How to Cut/thread recessed pipe??

I have a potential project where we need to cut off an existing 2 -pipe vapor supply and offset it about 12 inches below the floor.  There is no access from below.  Is there some tool or way to cut and thread this supply from above so I can fit it with an elbow.  I have the typical rachet style manual threaders and cutter.

    if the opening in the floor is big enough, this should work well. You can hold back with a standard pipe wrench when the Pipecat is running.

  • Strange circumstance Dave,

    not sure how big the hole in the floor is, or what pipe size you need to thread,,, but you`ll likely have to do-it the hard way(using ratchet dies & holding the pipe with a wrench), perhaps try a different cutting fluid(Rapid Tap) to make the job go easier?
  • I guess....

    there is nothing around that would drive a threading die like a drill driving a bit.  Sure could come in handy.  I need to thread 3/4 inch.

    Old dies

    If you can find some old the old hex or square dies and a socket to fit you could use and extension on a ratchet. If you have a hole big enough to ratchet regular dies 3/4 shouldn't have much problem. The other option would be a Dressler fitting.

    another thought

    If you have an older set that you don't mind ruining you could weld to a socket or pipe and then weld a plate and nut on the other end to you can turn it with a socket. By recessed I take you mean it is set back from the opening.

    Yes there is, BP

    The Pipecat! The smaller one is the 600 and the larger is the 700. It is a hand-held, motor-driven threader that uses ordinary dies, and can also drive a 400 threader with an adapter.

  • A little confusion, I think....

    The power drives (cat) work at 90 degrees to the pipe, I was thinking of something that would be in line with the pipe...like the idea further down that could be turned like a socket Or like a drill driving a drill bit.  If nothing is made this way, I may just get a socket welded to the threading die and use any extension and socket wrench to turn it from above.

    can you....

    Can you take the nipple out and put in a smaller one?

    Just a thought, sight unseen.
