Nitrogen heats the outer cylinder of the interlayer vacuum balance of the cryogenic storage tank

What is a dewar tank?

The cryogenic storage tank can heat the inner cylinder

Content

If the vacuum degree does not rise much during evacuation, it should be considered whether the cleanliness of the interlayer is qualified and whether the moisture content of the pearl sand exceeds the standard. At this time, it should be considered to use nitrogen to heat the outer cylinder of the interlayer vacuum balance of the cryogenic storage tank.
