ASME pressure vessels are widely used in the fields of petroleum, chemicals, rubber, pesticides, dyes, medicine and food. They are pressure vessels used to complete vulcanization, nitration, hydrogenation, hydrocarbonization, polymerization, condensation and other processes. Its structure generally consists of a kettle body, a transmission device, a stirring device, a heating device, a cooling device, a sealing device, a support, etc. Agitators include anchor type, frame type, paddle type, turbine type, scraper type, and combined type. Heating and cooling can use jackets, half pipes, coils, honeycomb panels and other structures. Heating methods include: steam, electric heating, and thermal oil. Supports include leg-type, ear-type and support-type supports to meet the process needs of different working environments such as acid resistance, high temperature resistance, wear resistance and corrosion resistance.
In ASME (American Society of Mechanical Engineers), pressure vessel regulations are mainly defined by the ASME Boiler and Pressure Vessel Code (ASME Boiler and Pressure Vessel Code). According to this specification, a pressure vessel refers to a container used to store or transport gas, liquid or steam containing internal pressure.
The ASME code classifies pressure vessels based on their design working pressure (Design Pressure). According to the definition of the ASME Code, a vessel can be classified as a pressure vessel when its design working pressure exceeds 15 psi (pounds per square inch, approximately 1.03 bar).
The ASME Code divides pressure vessels into different categories and divisions and provides detailed requirements and guidelines for their design, manufacture, inspection and use. These requirements include container material selection, construction, strength calculation, welding requirements, non-destructive testing, pressure testing, etc. to ensure the safety and reliability of pressure vessels.
High strength and durability: ASME pressure vessels are made of stainless steel material, which has high strength and corrosion resistance. They are able to withstand working environments under high pressure and extreme conditions, ensuring stable and safe operation of industrial processes.
Diverse applications: ASME pressure vessels are widely used in various industries. They are used to store and transport gases, liquids or chemicals and provide essential products and services to the petroleum, chemical, energy, pharmaceutical and other industries. Whether storing liquefied gas, supplying industrial gases, or serving as nuclear reactor vessels in nuclear power plants, pressure vessels play an important role.
Space efficiency and energy conservation: ASME pressure vessels are typically designed to be compact, allowing efficient use of space. Compared with traditional storage methods, such as bulk storage, pressure vessels can save a lot of space and improve storage efficiency. In addition, ASME pressure vessels can reduce energy consumption and efficiently utilize heat energy.
