32mm Grey ppr-al-ppr pipe  

PPR-AL-PPR Pipes

PPR-AL-PPR composite pipe is composite pipe of five layers, inside and outside layers of which are made of PP-R, tightly bonded with mel adhesive to the mid-layer of aluminum core which is longitudinally welded in a butt welded or overlap-welded way, this kind of pipe is the perfect union of metal and the plastic ones.

Advantages

*Compared with the ppr plastic pipe, the ppr composite pipe has the same strength, reluctant to retain former shapes

*Smooth inner surface of the pipe reduces resistance to the fluids. The ability to conduct water is 30% more efficient

*Super properties of high temperature, high pressure and corrosion resistance

*Good property of heat preservation, heat conduction coefficient is 0.45 W/m.k, which is much less than metal pipes and it can save insulation materials outside the pipe

*Easy to cut and install. It can be connected with special fittings instead of screw fittings; small diameter pipes can be rolled and packaged. Once bent in order than many directional parts such as elbow s or angles are no longer recessing very convenient to install, much time and labor cost can be saved

 *Life pan of the composite pipe is more than 50 years
