Common problems and solutions of cryogenic storage tanks

Cryogenic storage tank is a very important gas storage device, which plays a very important role in industry. The storage tank is a very strict product, but even so, it is difficult to guarantee that it will cause problems. After a long period of use, some problems such as lng storage tanks and liquid oxygen storage tanks will occur. We must find and solve the problems in time. Let's take a look at what happens to cryogenic storage tanks, what should I do if something goes wrong?

1. The evaporation capacity of the cryogenic tank becomes larger and the vacuum degree becomes smaller. It may be the cause of deflation of pearlite. Pearlescent sand has a fixed particle size and temperature requirement when filling. When the particle size and temperature of pearlite are not suitable, after a period of operation, the pearlite will release water vapor, which will reduce the vacuum and increase the evaporation.

2. "Sweating" on the top of the outer cylinder of the cryogenic storage tank. It may be caused by the collection of pearlescent sand in the lower part. Because after being put into use for a period of time, the pearlite sand sinks to form a space on the top of the container, and part of the heat insulation effect is significantly reduced, causing the container to run cold. In this case, if the amount of evaporation is large, the top of the jacket outer cylinder can be dug up to add pearlite sand. 3. There is a significant large area of "sweating" and "frosting" outside the storage tank. It may be caused by leakage of the pipeline of the storage tank interlayer, unfilled pearlite or other reasons that damage the vacuum of the interlayer. This requires inspection and correction, or leak detection, or to fill the pearlite sand, and can also be evacuated again.
