LNG tank vacuum pumping

LNG tanks must be purged and precooled with nitrogen before use

Content

At the same time, the jacket (the space between the two layers of containers) is pumped into a high vacuum to form a good insulation system. The design of the outer shell and support system can meet the ability to withstand the relevant external forces generated by the transport vehicle during driving. Commonly used LNG cylinders include 175L, 195L, 210L, 375L, 410L, and 495L. It is stipulated that the volume of a single 175L cylinder in a cylinder group gasification station should not be greater than 410L.
