Flange forgings of petrochemical ring are important equipment in petrochemical industry, and their strength design is directly related to the safety and stability of the equipment. This paper will introduce the strength design process of flange forgings of petrochemical ring parts, in order to provide reference for relevant people.
Strength design process
Determine the design objectives: according to the use requirements and process conditions of the equipment, determine the design objectives of the flange forging, including working pressure, working temperature, material selection, etc.
Establish mathematical model: According to the design goal, establish the mathematical model of flange forgings, including geometric shape, size parameters, etc.
Force analysis: According to the actual working conditions, the force analysis of flange forgings, including the influence of working pressure, working temperature and other factors.
Check calculation: According to the result of force analysis, strength check calculation, including tensile strength, compressive strength, bending strength, etc.
Material selection: According to the check calculation results, select the appropriate material to ensure the strength and stability of the flange forging.
Process design: According to material selection and design objectives, process design, including heating, cooling, heat treatment and other processes.
Processing and manufacturing: According to the process design requirements, processing and manufacturing to ensure the accuracy and quality of flange forgings.
Inspection and testing: Inspection and testing of flange forgings completed by processing and manufacturing, including dimensional accuracy, surface quality, hardness testing, etc.
Delivery: Delivery of qualified flange forgings to ensure the safety and stability of equipment.
In the strength design, the actual working conditions and use requirements should be fully considered to ensure the rationality and reliability of the design.
Appropriate calculation methods and tools should be used to ensure the accuracy and reliability of the calculation when the force analysis and checking calculation are carried out.
When selecting materials, factors such as mechanical properties, chemical composition and process properties of materials should be considered to ensure the quality and stability of materials.
In the process design and manufacturing, the relevant standards and regulations should be followed to ensure the accuracy and reliability of the process.
In the inspection test, appropriate detection methods and tools should be used to ensure the accuracy and reliability of the test.
Before delivery, flange forgings should be fully inspected and tested to ensure that they meet the relevant standards and requirements.
The strength design of flange forgings of petrochemical ring is one of the important links to ensure its safety and stability. The strength and stability of flange forgings can be ensured effectively through comprehensive evaluation and design by determining design objectives, establishing mathematical models, force analysis, checking calculation, material selection, process design, processing and manufacturing, inspection and testing. At the same time, attention should be paid to the relevant standards and requirements in the design and manufacturing process to ensure the rationality and reliability of the design.
