The LNG storage tank

Liquid oxygen storage tank is mainly used for cryogenic liquid storage of liquid oxygen, liquid nitrogen, liquid argon and carbon dioxide. One cubic metre of liquid can replace 130 gas cylinders.

Cryogenic liquid storage tank application

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.
