Low temperature container properties and characteristics of industrial nitrogen at very low temperatures by pressurized nitrogen is a colorless liquid, then the liquid nitrogen cryogenic vessel temperature is very low, then the cylinder containing, then put into the cylinder under normal temperature, the ambient temperature rises, the temperature of liquid nitrogen in the bottle containing elevated into room temperature then, the liquid nitrogen in the bottle pressure will become higher.
But in actual circumstances, either the cylinder insulation effect is very good, or there is pressure relief safety valve, or the opening of the cylinder opening time is very short. The temperature in the cylinder can not reach normal temperature.
The industrial use of liquid nitrogen at very low temperatures by pressurized nitrogen is a colorless liquid, then the liquid nitrogen temperature is very low, then the cylinder containing, then put into the cylinder under normal temperature, low temperature storage tank due to environmental temperature is:
The bottle containing liquid nitrogen will change, which is vaporized by liquid nitrogen into gaseous nitrogen, the cylinder pressure increases, the inside temperature is the temperature of liquid nitrogen and nitrogen coexist, generally -196 degrees C, absorb external heat the temperature continues to rise, the pressure continues to rise, the pressure relief valve will play a role of pressure relief. If not only temperature, pressure relief, pressure in the cylinder of liquid nitrogen will be very high it, causing pressure vessel explosion.
Liquid nitrogen tank insulation effect is very good, liquid nitrogen in it can be stored for 1 months, not vaporized.
