A pressure vessel is a closed container that can withstand pressure.
The use of pressure vessels is extremely extensive, and it has an important position and role in many sectors such as industry, civil use, military industry, and many fields of scientific research.
Among them, the chemical industry and petrochemical industry are the most used, and the pressure vessels used in the petrochemical industry alone account for about 50% of the total number of pressure vessels.
In the chemical and petrochemical fields, pressure vessels are mainly used for heat transfer, mass transfer, reaction and other processes, as well as storage and transportation of pressurized gases or liquefied gases; they are also widely used in other industrial and civil fields, such as air compression machine.
All kinds of special compressors and auxiliary equipment of refrigeration compressors (coolers, buffers, oil-water separators, gas storage tanks, evaporators, liquid coolant storage tanks, etc.) are pressure vessels.
