Steam Pipe Return Replacement

in THE MAIN WALL
Is it OK to replace about 100 ft of 1-1/4" iron pipe with 1" copper as a return on a steam system in the floor on a slab (no basement)?

    Condensate return

    No,I would not recommend it. I would replace with schedule 80 1-1/4" welded pipe.

    to run the new pipe in the slab?

    the better job

    might as well go the extra mile & use stainless.

    If below the water line

    Type L copper should be fine, with the appropriate flushing fittings as you would do anyway. I would stay away from Type M and if I could find Type K, that would be better.

    No argument against stainless though! Heck, why not. It would be interesting to see what Fe deposition does to it at least. Orbital welding would be a plus, just for fun! OK, kidding...

    But at my heart, I agree with Joe Bertoldi, Schedule 80 steel is a long-lasting traditional approach. I take it that you fully understand that copper above the waterline in a steam system is asking for trouble.
