5754 aluminum alloy is a popular choice for cryogenic applications, including LNG storage tanks, due to its excellent low-temperature toughness, weldability, and corrosion resistance.
Why 5754 Aluminum for LNG Tanks?
Cryogenic Toughness: Retains strength and ductility at temperatures as low as -196°C , which is crucial for LNG storage.
Corrosion Resistance: Resists stress corrosion cracking and performs well in marine environments .
Weldability: Easily welded using conventional methods without significant loss of properties.
Lightweight: Reduces structural weight compared to steel, improving transport efficiency.
Comparison with Other Aluminum Alloys
5083 Aluminum: More commonly used for LNG tanks due to higher strength, but 5754 offers better formability and corrosion resistance.
6061 Aluminum: Not ideal for cryogenic use due to lower toughness at extreme temperatures.
5052 Aluminum: Similar to 5754 but with slightly lower strength.
5754 Aluminum Applications in LNG Storage
Primary & Secondary Containment: Used in inner tanks and outer shells.
LNG Carrier Tanks: Preferred for membrane-type LNG containment systems.
Pipework & Valves: Used for cryogenic piping due to thermal conductivity and low-temperature performance.
