Materials for Large Spherical Tanks for LNG Transport and
Low-Temperature Storage Tanks

Picture of Aluminum Alloy Plates for Moss LNG Tank

Liquefied natural gas (LNG), which is transported by ship at temperatures of minus 162°C, is considered a clean energy source. The world’s largest aluminum plates are widely used for LNG storage tanks. These materials must be resistant to becoming brittle at low temperatures and be lightweight, corrosion- resistant and workable to ensure safety during ocean transport.

Features

  • 5083 alloy has superior strength at low temperatures.
  • They can be produced at maximum sizes of 4 m wide by 16 m long.
  • Irregular shapes, such as trapezoids and rhombuses, are available.
  • We have received plant certification by a classification society (Nippon Kaiji Kyokai) for superior production quality.
  • Plates of other shipping register qualities are also available, such as DNV, LR and ABS.

Applications and Typical Size

  • Large spherical tanks for LNG transport
  • Low-temperature storage tanks
