One approximation you could use for torispherical heads (because an accurate number depends on the manufacturer's exact method/procedure) is:

For thickness < 1":

Blank Diameter = OD + OD/42 + 2SF + (2/3)icr

For thickness ≥ 1":

Blank Diameter = OD + OD/24 + 2SF + (2/3)icr + t

Where:

OD = outside diameter of dish, inches

SF = straight-flange length, inches

ICR = inside-corner radius, inches

t = gage thickness, inches

Dear Sir,

What is meant by straight flange length sir.My round tank thickness is 15mm(4.4'').

Will there be any alteration in formula.

Regards,

Dinakar

The straight flange is the straight end portion before the knuckle (section F):

And the approximate formulas I gave will still be applicable, just use the one for thicker gages.
