Green environment-protection aluminum-plastic pipe

aluminum plastic pipe Professional Design and Advanced Technology we can do best for your needSpec Intine thickness Spec Intine thickness Spec Intine thickness PN= 1.25 Mpa 20 2.3 PN= 1.25 Mpa 20 2.8 PN= 1.25 Mpa 20 3.4 25 2.8 25 3.5 25 4.2 32 3.6 32 4.4 32 5.4 40 4.5 40 5.5 40 6.7 50 5.6 50 6.9 50 8.4 63 7.1 63 8.7 63 10.5 75 8.4 75 10.3 75 12.3 90 10.1 90 12.3 90 15.0 110 12.1 110 15.1 110 18.3 Features: 1.The expansion coefficient is only 20 to 30% of oridinary PP-R pipes;It provides a thorough solution to the expansion problem of plastic pipes. 2.Strengthened pipe rigidity can prevent the pipelinefrom sagging but also has reduced the density and the number of fixed support points,thus reducing the total cost of the project. 3.With its better high temperature performance,it can obviously reduce energy consumption;In hot-water system,FR-PPR pipe's normal working temperature can be 95 100°C.It has not only improves the applicable medium temperature, and can decrease the thickness of insulating material, its comprehensive cost less. 4.With higher voltage level,it has a longer service life under the normal design tremor force. 5.Big water flow:smooth wall and small system pressure loss. 6.It has solved the problem of pipeline's oxygen permeability.The inside surface directly contacting water is non-toxic,of good tightness and without forming sphagnum.The middle layer composition of GF FR-PPR pipes can entirely keep the outside air from infiltration inside the pipe,thus inhibiting the growth of algae and maintaining the purity of fresh water.
