Quality assurance of FRP pipe manufacturer

FRP pipe 1. Good corrosion resistance; Filament wound glass Steel pipe The tunnel structure is divided into three parts: inner lining, structural layer and outer protective layer. Among them, the resin content of the inner liner is high, generally more than 70%, and the resin content of the resin rich layer on the inner surface is up to 95%. 2. Excellent hydraulic performance; The inner surface of the wrapped FRP pipe is smooth, and the roughness of the inner wall is only 0.01mm, which is far less than the roughness of the inner wall of steel pipes and cast iron pipes. 3. Light weight, convenient installation and transportation; Under the same pressure, the weight of FRP pipes with the same diameter and length is about 30% of that of steel pipes. 4. High specific strength and reasonable mechanical properties; The axial tensile strength of wrapped FRP pipe is 160~320MPa, which is close to that of steel pipe and has higher specific strength, Pipe The dead weight can be greatly reduced, and the installation is very easy. 5. Low thermal conductivity, low thermal stress, 6. Good electrical insulation, no rust
