Fiber-wound FRP pipes are made with thermosetting polyester resin as the matrix, glass fiber and its products as reinforcing materials, and are produced using reciprocating winding computer-controlled production technology.

　　1. Product performance characteristics

　　1. Corrosion resistance: It has good resistance to the atmosphere, water and general concentrations of acids, alkalis, salts and various oils and solvents.

　　2. Light weight: excellent physical properties, lightweight and high strength: density 1.5~2.0g/cm3, which is 1/4~1/5 of steel. But the tensile strength is close to steel, up to 400MPa.

　　3. Long service life: up to more than 50 years.

　　4. The inner wall is smooth, the absolute roughness is 0.0084, and the flow rate of the same pipe diameter is 15% to 20% greater than that of other pipes.

　　5. The construction is simple, the construction efficiency is high, and the installation speed is 5 to 10 times that of other pipes.

　　6. It has strong designability, no scaling on the pipe wall, and no secondary pollution to the water quality. By choosing food-grade lining resin, it can meet the requirements of GB 5749 "Hygienic Standard for Drinking Water" and the British WRAS drinking water safety certification.

　　2. Wide application fields

　　Due to its extremely excellent cost performance and wide range of applications, FRP pipes have been widely used in various fields such as electric power environmental protection, municipal construction, petrochemical industry, and marine ships.

　　3. Product specifications
