    PPR Pipes (Polypropylene Random)- among plastic pipes, the PPR pipe is the most popular one in plumbing across the world owing to its well-established technical, economic and ecological advantages. There are various chemicals, minerals and impurities that can react with the wall of metal pipe and produce oxidation or exfoliation, resulting in the second pollution. PP-R pipe uses reinforced polypropylene, a recyclable and environmentally-friendly material, which can prevent the release of heavy metals and other harmful substances. Compared to other kinds of pipes, DUNHUA PP-R pipes boast itself the higher temperature resistance, stress cracking resistance, economic efficiency and a longer service life with the quality up to the standard of DIN8077/8078 of Germany.

  • The Advantages of DUNHUA PP-R Pipes:
    Long-term service life of over 50 years under regular operating conditions.
    Light weight and high strength: 1/8 weight of metal pipes; good ductility & impact resistance and high-class stress cracking resistance
    High thermal insulating: The water temperature transmitted up to 70℃ and maximum up to 95℃
    Good heat insulating and energy saving: The coefficient of heat conductivity is only 0.5% (1/200) over that of the metal pipes, which is good for hot water piping applications.
    Excellent corrosion resistance: Unaffected by electrolytic or galvanic corrosion or any known corrosive soil or water conditions.
    High flow capacity: Smooth interior over long years of service without carrying capacity loss.
    Outstanding installation safety: Hot-fusion junctions are adopted, which is finished in just several seconds. 
    Excellent chemical stability & environmental friendliness
