Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation metal pipes, in particular to a protective anti-corrosion thermal insulation metal pipe. Background Art

[0002] With the continuous increase in the depth of coal mine mining, geothermal phenomena in major coal mines across the country are becoming increasingly serious, especially the geothermal disaster problem of Huainan Mining Group is particularly prominent, and the temperature in some areas can reach 43°C. At present, the main measures to solve the high temperature problem of underground working faces in coal mines are to increase the air convection speed to cool down or reduce the heat dissipation of electromechanical equipment in the mine, and reduce the mining time of miners, but none of them can effectively solve the problem of heat damage. At present, the non-refrigeration air conditioning cooling measures in mines can no longer meet the working environment requirements of the working face, and it is imperative to take air conditioning cooling measures. However, the special environment of underground coal mines cannot use ordinary fluorine refrigeration and air conditioning, and water refrigeration must be used. The cold water of the refrigeration and air conditioning is transported from the ground to the mine working face. The pipeline can reach 2 to 3km. At present, the air conditioning and refrigeration pipelines in mines mainly use polyurethane insulation pipes, and their flame retardancy and antistatic have not been well solved; they are mainly insulated by filling foam plastics. Because they are filled manually and wrapped with foam plastics, the filling layer and foam layer are very thick, and it is easy to fill and wrap unevenly, the insulation effect is poor, and the construction and installation are also inconvenient;
