The Plot > Plot Nozzle 
option in the local graphics environment constructs the nozzle plot diagrams of API-650
Appendix P, necessary to determine if a nozzle is overloaded.
Click the down arrow on the Plot Nozzle icon to access several additional functions.
-
Use Plot Nozzle > Select Nozzle for Display to select which nozzle to plot. The number of nozzles you can select in this option depends upon your TANK input. You can add up to 15 nozzles to the TANK input.
-
Use Plot Nozzle > Use "Design" Thickness to display the design thickness on the nozzle plot.
-
Use Plot Nozzle > Use "Test" Thickness to display the test thickness on the nozzle plot.
-
Use Plot Nozzle > Use "User Input" Thickness to display the user input thickness on the nozzle plot.
-
Use Plot Nozzle > Longitudinal to display the nozzle plot from the longitudinal perspective.
-
Use Plot Nozzle > Circumferential to display the nozzle plot from the circumferential perspective.
The resulting nozzle plot shows the interaction point as an asterisk. The location of this point is determined on the plot using the input values of applied piping loads. If piping loads are not specified, the interaction point plots at the origin.
For the nozzle to meet the criteria of API-650 Appendix P, the interaction point
must plot inside the diagram.
The following examples show nozzle plot diagrams from the longitudinal and the circumferential perspectives.
