LNG 운반선의 LNG 저장탱크용 이미지 For LNG Storage Tanks on LNG Carriers
During liquefied natural gas (LNG) transport, the temperature is −196°C, but rises to +20–30°C after delivery, causing thermal contraction and expansion. Accordingly, the tanks are manufactured from 304L steel, which offers excellent resistance and superior low-temperature toughness due to its nickel content.
