There are two main types of storage containers for liquid nitrogen tanks: low-temperature tank (mobile or fixed) and liquid nitrogen biological storage tank. Low temperature tank is a closed pressure vessel, with the tank body wrapped in a vacuum layer and a filling layer, providing insulation effect. The liquid nitrogen biological storage tank is an open insulation tank, also wrapped in a vacuum layer, but the tank mouth can be opened and there is no pressure inside the tank.

Hydrochloric acid containers are usually designed in a vertical cylindrical shape to meet the needs of large-scale storage. The tank body is welded from steel plates and has undergone special treatment inside to prevent corrosion of the material by hydrochloric acid. At the same time, the storage tank is also equipped with inlet and outlet pipelines, safety valves, liquid level gauges and other auxiliary equipment to facilitate operation and management.
