FRP pipes can resist the erosion of acid, alkali, salt, seawater, untreated sewage, corrosive soil or groundwater and many chemical fluids. The service life is longer than that of traditional pipes, and its design service life is generally more than 50 years. Sand-filled GRP pipes produced by filament winding are used.

The proportion of GRP is 1.65-2.0, only 1/4 of steel, but the hoop tensile strength of GRP is 180-300MPa, and the axial tensile strength is 60-15OMPa, which is similar to alloy steel. The comprehensive benefit refers to the long-term benefit formed by construction investment, installation and maintenance costs, service life, energy saving and steel saving and other factors. The comprehensive benefits of FRP pipes are desirable. The larger the pipe diameter, the lower the cost.

The fiberglass products are mainly made of glass fiber, which is a composite material and is generally very corrosion resistant. The corrosion resistance life is generally more than 20 years. The components and performance of the civil air defense water tank are composed of resin paste (matrix material) and glass fiber (reinforcement material).
