cryogenic CO2 tank

At low temperatures, CO2 has a low gas pressure. Tanks must be designed to withstand the pressure changes at low temperatures while avoiding abrupt changes between liquid and gas. As the temperature rises, the gas pressure of CO2 increases, which creates a greater pressure burden on the tank. Tank designs for high temperatures require additional pressure vessel safety design considerations, including pressure control valves and safety valves.

Cryogenic tanks are often called cryogenic tanks or liquid nitrogen tanks. The structure can be divided into two layers. The first layer is an inner layer made of austenitic stainless steel.

The cryogenic liquid CO2 storage tank is double walled. The internal material uses 16mndr stainless steel and the external material uses q245r carbon steel.
