Liquid argon tank is a double fixed vacuum powder adiabatic tank (tank). The inner tank is made of stainless steel (carbon dioxide storage tank is 16MnDR), and the outer tank is made of Q235B or 16MnR. The surface anticorrosion coating adopts sand blasting, cleaning, spraying and other processes. Meanwhile, two-component fast curing liquid coating is adopted. This series of products are mainly used for liquid storage of liquid oxygen, liquid nitrogen, liquid argon and carbon dioxide at low temperature. One cubic meter of liquid can replace 130 gas cylinders. It can replace the daily cylinder transport, save a lot of human and material resources. This series of products are characterized by long service life, compact structure, small floor space, centralized control and easy operation. This product is widely used in gas industry, hospital, metal smelting and other users with large gas consumption, and is the best product to realize centralized gas supply.

Liquid argon is stored in a dewar tank as a liquid and is released in the gas phase when used. When the liquid argon is stored in the duw tank, it will undergo a natural pressurization process. When the pressure is too high, the duw tank will release the pressure safely. During this natural pressurization and pressure relief process, argon will be released naturally.
