FRP fiberglass pipes are wound and molded with high-strength fiberglass, with quartz sand added inside to improve structural rigidity. They feature excellent acid and alkali resistance, resistance to soil settlement, light weight and smooth inner wall with low water resistance. Widely used in municipal rainwater and sewage drainage, chemical corrosive fluid transportation, seawater conveyance, farmland irrigation and power plant circulating water projects. The service life can reach more than 50 years. It is easy to install with almost no later maintenance, and the overall project cost is lower than concrete pipes and steel pipes, making it an ideal anti-corrosion pipe for underground pipeline networks.
