Shell Thickness Calculation under External Pressure in Pressure Vessels

Shell Thickness Calculation under External Pressure in Pressure Vessels Overview A. Reference: ASME Section VIII Division 1 Paragraph UG-28, Figure UG-28, Figure UG-28.1 ASME Section II Part D Subpart 3, Figure G, Applicable chart, Table 1A, Table Y-1 B. Application: Vacuum condition, tube, others C. Symbol and Definition of external pressure calculation in the shell: Factor A, Factor B D. Minimum Required Data: Design external pressure, Design external temperature, Outside diameter, Length of the shell, Material type E. Step by step calculation 1. Assume t, Calculate L/Do, Do/t 2. Define L/Do 3. Define factor A 4. Define applicable figure and E 5. Define factor B 6. Define Pa using factor B 7. Define Pa using factor A 8. Iterate t until Pa greater than P F. Study cases: 1.5 MPa, 200 deg C, Do 500 mm, L 1000 mm, Material SA 516 Gr.70 Spreadsheet link: http://bit.ly/FNEngineeringFile List of Playlist: Full Video (First Edition) :    • Full Video (First Edition)   Pressure Vessel Basic Design :    • Pressure Vessel Basic Design   Pressure Vessels Series :    • Pressure Vessels Series   Shell and Tube Heat Exchangers :    • Shell and Tube Heat Exchangers   ASME B31.3 :    • ASME B31.3   Design of Material :    • Design of Material   Shell Calculation :    • Shell Calculation   External Pressure Design Calculation :    • External Pressure Design Calculation   Thickness Calculation :    • Thickness Calculation   Welded Joints, Radiograhy, Joint Efficiencies :    • Welded Joints, Radiography, Joint Efficien...   Type of Pressure Design Calculation :    • Types of Pressures Design Calculation   Nozzles, Reinforcement, Flanges, and Fittings :    • Nozzles, Reinforcement, Flanges, and Fitti...   Database Series :    • Database Series   Study Cases :    • Study Cases   Question and Answer :    • Question and Answer   Tools Riset Keyword: https://www.tubebuddy.com/titof (affiliate) ** Affiliate disclaimer: some of the above links may be affiliate links, which may generate us a sales commission
