Indicates that you are supplying equipment data. Select or clear this option by double-clicking Nozzle Lmt Check on the Classic Piping Input dialog box.

Equipment nozzle evaluation is one of the most important tasks in analyzing a piping system. The various nozzle loads, when subjected to the operating criteria of the piping system, must be less than their associated allowable loads. Verification of the nozzle loads is a time-consuming task, which cannot be performed until the pipe stress requirements are met.

CAESAR II enables you to define overall nozzle limits. This permits CAESAR II to perform a first pass screening. Actual detailed nozzle evaluation can then be focused on those nozzles that fail this initial screening.

Example

To illustrate this procedure, consider the limits defined for a nozzle displayed below:

The data above specifies the nozzle limits and how the resulting loads (from the analysis) are compared to the limits. After the analysis has been performed and the results are available, you can select the specific load case the nozzle must be evaluated against as well as the Nozzle Check report. For more information on the Nozzle Check report see the Equipment Report.

Nozzle Limit Check is a first pass at qualifying the equipment nozzles. This is a simple check based on the limits defined on this dialog box. This screening is not a substitute for the more rigorous checks of the actual equipment standards.
