Although the liquid nitrogen tank stores compressed and cooled nitrogen, the liquid nitrogen tank is not a pressure vessel. The principle to store the liquid nitrogen in a liquid nitrogen tank is mainly through the special physical structure of the liquid nitrogen tank which can reduce the heat exchange occurs inside and outside the tank, so that the temperature in the liquid nitrogen tank has been kept usually below -196 °C. At this temperature, nitrogen will always be in a liquid state, so a good liquid nitrogen tank can store liquid nitrogen for a long time.
