Product Introduction:

Our premium home installation PP-R water supply pipes are manufactured in strict compliance with the ISO 9001 quality management system, meeting the high standards of GB/T 18742.1, GB/T 18742.2, GB/T 18742.3, and the GB/T 17219 hygiene standards, as well as the health and safety evaluation regulations set by the National Health Department. PP-R pipes are widely adopted in developed countries as a next-generation piping solution.

Utilizing homogeneous fusion welding technology for both cold and hot water distribution systems, they offer superior technical performance and cost-efficiency compared to traditional piping materials. Their exceptional hygienic properties ensure compliance with the highest health and environmental standards—from production and usage to disposal and recycling.

Product Features:

1. Hygienic & Chemically Inert – Green Building Material: PP-R (Polypropylene Random Copolymer) is an olefin-based material composed solely of carbon and hydrogen, ensuring reliable sanitary performance.
2. Easy & Reliable Installation: Homogeneous heat-fusion joints enable quick, secure connections, significantly reducing installation time.
3. Thermal Insulation & Energy Efficiency: Low thermal conductivity (0.24 W/m·K), just 1/200th of metal pipes, minimizes heat loss in hot-water systems.
4. Lightweight & High Specific Strength: Density ≈ 1/8th of steel pipes; excels in pressure resistance, toughness, and impact performance.
5. Smooth Interior/Exterior Walls – Low Flow Resistance: Reduced hydraulic friction lowers pumping energy consumption in fluid systems.
6. High Heat Resistance: Continuous service: 70°C; short-term tolerance: 95°C.
7. Corrosion & Scale Resistant: Eliminates pipe clogging and prevents rust stains in sinks/bathtubs.
8. Long Service Life: 50+ years under normal operating conditions.

Product Applications:

1. Cold and hot water pipeline systems within buildings, including central heating systems.
2. Building heating systems, including floor, wall panel heating, and radiant heating systems.
3. Direct drinking pure water supply systems.
4. Central (centralized) air conditioning systems.
