Liquefied natural gas (LNG) is stored in normal pressure and cryogenic storage tanks.

LNG storage tank pressure testing

Normal pressure cryogenic storage tanks are resistant to low temperatures

Content

Natural gas is recognized as a clean, environmentally friendly and safe energy source. After liquefaction, the volume of natural gas is reduced by about 600 times, which brings great benefits to storage. To store liquefied natural gas (LNG), atmospheric pressure and low-temperature storage tanks are used.
