I assume you want to part it non-destructively?

Very much so - it's SS and cost.

If it's stuck together, the best way of unsticking it is to rotate one
part relative to the other by a few degress, rather than trying to
drift it apart. You might be able to grip it to rotate it by using a
strap wrench - intended for unscrewing oil filters.

With the help of a neighbour and penetrating oil we got it to turn and
pulled off - without tools. Couldn't have done it myself in a million
years without damage.
The part of the pipe now exposed was like brand new - still shiny.
