Pressure tanks are used in industrial settings such as nuclear reactors and mining. Aside from that, they are utilized in everyday tasks such as heating water and distillation. They are completely safe for storing liquid gasses. It stores water and provides water under pressure when the pump is not running. It builds up a reserve supply of water so the pump starts and stops less often, prolonging the life of the pump. In addition, it provides a reserve supply of water for use during times of high demand.
Pressure Vessels are containers that are designed to hold liquids, vapors, or gases at high pressures, usually above 15 psig. Examples of common pressure vessels used in the petroleum refining and chemical processing industries include but are not limited to, storage tanks, boilers, and heat exchangers.
