FRP Sand Pipe
Fiber-wound glass fiber reinforced plastic sandwich pipe has reliability, safety and economy. It is mainly used in buried pipes and long-distance pipelines. It has the characteristics of light weight and high strength, corrosion resistance, long service life, and low operating and maintenance costs. It can be used for construction The project saves a lot of money.
1. Lightweight and high-strength: The proportion of glass fiber reinforced plastic sand pipe is 1.65 ~ 2.0. For the unit length weight of the same pipe diameter, only 1/3 of carbon steel, FRP pipe is only 1/5 of cast iron pipe, 1/10 of prestressed concrete pipe, reducing hoisting costs and increasing installation speed during construction. .
2. Good hydraulic characteristics: This characteristic is particularly prominent in the field of water supply and drainage, and its hydraulic characteristics are good.
(1) It can save the pumping cost of the pipe network. (2) Reduce the pipe diameter. (3) Shorten the pumping time.
(4) The FRP pipe does not scale up for long-term delivery of water and does not need to be cleaned, so that the water quality is not subject to secondary pollution.
3. Good water and corrosion resistance: FRP sand-filled pipes have excellent corrosion resistance, which reduces the cost of anticorrosion and prolongs the service life. At the same time, because it does not rust, the water quality of the water is not subject to secondary pollution. It can also be used to transport sewage, mud, seawater and other media.
4. Pressure resistance: Design and manufacture pipes and fittings according to the pressure required by the process, and perform a hydraulic test at 1.5 times the pressure required by the process.
5. The interface has good sealing performance, no leakage, no breakage, and increased water supply safety and reliability.
6, non-toxic, can be used to transport drinking water.
◆ Drinking water pipelines and water distribution pipes
◆ Sewage pipeline, rainwater pipeline
◆ Agricultural irrigation pipe
Third, the main molding process
Controlled by a computer, the lining is manufactured on the core mold according to the same process as fiber-wound glass steel pipe. After the gel, the structure layer is wound according to the designed line type and thickness, and the mortar mixed with quartz sand and resin is wrapped around the structure In the layer, the outer protective layer is finally wound.
4. Raw and auxiliary materials: resin, chopped fiber, continuous glass fiber and quartz sand.
