What Are Gas Tanks?
Gas tanks are containers designed for storing gases, such as fuel or industrial gases. There are two main types: atmospheric pressure tanks that store gases at normal atmospheric pressure, and high-pressure tanks that store gases under higher pressure than atmospheric pressure. High-pressure tanks are often spherical to evenly distribute the internal pressure.
Atmospheric pressure tanks have variable volumes to accommodate changes in gas volume without altering internal pressure. These include dry tanks, with internal partitions moving like pistons to adjust to gas volume changes, and wet tanks, with gas chambers floating in water to move up and down. Wet tanks are highly gas-tight but unsuitable for water-soluble gases due to moisture ingress risks.
For city gas storage, high-pressure tanks are increasingly used. These tanks, with large capacities, adapt to gas quantity changes based on pressure fluctuations.
