Liquefied natural gas (LNG) is an important clean energy source. To store LNG, tanks must be able to withstand extreme temperatures and pressures. The boiling point of liquefied natural gas at low temperature and normal pressure is -160°C. LNG chooses a low-temperature and normal-pressure storage method to lower the temperature of the natural gas below the boiling point, so that the operating pressure of the liquid storage tank is slightly higher than normal pressure.

5083 Aluminum sheet plate belongs to the Al-Mg series alloy. The main element is magnesium, and the Mg content can reach between 4.0% and 4.9%. 5083 aluminum sheet plate is a kind of rust-proof aluminum with high strength, good plasticity, strong corrosion resistance, good processability, and light weight. It has become a widely used material for manufacturing low-temperature storage tanks such as LNG storage tanks and LNG ships. 5083 aluminum plates are mainly used in tank top, brackets and other parts of LNG storage tanks. Using aluminum alloy suspended ceilings instead of traditional stainless steel suspended ceilings can effectively reduce construction costs and facilitate construction.

5083-O aluminum sheet plate has high strength at low temperatures, such as LNG temperatures. Cryogenic storage tanks are materials for large spherical tanks used for the transportation and delivery of liquefied natural gas. Cryogenic storage tanks and liquefied natural gas are transported by ships at a temperature of -162 degrees Celsius and are considered a clean energy source. 5083 aluminum plates are widely used in LNG storage tanks. 5083-O aluminum plate resists becoming brittle at low temperatures, is lightweight and corrosion-resistant, and ensure safety during ocean transportation.
