  Let me introduce you to the characteristics of LNG liquid vacuum storage tanks

  Generally, LNG is stored at -162 degrees. In order to ensure the safety of LNG storage tanks, the following elements need to be considered when selecting the metal materials for manufacturing cryogenic storage tanks:

  The strength in the range of normal temperature to -196 degrees, and has sufficient toughness and plasticity in the temperature range of use, so as not to cause brittle failure.

  Stable metallographic structure, good processability and weldability, low price, easy to buy

  Physical properties suitable for low temperature requirements

  In the cryogenic tank, LNG is in a boiling state, it is close to the boiling state, external heat invades into the gasification and the pressure is extremely high, the safety valve opens or causes greater damage.

  Characteristic requirements of LNG liquid vacuum storage tank:

  1) Strong low temperature resistance:

  The boiling point of liquefied natural gas under normal pressure is -162 degrees. Therefore, LNG requires the storage tank to have good low temperature resistance and excellent cold storage performance.

  2) High safety requirements:

  Since the storage tank contains cryogenic liquid, once an accident occurs in the LNG storage tank, the refrigerated liquid will evaporate in a large amount and become an explosive mixture in the atmosphere. Therefore, the tank requires a double-walled structure and the closed concept is used as the first tank. When the body leaks, the second layer box can completely seal the leaked liquid and vaporized gas to ensure the safety of storage.

  3) Good seismic performance:

  The seismic requirements of general buildings are that they will not rupture and collapse under specified seismic loads. In order to ensure the safety of LNG storage tanks under accidental loads, the storage tanks must have good seismic performance to prevent damage to the tank under a given seismic intensity .

  4) Strict construction requirements:

  Welding must be inspected by 100% magnetic powder, cold insulation materials must be strictly selected, and the specified procedures must be followed during the construction process.

  At present, the material suitable for the construction of low-temperature storage tanks is mainly 9Ni steel. The inner tanks of small and medium-sized LNG storage tanks are made of austenitic stainless steel and are large and extra-large.

  Okay, the LNG liquid vacuum storage tank manufacturer is introduced here. If you have any questions, please leave a message!

Process analysis of LNG vaporization station!

Process analysis of LNG vaporization station!

Process flow of LNG vaporization station. The LNG transported by the tanker is turned on at the unloading platform of the gasification station to pressurize the tanker with its own booster. The pressure difference between the LNG tanker and the storage tank in the station is formed, which plays a role in the pressure difference. Next, the LNG is fed into the low-temperature storage tank of the gasification station for storage through the unloading hose. The low-temperature storage tank in the station makes the pressure of the storage tank reach the value through the storage tank booster, and the LNG in the tank enters the LNG vaporizer through the liquid outlet pipe.
