Indicates that you are supplying reducer data. Select or clear this option by double-clicking Reducer on the Classic Piping Input dialog box.

Specifies the Diameter 2, Thickness 2, and Alpha values at the To node of the reducer. The diameter and wall thickness at the From node of the reducer element are taken from the current piping element data.

CAESAR II constructs a concentric reducer element made of ten pipe cylinders, each of a successively larger or smaller diameter and wall thickness over the element length. CAESAR II calculates SIFs according to the current piping code (for more information, see Code Compliance Considerations) and applies these internally to the Code Stress Calculations. These SIFs are dependent on the slope of the reducer transition (among other code-specific considerations), Alpha. If Alpha is left blank, then the software calculates this value based on the change in pipe diameter over 60% of the element length. If specified, Diameter 2 and Thickness 2 are carried forward when the next pipe element is created as Diameter and Wt/Sch. If not specified, Diameter 2 and Thickness 2 are assumed to be equal to Diameter and Wt/Sch on the following element dialog box.

If there is no value for Alpha is specified on the dialog box, CAESAR II reports the alpha value in the Errors and Warnings dialog box.
