An important means to ensure the safety of cryogenic storage tanks: maintenance

The cryogenic liquid storage tank has a density between 1, 5 and 2, and its density is one-fourth to one-fifth of the density of carbon steel, but the tensile strength of this material exceeds that of carbon steel. Strength, its strength can be the same -as that of alloy steel. It is needed in various fields. It is needed in aviation, rockets, spacecraft, and high-pressure vessels. This kind of equipment is needed in the application equipment of products that need to reduce their own weight. This kind of storage equipment has good characteristics. The effect of use.
 
Cryogenic storage tanks are important equipment for storing energy. This equipment is widely used and is used in many fields. Therefore, the role of storage tanks is recognized by everyone. If users and friends want to make the cryogenic storage tank give full play to its value during use, it is necessary to do regular maintenance work. This is one of the important means to ensure the safety of the storage tank. The specific maintenance methods are briefly introduced below for everyone.
 
1. The cryogenic storage tank should be pre-cooled with a small amount of liquid nitrogen before use. When the temperature in the tank reaches the temperature of liquid nitrogen, fill the liquid nitrogen tank with liquid nitrogen. Be careful to handle the liquid nitrogen tank gently to prevent collision and squeeze, and lift it up when it cannot be dra   gged on the ground. When not in use, the liquid nitrogen tank should be stored in a dry, well-ventilated room to prevent moisture. 2. Check the neck plug and the small grooves of the neck plug at any time, remove the icing on the neck plug in time, and no plastic cloth or other materials can be placed on the neck plug to increase the blockade and ensure the use of the liquid nitrogen tank. When it is found that the consumption of liquid nitrogen is too fast or there are water droplets or hoar frost near the neck of the liquid nitrogen tank, it means that the insulation function of the tank is out of adjustment and the liquid nitrogen cannot be retained. The specimens placed in the liquid nitrogen tank must be marked, and the picking and placing must be stable, accurate and fast.
 
3. In order to prevent corrosion of the tank wall, the inner cavity of the liquid nitrogen tank needs to be cleaned once a year. Also pay attention to the cryogenic storage tank to minimize transportation, and reduce the number of times to open the liquid nitrogen tank. If it needs to be transported, it needs to be fixed on the car box with a rope to keep the liquid nitrogen tank upright. Prevent falling, overturning, lying down, and try to prevent severe vibrations.
