FRP pipe FRP winding pipes GRP pipe FRP cable pipe ◎ good corrosion resistance, long life glass pipes can withstand a variety of long-term erosion of acid, alkali, salt, organic solvents and water, sewage and other chemical mediators. Can be selected depending on the different properties of the pipe and the temperature of the medium type. ◎ excellent mechanical properties of the glass pipe a small proportion (1.8 ~ 2.1g / cm 3) high intensity (≥300MPa), which is much larger than the specific strength steel pipes and cast iron pipe, since the wall of the intermediate layer added to the resin mortar, greatly improving the pipe stiffness to adapt to the environment and laid in a variety of soil seabed. ◎ excellent mechanical properties within the water glass pipe surface is very smooth, friction is small (n≤0.0084), can significantly reduce the pressure loss along the way, increasing the flow of traffic in the same circumstances, you can use a smaller diameter or power than the small pump, thereby reducing the initial investment project, saving energy consumption (lower operating costs). ◎ good can be designed to adapt to a wide range by changing the selection, and design ply winding angle to accommodate different working pressures, media, stiffness (or burial depth) requirements, thereby producing different pressure levels and the special properties of glass pipes . ◎ pollution, toxic smooth inner wall scaling, do not breed algae and other microorganisms, water quality, no secondary pollution. Produced through the use of food-grade resin may be used for conveying potable water piping. ◎ fewer joints, sealing glass pipe single length is generally 12 meters, double "O" - ring socket connection, each interface can pressure test, reliable sealing. ◎ light weight, easy to transport, install only the weight of GRP pipes with the specifications, with 1/4 of the length of ductile iron pipe, cement pipes 1/10. Transportation loading and unloading easy, high installation efficiency and low cost. 2.
