Our PP-R environmental protection and health water supply pipe series are meticulously crafted to align with the rigorous standards of the ISO9001 quality system, ensuring unparalleled quality and reliability.
Revolutionizing the world of water transportation, our PP-R drinking water pipes epitomize cutting-edge technology and advanced engineering. Widely adopted in developed nations, these pipes employ homogeneous welding technology for both cold and hot water projects. Their superior technical performance and economic viability outshine other conventional products. Notably, their exceptional hygienic properties adhere to the highest standards of environmental protection, from production through disposal and recycling.
Boasting remarkable attributes such as heat resistance, pressure endurance, and thermal insulation, our product promises significant energy savings and longevity. It stands poised to supplant traditional water pipes, emerging as the industry's flagship solution. Water, laden with diverse chemicals, minerals, and impurities, often induces chemical reactions upon contact with metal pipe walls, leading to oxidation, degradation, and secondary pollution. In contrast, our PP-R pipes, composed of eco-friendly, reinforced polypropylene, are devoid of heavy metals and harmful substances. They resist scaling, ensuring compliance with stringent health and sanitary regulations. Ideal for drinking water and food industry applications, PP-R pipes are the epitome of sanitary and environmentally responsible water conveyance solutions.

Features
★ Hygienic and eco-friendly: Made entirely of polyolefin, which contains only carbon and hydrogen molecules, Smart PPR Fittings are non-chemical and green building materials, ensuring reliable hygienic performance.
★ Convenient and reliable installation: With homogeneous hot-melt connections, joints can be completed quickly, saving both time and effort during installation.
★ Heat preservation and energy-saving: With a thermal conductivity of just 0.24W/m.k, which is only one-twentieth that of metal pipes, these fittings ensure minimal heat loss for hot water applications.
★ Lightweight and robust: Being approximately one-eighth the weight of steel pipes, these fittings offer high-pressure strength, excellent toughness, and superior impact resistance.
★ Optimized flow: The smooth inner and outer walls reduce flow resistance, thus leading to lower energy consumption in fluid transport systems.
★ High heat resistance: Ideal for long-term water conveyance at 70ºC, these fittings can also withstand short-term use at temperatures up to 95ºC.
★ Corrosion-resistant and non-scaling: These fittings prevent fouling, clogging, and the yellow rust spots often found in water basins and bathtubs.
★ Longevity: Designed to last, Smart PPR Fittings boast a service life exceeding 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 applications.
★ Perfect for pure water piping systems.
★ Compatible with central and centralized air conditioning systems.
Pipe connection
★ Mark the socket depth on the pipe's insertion end after piping.
★ Clean the connecting faces of the pipes and fittings, and thread the pipe into the pipe joint cover.
★ Utilize a hot melt machine to heat the pipes and fittings. Ensure the heating parameters align with the technical specifications of the hot melt machine.
★ Upon reaching the heating time, simultaneously remove the pipe and fittings, and insert straight without rotation to the marked depth until a uniform flange forms at the joint.
★ Place the pipe joint cover after welding.
★ Achieve a flawless match as the pipes and fittings melt into a single, unified structure.
