    LNG Full Containment Storage Tank

    With the development of LNG industry, LNG storage is becoming more and more large and atmospheric, and the domestic design and manufacturing have reached 50000 M 3, In the coastal area, a single station with a capacity of 250000 m has been built 3、 160000 M 3 LNG atmospheric storage tank is used to receive LNG on board.

    At present, the LNG tanks designed, manufactured and installed in China are mainly 5000m long 3 And 10000m 3, It is widely used in LNG liquefaction plants or LNG peak shaving stations. The amount of LNG produced by industrial tail gas is generally small, and 1000m is commonly used 3 LNG storage tanks on the left and right.
