LNG horizontal low-temperature storage tanks (vacuum powder insulation) typically store LNG at -162°C, where the properties of metallic materials undergo significant changes compared to room temperature. For the manufacturing of horizontal low-temperature storage tanks (vacuum powder insulation) for LNG, the following factors must be considered when selecting the materials:
Strength within the range of room temperature to -196°C (design temperature).
② Exhibits sufficient toughness and ductility within the operating temperature range to prevent brittle failure.
③ Stable metallurgical structure.
④ Excellent workability and weldability.
⑤ Affordable and easily sourced.
⑥ Physical properties suitable for low-temperature requirements.
