Features:
◎Good corrosion resistance and long service life
FRP pipes can resist long-term corrosion of various acids, alkalis, salts, organic solvents, seawater, sewage and other chemical media.Pipelines with different properties can be selected according to different media types and operating temperatures.
◎Excellent mechanical properties
FRP pipes have a small specific gravity (1.8~2.1g/㎝3) and high strength (≥300MPa), and their specific strength is much greater than that of steel pipes and cast iron pipes. Due to the addition of resin mortar in the middle layer of the pipe wall, the rigidity of the pipe is greatly improved, and it is suitable for various.
◎Excellent hydraulic performance
The inner surface of the FRP pipe is very smooth and the friction resistance is small (n≤0.0084), which can significantly reduce the pressure loss along the way and increase the flow rate. Under the same flow rate, a smaller pipe diameter or a lower power delivery pump can be selected.Thereby reducing the initial investment of the project and saving energy consumption (reducing operating costs).
◎Good designability and wide application range
FRP pipes with different pressure levels and special properties can be made by changing the material selection, winding angle and layer design to meet different working pressure, medium, rigidity (or buried depth) requirements.
◎Anti-fouling, non-toxic
The smooth inner wall does not scale, does not breed algae and other microorganisms, and has no secondary pollution to water quality. Pipes made of food-grade resin can be used to transport drinking water.
◎Few joints, good sealing performance
The length of a single FRP pipe is generally 12 meters, and it is connected by double "O"-shaped sealing rings. Each interface can be tested for pressure, and the seal is reliable.
◎Light weight, easy to transport and install
The weight of FRP pipes with sand is only 1/4 of that of ductile iron pipes of the same specification and length, and 1/10 of that of cement pipes. The transportation and loading and unloading are convenient, the installation efficiency is high, and the cost is low.
