The specific gravity of FRP is usually 1.8-2.1, which is 1/4-1/5 of steel, and its specific strength is higher than that of steel, cast iron and plastic. The thermal expansion coefficient of FRP is roughly the same as that of steel, and the thermal conductivity coefficient is only 0.5% of that of steel.

FRP containers and FRP storage tanks are resistant to chemical corrosion and have a long service life: FRP has special corrosion resistance. When storing corrosive media, FRP shows much better than other materials, and can resist a variety of acids, alkalis, salts and organics. solvent.

FRP containers and FRP storage tanks have great design flexibility and excellent tank wall structure performance: fiber wound FRP can change the physical and chemical properties of resin systems or reinforcing materials to high-speed FRP storage tanks and non-standard devices to meet the needs of different media and working conditions . The bearing capacity of the tank is adjusted through the structure and design of the thickness of the structural layer, the winding angle and the wall thickness, and the FRP storage tanks and non-standard devices with different pressure levels or some special properties are made. compared
