Jianshentank on the anticorrosion of cryogenic storage tank
Date: Aug 11, 2020
The 
cryogenic storage tank is a double-layer container composed of an inner and an outer container. It is a type of vacuum powder insulation, which can be divided into vertical and horizontal. Cryogenic liquid cryogenic storage tanks use "combination and safety system valves". Two sets of safety valves can be used at the same time. After checking the safety valve regularly, one side can be closed and the other side can continue to work to ensure the safe operation of the storage tank.
Jianshentank believes that the anti-corrosion and anti-corrosion work of cryogenic storage tanks can only ensure that its functional advantages can be exerted in many aspects without disturbing everyone's normal work.
How to effectively store cryogenic storage tanks? Jianshentank suggests that you can start from the following aspects:
⑴Physical anti-corrosion effect, by properly blending with pigments that can react with oily film-forming agent, a good anti-corrosion coating can be obtained, thereby enhancing the physical anti-corrosion effect. For example, the reaction of lead-containing pigments and oils to form lead soap will make the anti-corrosion coating thinner and then reduce the penetration of harmful substances such as water and oxygen. 
⑵ Chemical antiseptic effect. When harmful acidic and alkaline substances enter the anti-corrosion coating, they can be neutralized into harmless substances. This is also a useful anti-corrosion method. Choose amphoteric compounds, such as zinc oxide, aluminum hydroxide, barium hydroxide, etc. , Can easily stop the neutralization of acidic or alkaline harmful substances and play a preservative effect, and may react with water and acid to form alkaline substances.
⑶ Electrochemical anti-corrosion effect. When the water and oxygen entering from the pinhole of the coating pass through the anti-corrosion coating, the loose anti-corrosion pigment in the anti-corrosion coating constitutes anti-corrosion ions, which are rich in anti-corrosion ions. Moisture reaches the metal surface to passivate the steel surface and prevent iron ions from dissolving. Chromate pigments have this characteristic.
