PPR-AL-PEX pipe imports the latest composite pipe technical from Germany. The pipe adds an aluminum alloy on the base of PP-R pipe, using macromolecule cement under a high temperature compound the PP-R pipe and aluminum. This pipe is the perfect union of metal and plastic pipe but has the hygienic, hermetic of plastic pipe, the rigidity of metal pipe, a much higher intensity, much more stable mechanical property at the same time. It also can prevent ultraviolet, the linear expansion ratio is 1/5 of the normal PP-R pipe which is close to the metal pipe, it possess much higher stability and safety.
1.Low linear expansion ratio: the linear expansion ratio of PPR-AL-PEX is lower than 1/4 of PP-R pipe, which is close to metal material, there is superiority when used in hot water, warm thrown and outside installment.

2.Superiority oxygen proof: because the middle layer is aluminum. it completely resist the outside air. it makes sure that the water in the pipe will not mixed with oxygen. When used in center air-conditions and heating system it can prevent the metal part's oxidation and corrosion .no oxygen no bacilli. So it makes the pipe sanitation.

3. Safety trustiness and speediness connection mode: this pipe uses PPR fitting for connecting, just a welding machine will be OK, and it goes to be economical.
