can somebody help with tis?

Doing some renovation we need to move a pipe. The pipe was run thru a wall from apartment below us to room above but wall isn't there anymore.
Pipe is 2 inch but that pipe is old rigid black pipe(I think is steel and actual size is 1 7/8 ). we need to cut it from the bottom and top to reroute it.
Is anybody knows any change overs from that old black pipe to new fittings?
I will try to make some pictures.

I an not sure but that black iron should be the same as a galvanized pipe. A threadless connector or coupling may work or you will need to thread the ends.

Be forewarned: black iron pipe was used mostly for two things; gas and waste drains. Either one may affect your decision to be cutting anything without a VERY thorough investigation!

Is not that simple. If it was, I will not ask.
This is in New York City. Old building have that metal conduit.

There's millions of feet of black pipe in NYC used as electrical conduit much of it embedded in pour concrete decks. A simple thread-less fitting for RMC should work as Dennis suggested.
