The PP-R Diamond Blue composite pipe series uses food-grade Nordic chemical PP-R pure raw materials. It effectively solves the problem of scale and impurities adhering to the pipe wall with a large water flow. It can ensure water safety throughout the entire service life of the pipe and prevent scale and impurities from adhering and accumulating inside the pipe, truly achieving the dual function of self-cleaning water and preventing mold.
The PP-R Diamond Blue Composite Pipe is designed with a multi-layer reinforced structure to improve durability, hygiene, and long-term performance in water supply systems. Each layer is engineered to enhance protection, strength, and flow efficiency.
The outer blue shield layer protects the PP-R Diamond Blue Composite Pipe from ultraviolet radiation, preventing aging and embrittlement. It also improves pressure resistance and impact resistance, ensuring stable performance in long-term installation environments.
The middle reinforcing layer is made of precision fiber composite material, providing high strength, rigidity, and excellent temperature resistance. It also enhances bending resistance, allowing the pipe to maintain structural stability under complex installation conditions.
The inner Shunshui cleaning layer uses a patented high-flow design to reduce scale and impurity adhesion on the pipe wall. This ensures smooth water flow, improves hygiene performance, and enhances overall system efficiency.
The PP-R Diamond Blue Composite Pipe uses European standard CW617N brass components, manufactured through high-precision stamping and forming processes. The structure and thickness of the copper inserts are reinforced to ensure a seamless connection with PP-R materials.
The refined CW617N copper insert is nickel-free, preventing heavy metal leaching. Its dense structure provides high tensile strength and crack resistance, ensuring safe and stable long-term use in water systems.
The integrated pressure ring is designed for water-locking and sealing performance. It offers anti-fraying, waterproof, and hammer-resistant properties, ensuring reliable sealing under pressure conditions.
The wide rib reinforcement and waterproof dovetail groove structure improve anti-twisting performance. This ensures a strong bonding between copper and plastic components, effectively preventing leakage and enhancing system stability.
The pipe is made from high-quality polypropylene materials sourced from Borealis. It is non-toxic, odorless, and free from recycled materials, ensuring safety, hygiene, and environmental friendliness without harmful leaching.
The central layer adopts a high-polymer toughening formula, improving explosion resistance and crack resistance. This ensures long-term stability and safe operation of the pipeline system.
Designed with S2.5 pressure rating, the PP-R Diamond Blue Composite Pipe supports high-pressure applications. Precision heat fusion welding ensures strong material integration between pipes and fittings, effectively eliminating leakage risks.
