What are the advantages of FRP pipe manufacturing process?

1. Strong corrosion resistance. GRP pipes are resistant to acid, alkali, salt, sea water, untreated sewage, corrosive soil and various chemical fluids. Generally, the service life of plastic pipes is 3 years, that of cast iron pipes is 5-10 years, that of steel pipes is only 15 years, and that of GRP pipes is up to 50 years.

2. It has good heat resistance, anti-freezing and anti-algae functions. The working temperature of GRP pipes is generally between 40 ℃ and 80 ℃. If special resin is used, its application temperature will be higher, and it will not deform in hot summer. The inner and outer surfaces of GRP pipes are permanently lubricated, and they are not attached to various microorganisms in the culture medium, which will not cause algae.  l or cement pipes will produce algae with the passage of time, which will directly affect the service life.

3. Light weight, high strength and convenient transportation. The specific gravity of GRP pipes is 1.9-2.2g/cm3, the circumferential tensile strength of pipes can reach 320MPa, and the axial tensile strength can reach 230MPa. Compared with other raw material pipes of the same pressure and diameter, the composition of each unit length of glass sand pipe accounts for about 30% of the steel pipe and about 8% of the reinforced concrete pipe. Therefore, the conveying device is very convenient. The length of each FRP pipe is 12m, which can reduce two thirds of the concrete pipe. It is equipped with collar and sleeve double sealing joints. The device is fast and simple, and the combined pressure test is convenient. In addition, it can remove the welding, rust prevention and anti-corrosion treatment required for the FRP pipe of the device.

4. The scheme is safe, reliable and adaptable. Generally, the planned safety factor of the pipeline is greater than 4, which can ensure the long-term use of the product and various specific requirements of users. For example, pipe diameter, flow and pressure, mechanical function, corrosion resistance, frost resistance and use. It is planned and produced in vacuum and other environments. It is very sensitive and has a wide range of applications.

5. The project has a good inductive effect. The inductive benefits refer to the inductive costs and long-term benefits of the project. Including capital construction, installation, protection, service life of GRP pipes, energy conservation and other factors. Considering the various functions and long-term use of the pipeline, the sensing advantages of FRP pipe and FRP sand pipe are very good. In particular, the larger the pipeline, the lower the cost. The buried pipeline can be used for several generations without annual maintenance, which shows the advantages of its sensing advantages.

GRP pipe not only has the above advantages, but also has the characteristics of low friction resistance, good insulation and good wear resistance.
