Result Interpretation

ASME VIII Div 1 Nozzle Reinforcement Area Requirement (UG-37) calculator computes Required reinforcement area in m^2 using the defined engineering formula and the input values provided. Required reinforcement area is expressed in m^2. No universal acceptance threshold is defined by this calculator.

Worked Example

Verified calculation

Given:

  • Nozzle inside diameter = 0.1
  • Required shell thickness per UG-27 = 0.015
  • Actual shell thickness = 0.02
  • Nozzle wall thickness = 0.012
  • Strength reduction factor for shell = 1
  • Strength reduction factor for nozzle = 1

Expected Result:

  • Required reinforcement area = 0.00186

Engineering Interpretation:

Under the given input conditions, the calculated result is: Required reinforcement area = 0.00186 m^2.

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

Formula / Method

required reinforcement area = (nozzle inside diameter * required shell thickness per ug-27) + (2 * required shell thickness per ug-27 * actual shell thickness * (1 - strength reduction factor for shell)) + (2 * nozzle wall thickness * required shell thickness per ug-27 * strength reduction factor for nozzle)
