FRP Sandwich Tube

الوصف

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. 1. High strength: It has strong external load resistance. The GRP sand pipe can be directly buried under the carriageway without building a concrete protective layer, which can speed up the construction progress. Therefore, the construction cost is greatly reduced and has significant social and economic benefits. 2. Corrosion resistance: specially designed GRP sand pipe can resist the corrosion of many chemical fluids, such as acid, alkali, salt, untreated sewage, corrosive soil and groundwater. With the long service life of traditional pipes, its design service life can reach more than *0 years. 3. Good flame retardancy, heat resistance and frost resistance: FRP sand can be used for a long time at - *0 ℃ - **0 ℃ without deformation. 4. Good electrical insulation performance: no eddy current loss and electrical corrosion energy saving, glass fiber reinforced plastic pipe below DN**0 is suitable for cable laying; Large current carrying capacity and small thermal resistance have no adverse effect on the normal operation of the cable. 5. Quick and convenient construction and installation: the GRP sand pipe adopts the socket connection mode, which is convenient for installation and connection; Double O-ring is used at the joint to adapt to thermal expansion and cold contraction.
