What to do when a drop down listing does not have a specific selection that is normally there?
If specific information was not listed on a drop down listing that would otherwise normally be available means that there may be no library data for that setting per that pipe size. See AutoPIPE help to confirm.
Use one of the following options:
Select NS (Non-Standard) from the drop down listing, and enter the relevant dialog values as needed
Also, be sure to review AutoPIPE help for information on each of the available dialog settings and why other settings are unavailable.
Manually update the Component Library to include new library values based on each pipe size of interest.

Pipe size = 22 inch dia.
Type of valve available was only Ball valve
From the Valve dialog select "Help" button,
> Valve Type hyperlink,
> View Standard Valves in Library hyperlink
> ANSI/ASME Library
> Standard Ball Valve (Side entry)
Note, 22 inch valve library information was available for a ball valve.
However, NO 22 inch valve library information was available for a Gate valve. Thus Gate valve was not an available selection on the valve drop down listing image above.
Pipe size = 100 inch dia.
No Flange Pressure Rating and ANSI Check is greyed out
Why and how to avoid?
Again, see AutoPIPE help for library information available for flanges of that pipe size. Note, there was no library information available for flanges of that pipe size. Thus the only option would be to set the Pressure rating to NS.
The ANSI flange check was greyed out because library information was not available. Please see AutoPIPE help on this setting what to do when this option is greyed out / unchecked.
Note, when using the Flange Check utility be sure to update the ANSI Check tab as needed before analyzing the flange on the Analysis tab.
