The cryogenic storage tank adopts a unique vacuuming process

Content

(7) The sand loading adopts the process of negative pressure filling and positive pressure compaction to ensure the uniformity of the interlayer pearlescent sand. The compaction process is used to maximize the filling amount of pearlescent sand to ensure the cold preservation effect of the interlayer.

(8) The unique vacuuming process is adopted, which greatly shortens the evacuation time of the inner tank and the interlayer, ensuring that the vacuum degree of the interlayer is better than the requirements of national standards. Ensure that the vacuum of the storage tank does not require reprocessing within 3 to 5 years.
