Product Overview:
Advantages of FRP sand-filled pipes:
1. Good corrosion resistance, no effect on water quality:
FRP pipes can resist erosion by acids, alkalis, salt, seawater, untreated sewage, corrosive soil or groundwater and many chemical fluids.
2. Anti-fouling and anti-insect:
The surface of unsaturated polyester resin is clean and smooth and will not be contaminated or damaged by microorganisms such as shellfish, fungi, etc. in the ocean or sewage.
3. Good heat resistance and frost resistance:
At -30℃, it still has good toughness and extremely high strength, and can be used for a long time in the range of -50℃-80℃. The specially formulated resin can also work at temperatures above 110℃.
4. Light weight, high strength, easy transportation and installation;
Its specific gravity is 1.65-2.0, only 1/4 of that of steel. Its circumferential tensile strength is 180-300MPA, and its axial tensile strength is 60-150MPA. It adopts socket connection method, and its installation is quick and easy.
5. Small friction resistance and high conveying capacity:
The inner wall of the FRP pipe is very smooth, with little roughness and friction. The roughness coefficient is 0.0084, and the N value of the concrete pipe is
0.014, and the cast iron pipe is 0.013. Therefore, the FRP pipe can significantly reduce the fluid pressure loss along the process and improve the conveying capacity.
6. Good electrical and thermal insulation:
The insulation resistance is 1012-1015ΩCM. The heat transfer coefficient of FRP is very small, only 0.23, which is 50/thousandth of steel.
7. Good wear resistance:
8. Low maintenance cost:
No anti-rust, anti-fouling, insulation, heat preservation and other measures and maintenance are required. No barrier protection is required for buried pipes, which can save more than 70% of engineering maintenance costs.
9. Strong adaptability:
According to the various specific requirements of users, such as different flow rates, different pressures, different burial depths and load conditions, pipelines with different pressure levels and stiffness levels can be designed and manufactured.
10. The project has a long service life and is safe and reliable.
According to laboratory simulation tests, the service life of FRP pipes can be more than 50 years.
11.Good comprehensive benefits of the project:
The comprehensive benefits of FRP pipes are desirable. In particular, the larger the pipe diameter, the lower the cost. When considering that the pipe buried underground can be used for several generations and does not need to be inspected every year, its comprehensive benefits can be brought into full play.

Application Industry
New Development in the Fiberglass
In recent years, fiberglass - reinforced plastic has shown great potential in numerous fields and has become a dazzling star in the materials field.
In the construction industry, fiberglass - reinforced plastic is widely used for its lightweight and high - strength characteristics. Compared with traditional building materials, the weight of fiberglass - reinforced plastic can be reduced by 30% - 50%, but its strength can reach or even exceed that of some metal materials. For example...
Fiberglass - Reinforced Plastic: A Multifunctional Material with Remarkable Advantages
Fiberglass - reinforced plastic, a composite material using glass fibers and their products (such as glass cloth, tape, mat, yarn, etc.) as reinforcing materials and synthetic resins as matrix materials, is playing an increasingly important role in numerous industries, and its many advantages make it highly favored.
