pipes. In order to ensure the quality of the project, the life of the steel pipe is prolonged. The corrosion protection of the inner and outer walls of the steel pipe is extremely important. There are many factors in the corrosion of underground pipelines, such as the soil pH value in the pipeline area, and the grass roots will penetrate the general coating. The inner wall of the water supply pipe is made of cement mortar, and the outer wall is made of epoxy coal tar pitch paint. After years of engineering practice, it proves to be a kind of non-corrosion.
