Minimum requirement of center plate thickness

[Abdul Salam Basheer]

Hi All,

I would like to calculate the minimum thickness for the A36 circular hollow plate to withstand 2400 PSI pressure. Is there any classical formula to calculate the minimum thickness? Thanks

Roark's?

But you probably want to look at those fillet welds too...and...exactly how are they going to be made on the id. of the pipe?

How is the 2400 psi generated? Is this due to fluid pressure, or some sort of mechanical stress?

You might consider this approach which is used on pulleys for belt conveyors.

Formulas in Roark's Formulas for Stress and Strain.
You can approach this in a simplistic way as a plate with simply supported edge.
Or you could calculate edge moments and rotation/deflection in the cylinder as well, which should give you a little better idea of stresses in the welds.
With pressure that high, thickness or weld size may be unreasonable.
If this is part of a pressure vessel, use formulas and detailing from the pressure vessel codes.
