Pex-al-ppr pipe

Features:

1) Hygienic and nonpoisonous: completely green building materials, can be used for

    pure water and drinking water pipeline systems

2) Because it has inserted the aluminum layer in middle, linear coefficient of expansion

    is little, and has intensity equal to that of metal pipe. Toughness is good,

    with shock-resistant property

3) Corrosion-resistant and forming the dirt. Can avoid pipeline and forming from

    stopping

4) Can bear high temperature and pressure. Under fixed long-term working pressure,

    the pipeline delivery temperature can be up to 95^oC

5) Keep energy-conservation warm: heat conduction coefficient metal, 1/200 of

    pipeline only, used for hot water pipeline, keep energy-conservation warm excellent

6) Proportion is only 1/7 of the metal pipeline

7) Beautiful appearance: the internal and external walls are smooth, fluid obstruction

    is small, and color and luster are soft

8) Can be buried underground: can survey out the position of tube with metal

    detector

9) Convenient and reliable to install: can finish first piercing joint in 1s, water

     dividing device adopts high quality copper inlay pieces, which give safe and reliable

     performance with metal pipes

10) With long using life: more than 50 years normally

triplex layer: outer layer and inner layer is made from pex and pp-r materials ; middle layer is made from AL
