FRP Sand-Filled Pipe is the result of research and development for many years. And it is the second new material to stress concrete pipe, ductile cast iron pipes used in large fluid transport projects, it mainly used for underground pipe, overhead pipe, meanwhile it has the characteristics of light weight, high strength, corrosion resistance, long service life, low operation and maintenance cost, so it can save a lot of money for construction project.

The main molding process is controlled by computer, firstly, on the core mold according to the provisions of the process to produce liner(the same as fiber wrapped glass tube), After the gel was designed according to the design of linear and thickness of the structure layer, and the quartz sand and resin mixed mortar wrapped in the structure layer, the final wound protection layer.
