Regarding the strength calculation of S30403 material
Thread Content
There is a small container: with a diameter of 600 mm, made of material S30403, featuring a design pressure of 8.7 MPa and a design temperature of 70°C. A board thickness of 30 mm was selected, but an error occurred during calculation. What is the reason? As shown in the figure below:
Calculation conditions: Calculation pressure: 8.70 Design temperature: 70.00 Inner diameter of cylinder: 600.00 Corrosion allowance: 0.00 Negative deviation: 0.30 Weld joint factor: 1.00 Material: S30403 Input thickness: 30.00 Calculation results: Stress check: Pass Allowable pressure: 11.32 σt = 92.23 t*Φ = 120.00 Hydrostatic test value: 10.8750 Cylinder stress: 115.29 0.9*ReL: 162.00 Pressure test passed. Note: Reference thickness: 23.00 After calculation, there are no issues at all; you may have entered the wrong values or selected the wrong material type

You have chosen a pipe material, and the maximum thickness of such pipes is 28; therefore, it is indicated that the pipe size exceeds this limit
Thank you to all the teachers for their replies. The reason has been found: it is because of the type of pipe selected, which limits the thickness to 28mm.
