Technical Requirements
1.With high safety and sealing, it can ensure the safety of storage and prevent accidents, widely used in petrochemical and other fields. 
2.The primary and secondary container are both flat-bottomed and cylindrical metal storage tanks, and the primary container top is deck type. It is suspended from the vault support structure of the secondary container through a boom. The top of the secondary container is a spherical arch, and the top support structure is a ribbed ring grid. The foundation of the LNG storage tank adopts a concrete elevated pier structure.
3.The following are safety measures to prevent overpressure:
1)Recycle the evaporated gas from the tank via the BOG pipe; 
2)Discharge the gas from the tank to a low-pressure flare through the vent line; 
3) The exhalation relief valve actuates to vent gas from the tank to the low-pressure flare;
