With the development of technology, the technology for manufacturing fiberglass reinforced plastic storage tanks is becoming increasingly advanced. Nowadays, FRP storage tanks have been upgraded from the previous hand lay-up technology to the current seamless winding technology of FRP fibers. So, how are FRP storage tanks wound? Let the editor introduce it to you.

FRP storage tanks are all composed of a corrosion-resistant inner lining layer with high resin content, a seepage prevention layer, a fiber-wound reinforcing layer and an outer protective layer. In fact, the sealing performance of mechanically wound FRP storage tanks is relatively good.

The winding technology of FRP storage tanks is divided into two major categories: straight winding (ring winding) and oblique winding. As for FRP tanks with relatively small cubic meters, such as 2-cubic-meter FRP tanks, the formwork + straight winding method can be used for production. For those FRP tanks with larger volumes, those of 3 cubic meters or more must be fabricated using the formwork + oblique wrapping technique.

Second, both diagonal winding and straight winding have their own functions: Diagonal winding of FRP tanks can make them more sturdy and durable, while straight winding can make the surface treatment of FRP tanks smoother, less marked and more elegant. It is indispensable to make a fiberglass reinforced plastic tank with both diagonal and straight winding.

During the design process of FRP storage tanks, it is necessary to know the temperature and pressure of the medium to be stored in the tank, as well as the maximum operating pressure, the highest operating temperature and the lowest operating temperature, the corrosiveness, properties, vapor pressure, inlet and outlet volume of the medium, etc. These data are collected as the basic data for the design.
