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 pipeline installation sequence is based on the division of areas and systems. The large diameter is first followed by the small diameter, the lower layer is first followed by the upper layer, and the difficulty is first followed by the ease. The pipeline connected to the machine is in principle from the inside out to reduce the impact of welding stress on the installation accuracy of the machine. The interface between indoor and outdoor pipelines should be left outside.
