Our PP-R environmental protection and health water supply pipe series products are meticulously crafted in line with the highest standards and stringent requirements set by the ISO9001 quality system.
The PP-R drinking water pipe represents the pinnacle of innovation, widely adopted in developed nations across the globe. Utilizing advanced homogeneous welding technology, it excels in both cold and hot water transportation projects. This cutting-edge product showcases superior technical performance and economic indicators, far outpacing other similar offerings. Its exceptional hygienic properties ensure it meets the most rigorous hygiene and environmental protection standards, from production through to disposal and recycling.
Our PP-R pipes are engineered with remarkable attributes including heat resistance, pressure tolerance, thermal insulation, energy efficiency, and an exceptionally long service life. These pipes are poised to gradually replace traditional water pipes, emerging as the industry-leading solution. Water often contains various chemicals, minerals, and impurities that, when in contact with metal pipes, can cause oxidation, flaking, and secondary pollution. In stark contrast, our recyclable and reusable PP-R pipes are made from an environmentally friendly, reinforced polypropylene material that is free from heavy metals and other harmful substances. The non-scaling pipe walls meet stringent sanitary and health standards, making PP-R pipes the ideal choice for sanitary and eco-friendly water and food industry transportation.

Features
★ Hygienic, non-chemical, and eco-friendly: Crafted from polyolefin, our PP-R material is comprised solely of carbon and hydrogen, ensuring reliable hygienic performance.
★ Convenient and reliable installation: Utilizing homogeneous hot-melt connections, joint connections are completed swiftly, making the installation process both quick and time-saving.
★ Heat preservation and energy efficiency: With a thermal conductivity of just 0.24W/m.k, our fittings exhibit twenty times less heat loss compared to metal pipes, making them ideal for hot water pipes.
★ Lightweight with high specific strength: Our fittings weigh roughly one-eighth that of steel pipes, offering high pressure test strength, excellent toughness, and strong impact resistance.
★ Smooth inner and outer walls: The minimal flow resistance ensures lower energy consumption for fluid conveyance systems.
★ Superior heat resistance: Designed for long-term use at 70ºC and capable of withstanding temperatures up to 95ºC for short durations.
★ Corrosion-resistant and non-scaling: Helps prevent fouling and clogging in pipes, as well as rust stains in water fixtures.
★ Extended service life: Engineered to last over 50 years under normal conditions.
Product Application Range
★ Suitable for both hot and cold water pipe systems.
★ Ideal for heating systems, including floor, wall, and radiant heating solutions.
★ Perfect for pure water piping systems.
★ Compatible with central (centralized) air conditioning systems.
Pipe Connection
★ Post-piping, mark the socket depth at the pipe insertion end.
★ Clean the connecting end faces of pipes and fittings, then thread the pipe into the pipe joint cover.
★ Heat the pipes and fittings using a hot melt machine, ensuring the heating parameters align with the technical specifications of the machine.
★ Once the heating time is reached, remove the pipe and fittings simultaneously and insert them in a straight line to the marked depth without rotation, forming a uniform flange at the joint.
★ After welding, secure the pipe joint cover.
★ The pipes and fittings fuse completely, achieving a seamless and perfect match.
