Storage tanks are mainly used for indoor storage of liquid nitrogen, should not be used for long-distance transport in the working state; liquid nitrogen transport tanks to meet the transport conditions, made a special earthquake-proof design. In addition to being stored for standing, it can also be transported under liquid nitrogen conditions, but it should also avoid violent collisions and vibrations. When the liquid nitrogen tank is not in use, it should be rinsed with clean water, drained, blown dry with a blower, and left to stand at room temperature. After the liquid nitrogen in the liquid nitrogen tank is volatilized, the remaining missing material quickly melts and becomes a liquid substance attached to the inner bladder. This will cause corrosion of the aluminum alloy inner liner. If a hollow is formed, the liquid nitrogen tank will be scrapped. Therefore, it is necessary to scrub the can after the liquid nitrogen in the liquid nitrogen tank is exhausted. The Liquid nitrogen tank (liquid nitrogen biological container) Product composition: outer gallbladder, liner, neck pipe, insulation material, suction nozzle, lifting tube and other components.
