Maintenance method of low temperature storage tank

Cryogenic storage tanks are important equipment for storing energy. This equipment is widely used and 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 pressure vessels. The specific maintenance methods are briefly introduced below for everyone.

Maintenance method of low temperature storage tank
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. Pay attention to handle the liquid nitrogen tank gently to prevent collision and squeeze, and lift it up when it cannot be dragged on the ground. When not in use, the liquid nitrogen tank should be stored in a dry, well-ventilated room to prevent wetting.

2. Check the neck plug and the small groove of the neck plug at any time, remove the icing on the neck plug in time, and not place plastic cloth and other materials on the neck plug to increase the blockage and ensure the function of the liquid nitrogen tank. When it is found that the consumption of liquid nitrogen is too fast or there are water droplets or hoarfrost 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 low-temperature liquid nitrogen storage tank must be marked, and the handling must be stable, accurate, and fast.

3. In order to prevent corrosion of the tank wall, the inner cavity of the liquid nitrogen cryogenic storage tank needs to be cleaned once a year. Also pay attention to the low-temperature storage tank to minimize transportation, and reduce the number of times to open the liquid nitrogen tank. If it needs to be transported, it is necessary to fix the pressure vessel on the carriage with a rope and keep the liquid nitrogen tank upright. Prevent falls, overturns, lying down, and try to prevent severe vibrations. The advantages of cryogenic storage tanks
1. Light weight and high strength
This kind of 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 it has close tensile strength. The tensile strength of this material The strength exceeds the tensile strength of carbon steel, and its strength can be the same as that of alloy steel. It is needed in various fields. It is needed in the aviation industry, in rocket industry, in spacecraft, and in 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.

2. Has good corrosion resistance
Cryogenic storage tanks are corrosion-resistant materials with good performance. This material has good resistance. The pressure vessel using this material can resist the atmosphere, water, acid, alkali, and salt corrosion, and it can also resist a variety of Oils and solvents, this kind of low temperature storage tanks are widely used, and this kind of equipment is used in all aspects of chemical corrosion protection. This kind of storage tank is replacing the use of carbon steel storage equipment and non-ferrous metal storage equipment.
