Air Storage Tank (pressure vessel), also known as a compressed air storage tank, is a pressure vessel specifically designed for storing compressed air. It is mainly used for gas buffering and plays a role in stabilizing system pressure, avoiding the frequent loading and unloading of air compressors, and removing most of the liquid water. The air storage tank is typically composed of parts and components such as the cylinder body, end caps, flanges, pipe connections, sealing elements, and supports. Additionally, it is equipped with accessories such as safety valves, pressure gauges, and drain valves to complete different production process functions.
