FRP corrosion-resistant equipment can change the resin system and reinforced materials to meet the special needs of users. The height can be from 1m to 16m. The molding is controlled by a microcomputer. The corrosion-resistant and anti-seepage lining layer is first made on the steel mandrel, and then according to the design Wrap the structural layer with good line shape and thickness, and finally make the outer protective layer.

　　FRP and engineering plastic composite structures can also be used: FRP/PVC, FRP/PP, FRP/PVDF, etc.

　　1. Basic features:

　　Excellent physical properties: The specific gravity of FRP is only 1/4 to 1/5 of steel, and its specific strength is higher than 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.

　　Resistant to chemical corrosion and long service life: FRP has special corrosion resistance. When storing corrosive media, FRP shows advantages that other materials cannot match. It can resist a variety of acids, alkalis, salts and organic solvents.

　　Great design flexibility and excellent tank wall structural performance: the resin system and reinforcing materials can be changed to improve the physical and chemical properties of FRP to adapt to the needs of different media and working conditions. The load-bearing capacity of the equipment can be adjusted through the thickness of the structural layer, winding angle and wall thickness structure and design. It can withstand different pressure levels or meet certain special properties, which isotropic metal materials cannot compare with them.
