Liquid filling

After pre-cooling, close the bottom liquid inlet valve of the cryogenic storage tank and the top liquid inlet valve of the tanker, and slowly open the bottom of the tanker.

The low-temperature liquid slowly enters the low-temperature storage tank from the top liquid inlet valve of the low-temperature storage tank. The liquid must be filled slowly to avoid damage to the low-temperature storage tank due to rapid cooling. During the initial filling period, the pressure in the cryogenic storage tank will rise sharply. At this time, the size of the manual vent valve should be adjusted to ensure that the pressure in the cryogenic storage tank is about 0.1MPa lower than the tanker pressure.

LNG storage tanks and pipes are made of austenitic stainless steel. Austenitic stainless steels have excellent low temperature properties. But the linear expansion coefficient is high. under the temperature conditions of liquefied natural gas The shortening rate of stainless steel is about 3/1000, and for the 304L material pipeline, when the working temperature is -162 degrees, the 100 m pipeline can be shortened about 300 mm.
