[0002] Liner pipe molding and curing is a manufacturing technology that is usually used to manufacture products such as pipes, tanks, and containers. The basic principle of this technology is to coat a special lining material (such as rubber, plastic, composite material, etc.) on the inner wall of a metal or concrete pipe, and then cure the lining material by heating, pressurizing or chemical reaction, thereby forming a strong, corrosion-resistant and smooth lining layer.

Due to the limitations of manual operation, the inner wall of the liner pipe is unevenly coated. The uneven coating causes the coating in some areas to be thinner and defective, exposing the surface of the liner pipe to the corrosive environment, thereby reducing the corrosion resistance. Therefore, the present application proposes a polytetrafluoroethylene liner pipe molding and curing device. Summary of the invention
