The aluminum plastic pipe is a new type of pipeline which is made up of intermediate longitudinal welded aluminum tube, inner and outer polyethylene plastic and the hot melt adhesive between the layer and the layer. Aluminum plastic pipe (aluminum plastic composite pipe) is lightweight, durable and easy to construct, and it is more suitable for home decoration. The inner and outer layers of aluminum plastic pipes are made of special polyethylene, clean, non-toxic and smooth. It can be used for more than fifty years. Use: 1. Cold and hot water piping system: Used for cold and hot water pipe system in industrial and civil buildings. 2. Indoor gas piping system: Used for compressed air, gas, oxygen and other gas transmission line is safe and reliable. 3, Solar air conditioning piping system It is not easy to frosting and has good thermal insulation and improves the efficiency of solar energy and air conditioning systems. Advantage: 1. Outstanding health performance: The middle aluminum layer of the aluminum plastic pipe eliminates the growth of microbes and algae. 2, High and low temperature performance is excellent:Long service temperature 95 degrees, maximum use temperature 110 degrees, and aluminum plastic tube thermal expansion coefficient is small. 3. Long service life and strong aging resistance.
