PPR Pipe (Random Copolymer Polypropylene)is a third-generation specialized material for polypropylene piping, also known as Type 3 Polypropylene. PPR Plastic Pipe overcome the drawbacks of homopolymer polypropylene, offering excellent impact resistance while maintaining long-term thermal stability. Plastic PPR Water Pipe also ensure a longer service life under the same temperature and internal pressure conditions.

Characteristics
PP-R pipes not only possess the general advantages of plastic pipes, such as lightweight, high strength, corrosion resistance, scale-free properties, and long service life, but also feature the following main characteristics:
1.Eco-friendly building material: PP-R raw material belongs to the polyolefin family, with molecules composed of carbon and hydrogen elements, ensuring reliable hygienic performance.
2. Heat-resistant and insulating, making it an energy-saving product.
3. Easy and reliable installation: Homogeneous hot-melt connections can be completed in seconds, while high-quality metal-embedded fittings are used for connections with metal pipes and water appliances, ensuring safety and reliability.
Applications
1.Cold and hot water pipeline systems in buildings, including central heating systems.
2. Heating systems in buildings, including underfloor, wall panel heating, and radiant heating systems.
3. Direct-drinking pure water supply systems.
4. Central (centralized) air-conditioning systems.
