Advantages of Fiberglass Sand-Filled Pipes:

1.Good Corrosion Resistance, No Impact on Water Quality:

Fiberglass pipes can resist corrosion from acids, alkalis, salts, seawater, untreated wastewater, corrosive soils, groundwater, and various chemical fluids.

2.Anti-Pollution and Termite Resistance:

The smooth surface of unsaturated polyester resin resists fouling and infestation by microorganisms such as barnacles or fungi found in seawater or wastewater.

3.Excellent Heat and Freeze Resistance:

These pipes maintain good toughness and strength at -30℃ and can be used in temperatures ranging from -50℃ to 80℃. Pipes made with specially formulated resin can even operate above 110℃.

4.Lightweight and High-strength, Easy to Transport and Install:

The specific gravity is between 1.65 and 2.0, only a quarter of steel’s weight. Circumferential tensile strength ranges from 180-300 MPa, and axial tensile strength ranges from 60-150 MPa. The socket joint design makes installation quick and easy.

5.Low Friction, High Transport Capacity: The inner wall of fiberglass pipes is smooth, with a low roughness coefficient. Its roughness is 0.0084, compared to 0.014 for concrete pipes and 0.013 for cast iron pipes, significantly reducing fluid pressure loss and increasing transport capacity.

6.Good Electrical and Thermal Insulation:

The electrical insulation resistance is between 1012-1015Ω, and the heat transfer coefficient is only 0.23, much lower than that of steel (5/1000).

7.Good Abrasion Resistance

8.Low Maintenance Costs: They require minimal maintenance, with no need for rust-proofing, anti-fouling, insulation, heat preservation and other measures and maintenance. Buried pipes don’t need cathodic protection, reducing maintenance costs by over 70%.

9.High Adaptability:

Fiberglass pipes can be customized to different pressure and stiffness ratings based on user requirements.

10.Long Lifespan, Safety, and Reliability:

Laboratory tests have shown that fiberglass pipes can last over 50 years.

11.Excellent Overall Economic Benefits:

Fiberglass pipes offer significant economic advantages, especially for larger diameters, where their costs are lower. Long-lasting and with minimal need for repairs, these pipes provide outstanding long-term value.
