FRP pipe is a kind of non-metallic pipe, which is widely used in chemical industry and drainage industry, and has the characteristics of corrosion resistance and high temperature resistance. What are the characteristics and characteristics of FRP pipes?
　　First, the characteristics of FRP pipes
　　Has excellent corrosion resistance
　　Do not use cathodic anti-corrosion protection and other anti-corrosion measures, and will not cause secondary pollution to water and other media.
　　The weight of the pipe is only 1/4 of that of ductile iron pipes of the same specification and length, and 1/10 of that of cement pipes. Easy to transport and unload, easy to install.
　　Reduce pipeline joints, speed up installation, and improve the quality of the entire pipeline.
　　Reduce flow resistance, increase flow rate, and reduce energy consumption. Using a smaller diameter pipe to transport the fluid at the same flow rate can increase the flow rate by about 10% compared with the steel pipe of the same specification; No fouling, long-term use will not reduce the flow rate. The protection of cables in interference and heavy corrosion environments has a good effect.
　　2. Pipeline characteristics
　　(1)Corrosion resistance: chemically inert material, excellent corrosion resistance, and different corrosion-resistant pipes can be selected according to the conveying medium.
　　(2)High mechanical strength: water pressure resistance, external pressure resistance and impact resistance are all good, and pipes and fittings can be designed and manufactured according to the required pressure.
　　(3)Strong temperature adaptability: operating temperature range: greater than -70 degrees Celsius and less than 250 degrees Celsius, and the pipeline will not crack under freezing medium.
　　(4)Small fluid resistance: the inner wall of the pipe is smooth, and the roughness coefficient is 0.0084. Under the same flow rate, the pipe diameter can be reduced.
　　(5)Light weight and long life: light weight, convenient transportation, low construction cost, no maintenance, and a service life of more than 50 years.
　　(6)Maintain water quality: non-toxic, transport drinking water, can maintain long-term water quality and hygiene.
　　(一)Application of FRP sand pipes:
　　◆ Drinking water delivery trunk pipes and water distribution pipes
　　◆ Sewage pipes, rainwater pipes
　　◆ Agricultural irrigation pipe
　　(二)The main forming process of FRP pipe with sand
　　Controlled by the computer, the lining is manufactured on the mandrel according to the same process as the fiber-wound glass steel pipe. After gelling, the structure layer is wound according to the designed line shape and thickness, and the mortar mixed with quartz sand and resin is wound on the structure.
　　(三)Raw and auxiliary materials: resin, chopped fiber, continuous glass fiber and quartz sand
　　Product specification
　　Diameter: DN100-4000 Pressure rating: 0.1MPa, 0.6MPa, 1.0MPa, 1.6MPa, 2.0MPa, 2.5MPa
　　Stiffness grade:SN1250、SN2500、SN5000、SN10000。
　　Length: common 4m a piece
　　The above is the relevant introduction about the characteristics and characteristics of FRP pipes, I hope it will be helpful to everyone!FRP pipes have a much longer service life than ordinary steel pipes, are safe and reliable, and are materials that everyone has always trusted.
