Liquid nitrogen is liquid nitrogen. First of all, it needs internal pressurization equipment to make nitrogen liquid. In addition, due to the pressurization equipment, the internal pressure will be high, which requires the strong pressure resistance of the material.
Finally, the boiling point of nitrogen is - 195 ℃, and the temperature of liquid nitrogen is very low, which requires its ability to withstand low temperature.
Therefore, ordinary tanks can't store liquid nitrogen. Only liquid nitrogen tanks made of high-strength aviation aluminum can be used. Liquid nitrogen tanks can generally be divided into liquid nitrogen storage tanks and liquid nitrogen transportation tanks.
The liquid nitrogen storage tank is mainly used for static storage of liquid nitrogen in the room, which is not suitable for long-distance transportation under working condition;
In order to meet the transportation conditions, the liquid nitrogen transport tank has made a special shockproof design.
