  •    Aluminum PP-R pipe series

        Aluminum-plastic PP-R composite pipe comprises of five-layer mutual-extruded structure, interior layer is food degree PEX(PE),exterior layout is o PP-R; middle one is of longitudinal superposition-welded aluminum layer which isolates each kind of liquid from penetration. It integrates in excellent high-temperature resistant performance for aluminum-plastic composite pipe and less distortion after heated while having reliability for PP-R tubing thermal melting connection. So it preferably settles down shortcoming of higher cost for aluminum-plastic composite tube joint and more linear expandability coefficient for PP-R tubing, its connection is the same as that of PP-R tubing.
    >Resistance to high temperature and high pressure
    >Resistance to erosion and the noiseless water hammer
    >Smooth inwall guaranteeing the least resisting force and the largest amount of water
    >The longevity of over 50 years
    >Clean and hygienic and oxygen-proof
    >Resistance to electrostatic and high ignition point
    >Resistance to frost and earthquake-proof
    >Flexural and no resilience
    >Easily transferred and stored
    >Few joints and lower leakage rate
    >Easily installed yet applicable for numerous fields
