Shell Thickness Calculation under External Pressure in Pressure Vessels

Описание: 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
