The production process of aluminum-plastic composite pipe: first make the lap-welded longitudinal aluminum pipe, and then make the inner and outer layers of plastic pipes on the formed aluminum pipe, which is called the lap joint production process; first make the inner layer of plastic pipes, and then The aluminum tube with butt welding on it is finally covered with a plastic layer on the outside, which is called the butt welding production process. The main advantages of aluminum-plastic composite pipes: Most of the water pipes used galvanized pipes, aluminum-plastic pipes, copper pipes and other materials for waterway connections. However, these materials have the following disadvantages in construction: some galvanized pipes have Trachoma, the inner wall is easy to rust, the construction is more complicated, and the difficulty factor is higher; generally, aluminum-plastic composite pipes are used to replace traditional pipes, which have both the pressure resistance of metal pipes and the resistance of plastic pipes. The main advantages of the aluminum-plastic composite pipe are: it has the same strength as the metal pipe, it is easy to bend and does not rebound; it has excellent high temperature resistance, high pressure resistance and corrosion resistance; the inside of the pipe is smooth, the resistance is small, and it is not easy to block; good flame retardancy, heat insulation Good thermal insulation performance; due to the use of aluminum core, it can completely isolate oxygen, inhibit bacterial reproduction, light weight, convenient processing, and its service life can reach more than long-term durability according to standards.
