What is FRP sand pipe?
Glass fiber reinforced plastic sand pipe is a new composite material made of resin as matrix material, glass fiber and its products as reinforcement material and quartz sand as filling material. Because of its excellent corrosion resistance, hydraulic characteristics, light weight and high strength, large conveying flow, convenient installation, short construction period and low comprehensive investment, it has become the best choice for chemical engineering, drainage engineering and pipeline engineering.
Advantages of FRP sand pipe:
1, Corrosion resistance: FRP sand pipe is made of resin with strong corrosion resistance and has excellent mechanical properties and processing characteristics. It is corroded in acid, alkali and salt seawater, most untreated sewage, corrosive soil or groundwater and many chemicals.
2. Heat resistance and cold resistance: FRP sand pipe still has good toughness and extremely high strength at -30℃, and can be used for a long time at -50℃-80℃, and the resin with special formula can also be used at 1 10℃.
3. Good wear resistance: FRP pipes have good wear resistance. The test shows that the water containing a lot of mud and sand is put into the pipe to carry out the comparative test on the influence of rotary wear. After 300,000 revolutions, the wear depth of the inner wall of the pipeline is: (1) the steel pipe coated with tar and porcelain oil is 0.53mm, the surface hardened steel pipe is 0.48mm, and the glass fiber reinforced plastic pipe is 0.2 1mm, which shows that the glass fiber reinforced plastic pipe has strong wear resistance.
4. Long service life, safety and reliability: the design safety factor of glass fiber reinforced plastic sand pipe is high. According to the laboratory simulation test table, the service life of glass steel pipe for water supply and drainage with sand can reach more than 50 years, which is twice as long as that of steel pipe and concrete pipe. For corrosive media, its service life is much longer than that of steel pipe.
In addition, FRP sand pipe has many advantages, such as excellent thermal insulation performance, few joints, high installation efficiency, small specific gravity, light weight, good mechanical properties, energy saving and so on.

Connection mode of glass fiber reinforced plastic sand pipe:
The connection of glass fiber reinforced plastic sand pipe consists of special rubber liner and glass fiber reinforced plastic outer wall. Full surface thermal (positive compensation) crosslinking is adopted, which has reliable mechanical properties, corrosion resistance and sealing performance. In general, the use of socket sealing connection can ensure fast, accurate, time-saving and labor-saving. In addition, other connection methods such as flange connection can also be used.
