The Essential Attributes of Liquefied Gas Tanks
Liquefied gas tanks are pressure vessels specifically designed for storing liquefied gases, falling under the category of special equipment. Through internal pressurization and insulation, they convert gas into a liquid state for storage, reducing volume by hundreds of times. Commonly used for storing liquefied petroleum gas (LPG), liquid nitrogen, and other media, they possess characteristics such as high pressure resistance and leak-proof design.
Unique Working Principle
Phase Change Control: Liquefies the gas through cooling or pressurization.
Double-Layer Structure: The inner liner is pressure-bearing, while the outer shell is insulated.
Safety Design: Equipped with pressure relief valves, level gauges, and other devices.
Material Selection: Utilizes special steel with good low-temperature toughness.
Places in Daily Life and Industry
From gas cylinders in restaurants to liquid oxygen storage tanks in hospitals, liquefied gas tanks are ubiquitous. In the industrial sector, they are commonly used for raw material storage in chemical plants, while in the civilian sector, they are mostly used for household gas supply. Different scenarios have different requirements for tank volume and pressure rating, but the core function remains the safe and efficient storage of liquefied media.
