Minimum Required Head Thickness is expressed in m. No universal acceptance threshold is defined by this calculator.

Worked Example

Verified calculation

Given:

  • External Design Pressure = 100000
  • Knuckle Radius = 0.06
  • Spherical Radius (Crown Radius) = 1.2
  • Material Yield Strength = 250000000
  • Buckling Safety Factor = 2

Expected Result:

  • Minimum Required Head Thickness = 0.004792

Engineering Interpretation:

Under the given input conditions, the calculated result is: Minimum Required Head Thickness = 0.004792 m.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from automatically validated test cases.
