Replacement requirements for cryogenic storage tanks

After cryogenic storage tank is filled with liquid, the internal pressure is generally maintained at about 0.25~0.35MPa.

Content

At the same time, open the top liquid inlet valve and the bottom liquid inlet valve of the low-temperature storage tank, slowly open the top liquid inlet valve of the tanker, and use the low-temperature gas in the tanker to pre-cool the low-temperature storage tank for 1 to 2 minutes. During this period, the manual vent valve should always be opened to ensure that the nitrogen in the cryogenic storage tank can be completely eliminated during replacement.
