As a new pipe,Plastic-aluminum composite pipe selected welded process and methods of using physical complex chemical compound. In a high-temperature molten polyethylene, aluminum tubes in a heated state, between the aluminum and polyethylene, then add a layer of sticky hardens, forming polyethylene, adhesive, aluminum, adhesive, polyethylene five-layer structure.

      Five material by high temperature, high pressure fused into one to form this new type of composite pipe, which fully reflects the respective advantages of metal and plastic materials, and to make up for their deficiencies.Aluminous model multiple tube anti aging performance is good, ductile-brittle bottom temperature, uv protection, under the condition of no heat and strong ultraviolet radiation, the service life of over 50 years.

      Its applicability is wide and can be used with water and hot water pipe agriculture and gardening tube, heating tube, industrial pipe, hot spring tube, the sun can pipe, utilities, etc., in the engineering construction convenient and quick, shorten the time limit for a project, bright colors, beautiful generous, is the ideal substitute galvanized pipe.
