Glass fiber reinforced composite PPR pipes PPR-FB-PPR Jiuhao fiberglass reinforced composite PPR pipe is five-layer composite pipe that combines the advantages of a metal and plastic pipe and eliminates the disadvantages of both materials at the same time. As shown in the picture, Jiuhao fiber glass pipe has multilayers: interlayer is enhanced glass fiber material, inner layer hot water material Outer layer: imported ppr material. Jiuhao fiberglass PP-R pipes have higher temperature resistance, low expansion ratio—20% of ordinary PP-R pipes. Features: 1. Higher pressure resistance 2. Long using life, high-strenghth, anti-shock. 3. Prevent sagging situation. 4. sanitation, do not rust, rot, or corrode. Application: Idealy for solar energy, thermal enger circulation system, heating and water supply.
