plumbing repair in attic have to cut long 1" pipe cause cannot get in attic?
Plumbing Repairs November 28th, 2008cutting at joint and is their a union to splice into 1" steel pipe after i cut it
To properly cut and re-thread steel pipe you need a pipe cutter, pipe threader, and pipe deburrer…none of which are cheap. If you know how long a piece you need, have the supply house or home center cut and thread the piece(s) for you. I think Lowes does this for little or no extra cost. If you have a lot of threading to do, try renting the cutter, threader, and de-burrer, plus a pipe vise. [You will also need cutting oil for the threading process.] You then use couplings, not unions, to rejoin the pieces. [Unions are used to join two pipes when you cannot turn one of the pipes because it is already in place.] Use standard forged couplings, not the cheap smooth "merchant" couplings which often come with pipe lengths. Be sure to use high quality "pipe dope" to join the pipe/fittings. It comes in tape or brush on types, depending on your preference, the type of pipe, and what the pipe will carry [water, gas, etc.]

YES. If this is steel pipe you can cut it. What you have to do though is buy a pipe threader. This is like a hand held ratchet that will cut threads into the pipe. Thread the ends you cut and you can put in a union to reconect the pipe.

may be gas pipe if in attic, better let a pro do this on. Normally water pipes are in ground, crawl spaces, or in between floors.

are we talking about a gas line? you can't put a union in an attic because it is not accessible if its a gas line. what they do make is a left right nipple and coupling that will tighten both sides at the same time. if its a water line then yes you can use a union. I hope you have a hand threader to thread the pipe.
