Pressure vessel (y ā l ì r ó ng q ì), English: pressure vessel, refers to a closed equipment that contains gas or liquid and carries a certain pressure. In order to implement scientific management and safety supervision more effectively, China's "Pressure Vessel Safety Supervision Regulations" classify pressure vessels into three categories based on work pressure, medium hazard, and their role in production.
A pressure vessel is a sealed container that can withstand pressure. Pressure vessels have a wide range of applications and play an important role in many sectors such as industry, civilian use, military industry, as well as in many fields of scientific research. Among them, pressure vessels are most commonly used in the chemical and petrochemical industries, with pressure vessels used only in the petrochemical industry accounting for about 50% of the total number of pressure vessels. Pressure vessels are mainly used in the chemical and petrochemical industries for processes such as heat and mass transfer, reactions, as well as for storing and transporting gases under pressure 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 for refrigeration compressors (coolers, buffers, oil-water separators, gas storage tanks, evaporators, liquid coolant storage tanks, etc.) are all pressure vessels.
Based on the chemical composition of stainless steel, different types and contents of strengthening elements are added to increase the strength and maintain the toughness of the steel through precipitation hardening process, abbreviated as PH steel. Widely used in industries such as nuclear, aerospace, weapon structural components, pressure vessels, and fasteners.
