It's composited by the standard PP-R pipe and alloy aluminum with hot melt adhesive technology, and its outside is coated with PP-R protective layer. It has the advantages of plastic pipe and metal pipe, including health and sealing of plastic pipe, ultraviolet-proof, no oxygen permeability or open installation deformation of metal pipe, its linear expansion coefficient is 1/5 of the normal PP-R pipe, close to the metal pipe, has the higher strength and more stable function. It's suitable for the heating pipeline system of hot and cold water supply, central air conditioning and radiator, is a high-quality composite pipe of the new generation.
1, More beautiful appearance, small expansion coefficient, without deformation in open installation.
The expansion coefficient PP-R aluminum-plastic pipe is small, close to the metal pipe, suitable for open installation of indoor or outdoor, beautiful appearance, no deformation; compared with the ordinary plastic pipe, its supporting interval can be increased to reduce the use of the pipe clamp holder; only cover thin cement layer in covered installation to save work materials.
2, Healthier, no oxygen permeability, prevent algae growth.
We cover high strength aluminum alloy on the outside of PP-R aluminum-plastic pipe to completely isolates from the outside air, into, prevent the oxygen from infiltrating into water, so as to inhibit the algae growth, maintain clean and healthy water quality; At the same time, prevent the metal parts of heating and air conditioning system from appearing oxidation and corrosion to ensure the safe, stable and efficient system operation.
3, Longer service life, resistance to UV, prevent the material oxidation.
Its aluminum layer can effectively block UV, provides the UV protection barrier for pipe. Pipe can be used for hot and cold water outdoor installation without deformation, discoloration and aging, service life is longer, it's the ideal choice for solar energy, outdoor pipe network system.
