The vacuum degree standard of LNG storage tanks
The vacuum degree standard of LNG storage tanks mainly depends on the type of storage tank and the conditions of use.
The vacuum degree standard of LNG storage tanks mainly depends on the type of storage tank and the conditions of use.
For high vacuum storage tanks, the vacuum degree should be less than or equal to 0.1Pa.
The vacuum degree standard of pearl sand storage tanks is less than or equal to 5Pa.
In general, the vacuum degree of LNG storage tanks should be measured once a year, and the specific frequency can be determined according to the on-site use.
In addition, for LNG cryogenic liquid storage tanks, the vacuum degree of the container interlayer should be less than 65Pa at normal temperature and less than 10Pa under low temperature conditions.
