FRP sand pipe is a new composite material made of resin as the matrix material, glass fiber and its products as the reinforcement material, and quartz sand as the filling material. It has become the best choice for chemical industry, drainage engineering and pipeline engineering due to its excellent corrosion resistance, hydraulic characteristics, light weight and high strength, large transmission flow, convenient installation, short construction period and low comprehensive investment. The resin with strong corrosion resistance is selected, which has excellent mechanical properties and processing characteristics, and can withstand the corrosion of most untreated sewage, corrosive soil or groundwater, and many chemicals in acid, alkali, salt and seawater. The abrasion resistance of glass fiber reinforced plastic pipe is very good. The test proves that the water containing a large amount of mud and sand is put into the pipe for a comparative test on the impact of rotating abrasion. After 300000 rotations, the wear depth of the inner wall of the pipe is tested as follows: the steel pipe coated with tar and porcelain oil is 0.53mm; The surface hardened steel pipe is 0.48mm; The glass fiber reinforced plastic pipe is 0.21mm, which indicates that the wear resistance of glass fiber reinforced plastic pipe is very strong.
