Fiberglass Reinforced Plastic (FRP) Sand Lined Pipes _ Features of FRP Sand Lined Pipes

1. Strongly corrosion-resistant glass fiber reinforced plastic (GRP) sand-laying pipes are acid, alkali, and corrosion-resistant to soil erosion, capable of conveying groundwater, seawater, factory wastewater, and highly corrosive liquids. Special pipes are manufactured with appropriate corrosion-resistant materials based on the conveyed medium, while maintaining all the original characteristics of the GRP product (lightweight, high strength, corrosion resistance, insulation, heat insulation, and design flexibility).

2. The abrasion-resistant glass fiber reinforced sand-laying pipes exhibit excellent wear resistance. Tests show that when a slurry containing a large amount of silt, sand, and stones is poured into pipes of different materials and the pipes are rotated for 10,000 rotations, the glass fiber reinforced sand-laying pipes maintain their integrity. 3. Withstanding heat, frost, and strong temperature adaptability, the glass fiber reinforced sand-laying pipes can operate normally at temperatures ranging from -40℃ to 80℃. Pipes with special resin ratios can operate at temperatures as high as 110℃, and they do not crack under frozen media.

4. The inner wall of the sand-laminated glass fiber reinforced plastic pipeline has a smooth surface, low resistance, with a roughness coefficient of 0.0084 and a hydraulic resistance coefficient approximately half that of steel pipes and one-fourth that of cement pipes. The head loss due to fluid pressure is minimal, ensuring the ability to transport larger volumes at a smaller diameter. Typically, sand-laminated pipes are one grade smaller in diameter selection than cast iron or cement pipes. If pipes with the same inner diameter are used, the pump power and energy consumption can be reduced by one-third.

5. High mechanical strength GRP sand-laying pipes exhibit excellent water pressure resistance, external pressure resistance, and impact resistance, making them suitable for installation under various geological conditions. They can also be custom-designed and manufactured to meet customer-specified pressure requirements for pipes and fittings.

6. Water Quality Maintained: Glass-fiber Reinforced Plastic (GRP) sand-laying pipes are non-toxic products, ensuring that the annual drinking water transported maintains long-term water hygiene.

7. Lightweight and easy to install, the glass fiber reinforced sand-filled pipes have a low density, just 1/4 of steel pipes and 1/10 of cement pipes. They are suitable for annual loading and unloading, with low installation costs. The length of the sand-filled pipe sections can reach 12 meters, requiring fewer joints for installation, and no need for complex welding, anticorrosion treatment, or cathodic protection. Special equipment is not required, and professional technicians are on-site to guide the installation to ensure the quality of the project.

Fiberglass Reinforced Plastic (FRP) sand lined pipe's primary molding process

In the mandrel, the inner lining is manufactured according to the same process as the fiber-wrapped glass steel pipe, followed by curing and wrapping the structural layer with the designed profile and thickness. Then, a mortar mixed with quartz sand and resin is wrapped between the structural layers. Finally, an outer protective layer is wrapped around.
