Due to the good corrosion resistance of FRP storage tanks, they are more and more used in the chemical industry. The price of FRP storage tanks is mainly determined by the stored medium, structural process, thickness and quantity. The following small series will introduce them in detail.

1、 Medium stored in FRP storage tank: what medium is contained in FRP storage tank? The materials of FRP anti-corrosion layer corresponding to different media are different, which will affect the price of FRP storage tank.
1. If salt and other media are filled, it can be made of simple 191 resin and glass fiber (medium alkali or no alkali);
2. If industrial hydrochloric acid is installed, it needs to be made of 901 resin (other corrosion-resistant resins can also be used) and glass fiber (preferably alkali free);

3. If sodium hydroxide and other alkaline media are installed, it needs to be made of polyester surface felt and polyester cloth;
4. If organic medium is installed, phenolic resin will be used to produce
2、 Structural process of FRP storage tank: there are two processes of FRP storage tank: manual paste making and mechanical winding. Now mechanical winding process is widely used to make FRP storage tank. Generally, the strength of FRP storage tank with the same wall thickness made by mechanical winding method is stronger and durable than manual paste process.
3、 Thickness of FRP storage tank: FRP storage tank is divided into four layers: anti-corrosion layer, filter layer, reinforcing layer and outer surface layer. Each layer has its own design thickness. If the thickness needs to be increased according to the process requirements, the price will rise.

4、 Number of FRP tanks: the more FRP tanks of the same model, the lower the production cost.
The price of FRP storage tank is also closely related to the freight. It is suggested that the principle of purchasing nearby should be adopted, which can also save some costs.
