Crafted to perfection, our PP-R environmental protection and health water supply pipe series is an embodiment of excellence, strictly adhering to the high standards of the ISO9001 quality system. Experience unrivaled quality, where each pipe is a testament to meticulous production processes and stringent requirements.
Embrace the future with our PP-R drinking water pipe—an innovative marvel extensively used in developed nations. It harnesses the power of homogeneous welding technology for flawless performance in both cold and hot water distribution. The technical superiority and cost-efficiency of this pipe are unmatched, elevating it above its peers. Its exemplary hygienic properties satisfy the most stringent health and environmental criteria throughout its lifecycle, from production to disposal and recycling.
Our product stands as a paragon of durability with its heat and pressure resistance, thermal insulation, and energy conservation benefits, promising a long and economical service life. It is poised to outshine and replace existing alternatives, claiming its place as a leading solution. When water, laden with chemicals, minerals, and impurities, flows through metal pipes, it results in chemical interactions that oxidize and degrade the pipe walls, leading to contamination. In contrast, our PP-R pipes, crafted from recyclable materials, fortify polypropylene without releasing harmful heavy metals or substances, ensuring a pristine and safe water supply. Its smooth interior prevents scaling, aligning with rigorous sanitary and health standards. Undoubtedly, the PP-R pipe is the ideal choice for safe, hygienic, and environmentally-conscious water and food industry transport.

Features
★ Experience unparalleled hygiene with our non-chemical, eco-friendly green building material. Crafted from PP-R polyolefin, this material boasts a molecular structure of pure carbon and hydrogen, ensuring supreme reliability in hygiene performance.
★ Enjoy the ease and dependability of installation with our homogeneous hot-melt connection, enabling rapid and efficient joint connections. This saves both time and effort, making your installation process seamless.
★ Benefit from remarkable heat preservation and energy efficiency, with a thermal conductivity of just 0.24W/m.k. This is a mere fraction—one-twentieth—of traditional metal pipes, making it ideal for hot water systems and minimizing heat loss.
★ Our pipes boast a lightweight design with high specific strength, being just one-eighth the weight of steel pipes. They offer impressive high-pressure test strength, excellent toughness, and outstanding impact resistance.
★ Featuring smooth inner and outer walls, our pipes reduce flow resistance significantly, resulting in lower energy consumption within your fluid conveying system.
★ Experience high heat resistance with our pipes, sustaining a working temperature of 70ºC for prolonged use, and capable of withstanding up to 95ºC for short durations.
★ Enjoy corrosion resistance and non-scaling properties, effectively preventing fouling and clogging in pipes, and eliminating unsightly yellow rust spots in water basins and bathtubs.
★ Our pipes promise durability with a remarkable service life that extends beyond 50 years under normal conditions.
Product application range
★ Ideal for both hot and cold water pipe systems.
★ Perfect for heating systems, including innovative floor, wall, and radiant heating solutions.
★ Exceptional for pure water piping systems, ensuring purity in every drop.
★ Suitable for central (centralized) air conditioning systems, ensuring reliable performance.
Pipe connection
★ For precise fitting, mark the socket depth at the pipe insertion end before proceeding.
★ Clean the connecting end faces of both pipes and fittings meticulously. Thread the pipe seamlessly into the pipe joint cover for a secure fit.
★ Utilize a hot melt machine expertly to heat the pipes and fittings intended for connection. Ensure that heating parameters comply with the technical specifications of your chosen hot melt machine.
★ Upon reaching the optimal heating time, swiftly remove and align the pipe and fittings without rotation, inserting them evenly to the marked depth to form a uniform flange at the joint.
★ Secure the connection by placing the pipe joint cover after welding, ensuring durability and stability.
★ Achieve a flawless union as pipes and fittings seamlessly melt into one cohesive unit, showcasing a truly perfect match.
