[OpenSCAD] Stumped on a shape

I'm trying to build a model which has a small and large pipe merging snd
the join has a flange. With a pipe into a flat surface it's easy enough
as the flange can be modelled by cutting a circle out of a square and
then rotate extruding it.

With a join of two curved pipes however the flange follows a vastly more
complicated path and continually changes shape and size

The effect I'm trying to get is something like the funnel and dome on this
