What are the main characteristics of aluminum alloy lined pert composite pipe?

The outer aluminum tube of the aluminum alloy lined plastic composite tube is 6063 deformed aluminum, and the inner tube is thermoplastic PPR pert, Pb three kinds of plastic tubes. Double-layer structure composite pipe composed of prestressed composite-aluminum alloy lined composite pipe.

1. Surface treatment technology: The aluminum alloy lined plastic (PPR pert Pb) composite pipe product not only matches the color of the pipe surface with the color of the aluminum alloy outer pipe (PPR pert Pb), the plastic pipe itself also has UV protection (655)

2. The physical prestressing technology used in the aluminum alloy plastic-lined (PPR pert Pb) composite pipe, through the prestressing composite technology, effectively combines two materials with different elongation (aluminum alloy metal pipe) and thermoplastic pipe), the composite pipe formed by prestressing composite of the two materials is designed with reasonable parameters on the joint surface of the two materials, and a good joint strength between layers is obtained. Make the entire composite tube play a consistent role in cold axis, thermal expansion.

3. The linear expansion coefficient of the aluminum alloy lined composite pipe is only about one-fifth of that of the pure plastic pipe. In terms of stiffness and strength, the performance of aluminum alloy lined composite pipe is better than that of single material (aluminum pipe or plastic pipe).

Aluminum alloy lined ppr pipe is a composite pipe, aluminum alloy lined plastic pipe, the outer layer is 6063 seamless aluminum alloy layer, the inner layer is PERT, PPR, PB pipes that meet national standards, and the outer aluminum alloy layer is oxidized to form trioxide. The aluminum oxide film will not be damaged due to long-term contact with air and other media, which ensures the service life of the aluminum alloy lined plastic pipe for more than 50 years.

The aluminum alloy plastic-lined composite pipe has the advantages of PERT plastic pipe hygiene, corrosion resistance, low thermal conductivity, and good conveying performance; at the same time, due to the external aluminum alloy protective layer, it overcomes the low surface hardness, poor rigidity, and linear expansion coefficient of the plastic pipe. The disadvantages of large size, poor UV resistance and easy aging make the aluminum alloy plastic-lined PERT pipe grafted with the aluminum alloy metal pipe to have the advantages of high hardness, good strength, impact resistance, and gorgeous appearance.
