Steam Riser

in THE MAIN WALL
perhaps an easy question: A steam "riser" is a supply line that continues from floor to ceiling, continuing up to supply additional stories, such as in an apartment building. What is the name for a steam supply line that does not continue up to higher stories? is just a stub on the floor that is there to supply a single radiator? thanks

    Still a riser.

    I'd call it a riser to the first floor.

    branch

    a branch line would be the correct piping term

    and if that branch turns vertical?

    what do you call that piece that sits vertical? to me its still a riser cause it has to have a different name cause it very likely will be a different size than the runout or branch..dont you think?

    those damn risers

    usually a riser is the pipe that " rises " from one storey to the next. take-offs from tee's off the riser are called branches that supply all the various piping on one floor.a take-off from a horizontal overhead main is considered a branch even though it penetrates the ceiling.in my world anything other type references would be too confusing especially when confering with other mechanics. if i would tell one of my men to cut a tee into a riser i want to be sure he understands the procedure without my being present on the jobsite. wow, this is getting way too technical. lol its only rock n roll
