1. Corrosion-resistant FRP pipes can resist the corrosion of acid, alkali, salt, seawater, untreated sewage, corrosive soil or groundwater and other chemical fluids.
2. 具有良好耐热性和抗冻性的玻璃钢管的温度范围一般在-40℃~ 80℃之间。如果先用特殊的树脂，温度会更高。
2. The temperature range of FRP pipes with good heat resistance and frost resistance is generally between - 40 C and 80 C. If special resin is used first, the temperature will be higher.
The specific gravity of FRP tube is 1.7-1.9. Compared with other materials with the same pressure and diameter, the unit length and weight of FRP pipe are about 30% of that of steel pipe. Therefore, it is very convenient to transport and install. In addition to installation of steel pipes need welding anti-rust, anti-corrosion treatment and other procedures.
The inner surface of FRP pipe is smooth and its roughness coefficient is small. Hydraulic coefficient C can be maintained in the range of 145-150 for a long time. The experimental results show that the friction loss coefficient f of flow is 0.000915, which can significantly reduce the fluid pressure loss along the flow and improve the conveying capacity by more than 20%.
5. Good electrical and thermal insulation FRP is non-conductor, pipeline insulation is very good, the most suitable for use of transmission, telecommunications line density area and minefield, the heat transfer coefficient of FRP pipe is very small (0.25 kcal/m.h.C), so the insulation of the pipe is good, less heat loss.
6. Non-rusting is because the glass tube is made of non-metallic resin and glass fibre. Therefore, no rust will occur in the process of use or idle, so there is no need for rust prevention and removal. 7. The specific performance and shape of wrapped FRP pipes can be designed according to the specific application conditions.
(1) The winding angle can be designed to make the pipeline have different longitudinal/annular strength distribution.
(2) The wall thickness can be designed so that the wall can withstand different internal and external pressures.
(3) The material can be designed to achieve corrosion resistance, flame retardancy and dielectric properties for different purposes.
(4) According to different installation conditions, suitable head can be designed to improve the speed of Engineering installation.
8. Connection modes are various flexible connection modes of winding FRP pipes, including flat-end docking, (circular) flange connection, socket insertion glue connection, (with locking device), O-ring connection, screw connection, etc. According to specific construction conditions, flexible selection of joint modes can improve the reliability of the project.
9. Repairability is strong, maintenance is convenient, no rust, no scaling, winding FRP water tank corrosion resistance is good, generally do not need maintenance; even if need maintenance, because of its light weight, strong maintainability, maintenance is very convenient.
