FRP storage tank is a new type of composite material made of glass fiber as reinforcement and resin as adhesive through microcomputer controlled machine winding. FRP storage tank has corrosion resistance, high strength, light weight and long service life. Because it also has the characteristics of flexible design and strong manufacturability, it can be flexibly designed and applied in different industries, such as chemical industry, environmental protection, food, pharmaceutical and other industries. The following takes chemical FRP storage tank as an example to introduce the product characteristics and inspection standards.

Chemical FRP storage tank features:

1、 It has excellent physical functions: the specific gravity of FRP is generally 1.8-2.1, which is 1 / 4-1 / 5 of that of steel, which 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 is only 0.5% of that of steel.

2、 Chemical corrosion resistance and long service life: FRP has special corrosion resistance function. When storing corrosive media, FRP storage tanks can withstand a variety of acids, alkalis, salts and organic solvents.

3、 The planning flexibility is large, and the tank wall structure function can be customized: the fiber wound FRP can change the resin system or reinforcement data to meet the needs of different media and working conditions. Through the structural layer thickness, winding angle and wall thickness structure and planning, the bearing capacity of the tank body is adjusted to make FRP storage tanks and non-standard equipment with different pressure levels or some specific functions.

Inspection standard for chemical FRP storage tank:

The main inspection standards for FRP tanks are: whether the surface of FRP tanks is flat and smooth, free of impurities, exposed fibers, visual cracks, obvious scratches, white flowers and delamination; The outer surface shall be flat and smooth without fiber exposure, obvious bubbles and serious uneven color.

The above are some characteristics and inspection standards of chemical FRP storage tanks. I hope it will be helpful for you to understand FRP storage tanks after reading this article.
