PP-R environmental protection and health water supply pipe series products are meticulously crafted in adherence to the highest standards and stringent requirements of the ISO9001 quality system, ensuring unparalleled quality and durability.
The PP-R drinking water pipe is a cutting-edge product widely adopted in the most developed nations globally. Utilizing advanced homogeneous welding technology for both cold and hot water transportation projects, it boasts superior technical performance and economic efficiency compared to other similar products. Its exemplary hygienic properties meet the highest standards for health and environmental protection, from production through use, to disposal and recycling.
This product offers remarkable advantages including heat resistance, pressure endurance, thermal insulation, energy efficiency, longevity, and cost-effectiveness. It is on track to replace existing water pipes and become the market leader. Traditional metal pipes react chemically with various substances, minerals, and impurities in water, leading to oxidation, degradation, and secondary pollution. In contrast, PP-R pipes are made from recycled and reusable environmentally-friendly materials that reinforce polypropylene. These pipes do not release heavy metals or harmful substances, do not scale, and comply with stringent sanitary and health standards. Therefore, PP-R pipes are the ideal sanitary and eco-friendly solution for transporting drinking water and for use in the food industry.

Features
★ Hygienic, Non-Chemical, and Eco-Friendly: Crafted from polyolefin, a green building material composed solely of carbon and hydrogen elements, ensuring reliable and superior hygienic performance.
★ Convenient and Reliable Installation: Utilizing homogeneous hot-melt connection, our pipe systems allow for rapid, secure joint connections, saving both time and effort.
★ Heat Preservation and Energy Efficient: With a thermal conductivity of just 0.24W/m.k, our pipes significantly reduce heat loss, making them ideal for hot water systems.
★ Lightweight with High Specific Strength: Our pipes weigh merely one-eighth of steel pipes and boast high pressure test strength, excellent toughness, and remarkable impact resistance.
★ Smooth Inner and Outer Walls: Designed with minimal flow resistance to ensure energy-efficient fluid conveyance within your systems.
★ High Heat Resistance: Capable of withstanding long-term operating temperatures of 70ºC and short-term peaks up to 95ºC, perfect for a range of hot water applications.
★ Corrosion-Resistant and Non-Scaling: Prevents fouling and clogging, eliminating yellow spot rust in water basins and bathtubs.
★ Exceptionally Long Service Life: Engineered for durability, our pipes offer a normal service life exceeding 50 years.
Product Application Range
★ Ideal for Hot and Cold Water Pipe Systems.
★ Perfect for Heating Systems, including floor, wall, and radiant heating configurations.
★ Suitable for Pure Water Piping Systems.
★ Compatible with Central (Centralized) Air Conditioning Systems.
Pipe Connection
★ Mark the socket depth at the pipe insertion end after piping.
★ Clean the connecting end faces of pipes and fittings. Thread the pipe into the pipe joint cover for a secure fit.
★ Use a hot melt machine to heat the pipes and fittings. Ensure heating parameters meet the technical requirements of the specific hot melt machine being used.
★ Upon reaching the desired heating time, swiftly remove and join the pipe and fittings without rotation to the marked depth, ensuring a uniform flange at the joint.
★ Apply the pipe joint cover post-welding for added security.
★ Achieve a flawless match as pipes and fittings completely melt into a unified structure.
