LNG storage tanks are mainly used for emergency storage. At present, with the shortage of energy, the adjustment of energy structure and the increase of environmental protection pressure, the demand for natural gas is gradually increasing, and the inner tank materials of lng storage tanks are also paid more and more attention.

The liquefaction temperature of natural gas is -162°C, and the volume of liquefied natural gas (LNG for short) is 1/600 of the gaseous state, which makes the material requirements for LNG storage tanks higher.

Most of the aluminum alloys used in LNG storage tanks are 5 series 5083 aluminum sheet. The reason why 5083 aluminum sheet can "take this responsibility" is mainly because 5083 aluminum sheet belong to AL-Mg series alloys, with low density, high strength, good fatigue performance and welding performance. Good resistance to marine atmospheric corrosion. The tensile strength is between 290-345Mpa and the yield strength is between 145-283Mpa. 5083 aluminum plate is used in occasions requiring high corrosion resistance, good weldability and medium strength, such as ships and automobiles, and can also be used in pressure vessels, refrigeration installations, TV towers, drilling equipment, transportation equipment that require strict fire protection Wait.
