Liquid nitrogen tanks are generally divided into two types: liquid nitrogen storage tanks and liquid nitrogen transport tanks. The storage tank is mainly used for indoor static storage of liquid nitrogen. It is not suitable for long-distance transportation under working conditions. The liquid nitrogen transportation tank has a special shockproof design in order to meet the transportation conditions. In addition to storage, it can also be used for transportation in a state filled with liquid nitrogen, but it should also avoid severe collisions and vibrations.
