Fiberglass reinforced sand pipes belong to which type of pipeline? Fiberglass reinforced sand pipes, abbreviated as fiberglass reinforced plastic pipes, are a new type of flexible non-metallic (resin, fiber, sand, etc.) composite material pipes. Most pipe manufacturers generally use three processes: fixed-length winding, centrifugal casting, and continuous winding.
What type of pipeline does the fiberglass sand pipe belong to?
Fiberglass sand pipe, abbreviated as fiberglass reinforced plastic pipe, is a new type of flexible non-metallic (resin, fiber, sand, etc.) composite material pipe. Most pipe manufacturers generally use three processes: fixed-length winding, centrifugal casting, and continuous winding. This is a type of flexible composite material (resin, fiber, sand, etc.) pipe that is gradually becoming popular both domestically and internationally.
The fiberglass sand pipe is not only lightweight (only1/9 to 1/5 of concrete pipes), has good pressure-bearing capacity (internal pressure range of 0.4 to 2.5 MPa), and low liquid transmission resistance (roughness coefficient n=0.009), which can ensure water supply quality, is resistant to chemical and electrical corrosion, and has advantages such as easy installation, long service life, moderate overall cost, simple operation, and low maintenance costs. It is suitable for urban water supply, sewage discharge, industrial water treatment, industrial liquid transportation, and other gravity or pressure transportation systems. Therefore, FRP pipes are a new type of pipe material with broad development prospects.
A significant feature of the fiberglass sand pipe is that it can choose different lining resins according to different applications, making it suitable for transporting various fluids. The resin lining can be used as a water supply pipeline, and anti-corrosion resin lining can also be used as a sewage pipeline. Especially in applications involving the transportation of highly corrosive industrial wastewater, it outperforms other pipes and has achieved good results. The main application fields of fiberglass sand pipes include: drinking water transport pipes; sewage collection pipes, reclaimed water pipes; municipal water supply and drainage pipes; seawater transport pipes and various other underground pipes. Fiberglass sand pipes have good corrosion resistance and a long service life. Fiberglass pipes can withstand long-term corrosion from various acids, bases, salts, organic solvents, seawater, sewage, and other chemical media. Different types of pipes can be selected based on different media types and working temperatures. Fiberglass sand pipes have excellent mechanical properties.GRP pipes have a small specific gravity, high strength, and specific strength far greater than that of steel pipes and cast iron pipes. Because it involves the resin mortar in the middle layer of the pipe wall, it greatly improves the rigidity of the pipe, making it suitable for laying in various soil environments and seabeds. The hydraulic performance of FRP pipes is excellent, with a very smooth inner surface and low friction resistance.
It can significantly deter pressure loss along the way and increase flow rate. At the same flow rate, a smaller pipe diameter or a smaller power delivery pump can be selected, thereby reducing initial investment in the project and saving energy. Fiberglass reinforced plastic sand pipes have good programmability and wide habitual planning, which can be adjusted according to different working pressures and media habits by changing material selection, winding angles, and layered planning rigidity requirements. Then, pipes with different pressure ratings and special functions are produced.FRP pipes; fiberglass reinforced plastic sand pipes are anti-pollution, with smooth inner walls that do not accumulate scale, algae, or other microorganisms, positively affecting water quality without secondary pollution. Pipes made from food-grade resin can be used for transporting drinking water; fiberglass sand pipes have fewer joints and good sealing performance. The length of a single fiberglass reinforced plastic pipe is usually 12 meters, using double "O"-ring socket connections, and each joint can be pressure tested, ensuring reliable sealing.
Fiberglass sand pipes are lightweight and easy to transport. They are used for equipment.The weight of GRP sand pipes is only 1/4 of that of ductile iron pipes of the same specification and length, and 1/10 of that of cement pipes used for transportation and loading, making them convenient, efficient, and cost-effective. The main raw materials for fiberglass sand pipes include: resin: different functional resins can be selected according to different application requirements; continuous glass fiber; quartz sand; glass fiber mat, etc.
