Excellent mechanical propertiesFiberglass pipes have a low specific gravity (1.8~2.1g/cm3) 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, making it suitable for laying in various soil environments and underwater environments.◎ Excellent hydraulic performanceThe inner surface of fiberglass pipes is very smooth and has low friction resistance (n ≤ 0.0084), which can significantly reduce pressure loss along the way and increase flow rate. Under the same flow rate, smaller pipe diameters or lower power delivery pumps can be selected, thereby reducing the initial investment of the project and saving energy consumption (reducing operating costs).◎ Good designability and wide adaptabilityFiberglass pipes with different pressure levels and special properties can be made by changing the material selection, winding angle, and layer design to adapt to different working pressures, media, stiffness (or burial depth) requirements.Anti fouling, non-toxicThe smooth inner wall does not scale or breed microorganisms such as algae, 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 performanceThe length of a single fiberglass pipeline is generally 12 meters, and it is connected by a double "O" - shaped sealing ring socket connection. Each interface can be pressure tested and the seal is reliable.◎ Lightweight, easy to transport and installThe weight of fiberglass sand filled pipes accounts for only 1/4 of ductile iron pipes of the same specifications and length, and 1/10 of cement pipes. Convenient transportation, loading and unloading, high installation efficiency, and low cost.
