The Pressure Vessel Defined

Pressure vessel refers to a closed device that contains gas or liquid and carries a certain pressure. In order to implement scientific management and safety supervision and inspection more effectively, my country's "Pressure Vessel Safety Supervision Regulations" divides pressure vessels into three categories according to working pressure, medium hazards and their role in production. And for each type of pressure vessel in the design, manufacturing process, as well as inspection items, content and methods have made different regulations.
