What aspects should be paid attention to when storing cryogenic vacuum pipes?

Cryogenic vacuum piping should not be stored in a sealed room (eg walking in a cold room) as reducing ventilation may not be enough to mitigate against spills and general evaporation.

Adequate ventilation is required when storing liquid nitrogen tanks larger than 30 liters indoors, and additional precautions need to be taken when most of the cryogenic vacuum pipes larger than 30 liters are stored. In these cases should room size; storage conditions: ventilation; and possibly use of low oxygen level alarms.

Only use containers designed for cryogenic liquids, which are materials specifically designed and manufactured to withstand the rapid changes encountered in the extreme temperature differences encountered when using liquid nitrogen. Even so, these special containers should be filled slowly to reduce the internal stress that occurs when the material is cooled.

1) Do not cover or plug the inlet of the cryogenic vacuum pipe;

2) Do not use plugs or other devices that would interfere with venting;

Cryogenic vacuum piping is generally designed to operate with little or no internal pressure. Insufficient exhaust can lead to excessive gas pressures that can damage or explode containers. Regular inspection of equipment. Unrestricted ventilation by snow or frost.
