ASME SA516 pressure vessel plates are low-temperature steel plates that complies with ASME (American Society of Mechanical Engineers) standards. The plates have good low temperature toughness and weldability. Therefore, petroleum, chemical, power plants, boilers and other industries are inseparable from its figure.
Operating Steps 1
1. Material selection and procurement: According to the design requirements and engineering specifications, select the appropriate ASME SA516 class (such as Gr.55, Gr.60, Gr.65, Gr.70, etc.). Sourcing materials from reliable suppliers to ensure that the material has qualified chemical composition and mechanical properties. Check the warranty, certificate and inspection report of the materials to ensure that they meet the requirements of the standard.
2. Material inspection and storage: Conduct a comprehensive inspection of the purchased materials, including appearance inspection, size measurement, chemical composition analysis and mechanical property testing. Workers should properly keep qualified materials to avoid moisture, rust and damage.
3. Steel plate cutting and processing: According to the requirements of the drawings, the use of appropriate cutting equipment (such as flame cutting machine, plasma cutting machine, etc.) to cut the steel plate. Workers treat the edges of the cut steel plate to remove burrs and oxide layers. The necessary processing of the steel plate, such as drilling, milling groove, etc., to meet the subsequent assembly requirements.

4. Welding and heat treatment: Select the appropriate welding method and welding material to ensure that the welded joint has sufficient strength and tightness.
Non-destructive testing of welded joints (such as X-ray testing, ultrasonic testing, etc.) to ensure the quality of welding. According to the need, the welded steel plate is heat treated to eliminate the welding stress and improve the microstructure.
5. Quality inspection and acceptance: comprehensive quality inspection of the processed pressure vessel plate, including appearance inspection, dimensional measurement, non-destructive testing, mechanical performance testing, etc. Ensure that the pressure vessel plates meet the design requirements and engineering specifications before acceptance and delivery.
Matters Need Attention
Strictly follow the relevant safety operation procedures to ensure the safety of personnel and equipment.
Regular maintenance and inspection of equipment to ensure that it is in good working order.
Keep the working environment clean and orderly, avoid debris and obstacles affecting the operation.
Nonconforming products are identified, isolated and disposed of to prevent confusion and misuse.
In summary, the operation of ASME SA516 pressure vessel plates requires certain steps and precautions to ensure product quality and safety. In actual operation, it should be properly adjusted and optimized according to the specific situation to meet the engineering needs.
