Swage transition nozzle for air cooler

[aard]

I want to know if I can find this swage (See attachement) in any Asme Standard. In B16.9 doesn't appears. I want to order this item but before order it I want to know if there is a standard for it or other name.

These are not standard items. They are custom made for each individual situation.
