Abstract: Heat supply network is an important infrastructure for urban central heating, which has a significant meaning in ensuring residential heating. With the development of long-distance heating transmission and the increase of heating temperature, the materials in the heating pipeline network are facing more severe corrosion environment. The accidents in the heating pipeline network caused by corrosion failure have accounted for more than 90%. Hence, we must pay more attention to them. Combined with the research work of heating pipe network at home and abroad and the field engineering experience, this paper summarizes the corrosion problems faced by heating pipe network, summarizes the existing corrosion control methods, and prospects the research route of corrosion prevention of heating pipe network. This paper can provide a reference and basis for the study of corrosion of heating pipe network materials, and also provide a new idea for the study of corrosion control methods of this system.
