Smooth inner and outer walls ensure small fluid resistance. The pipes are beautiful in shape and weigh only 1/8 of metal tubes, facilitating easy transportation and installation.
High pressure and temperature resistance allow for a service life of up to 50 years under normal conditions.
Green building materials that are non-toxic, non-polluting, and recyclable. Suitable for both hot/cold water and potable water systems.
With a Vicat softening point of 131.5ºC, it can operate long-term at 70ºC, meeting hot water system requirements in modern buildings.
Thermal Conductivity is only 0.21w/m.k, which is just 1/200th that of steel pipes.
Hot-melt connections create a molecular-level fusion between pipes and fittings in seconds, creating a perfectly integrated system.
PPR water pipes undergo rigorous inspection from raw materials to finished products, including MTR, Hardness, Hydrostatic pressure, and burst pressure testing.
