A pressure vessel is a sealed container that can withstand pressure.The use of pressure vessels is universal, and they play an important role in many aspects of industry, civilian use, military industry, and scientific research.Among them, pressure vessels commonly used in the chemical and petrochemical industries account for 50%of the total number of pressure vessels used only in the petrochemical industry.
Pressure vessels are mainly used in the fields of chemical and petrochemical industries for processes such as heat transfer, mass transfer, and reaction, as well as for storing and transporting pressurized gases or liquefied gases;It is also widely used in other industrial and civilian fields, such as air compressors.All types of specialized compressors and auxiliary equipment of refrigeration compressors(coolers, buffers, oil-water separators, gas storage tanks, evaporators, liquid coolant storage tanks, etc.)are all pressure vessels.
