For semi-ellipsoidal dished ends (see Lynlynch's post) volume = pi*Di2*a/6. a is the internal height, from the dotted line (the tan line). The picture is a bit confusing as most of the heights are labelled h1.

It won't be exactly the same for torispherical, but I'd have thought plenty near enough in practice. If you haven't got the height, need to calculate it from the other dimensions, with a bit of schoolboy geometry!

If there is a formula for torispherical end volume, I'm not aware of it.

Cheers.........Codey

Dished-Ends
Torispherical heads
  • Shape (Applicable standard or dishing radius r1 and knuckle radius r2)
  • Diameter Da or Di
  • Minimum wall thickness after formings
  • Straight flange h1
  • Weld-edge preparation
Elliptical heads
  • Shape ( applicable standard or axis ratio b : a )
  • Diameter Da or Di
  • Minimum wall thickness after formings
  • Straight flange h1
  • Weld-edge preparation
Flat heads, flanged on
  • Diameter Da or Di
  • Minimum wall thickness after formings
