I may not be able to help you 100% . But I throw some light on your problem.

There is empirical formula for blank diameter

F x d +2 X SF

Where F factor depending on type of head

d inside diameter of head

SF Straight portion length

Now F factor I believe that 1.3 for ellipsoidal head and 1.1 for torispherical head.

For elliptical heads, the approximate blank dia. d shall be:

d = 1.2 (Do - t) + 1.5 SF + 30 mm

[From catalogue of J Bown & Co., England, www.jbown.com]

where, d = Approximate blank diam., mm Do = Head outside dia., mm

t = Plate thickness (or min.), mm

SF = Straight flange height, mm
