In the middle of the floor is a 2inch steam pipe that needs to move closer to the wall , can the pipe be cut and moved and reattached with some kind of clamp of some sought or does it have to be move with thread pipe as it is now but with shorter length of pipes

It must be threaded pipe. No rubber boots, Etc...
