I worked on a light commercial installation recently and worked on threaded steel pipes for the first time.
How do you break into it? One length of pipe with joints at either end need to rotate in opposite direction at each end to get undone!
I was lucky in that there was a sort of coupling joint on a short pipe and I just had to undo it. Otherwise I'd have been screwed.. like those pipes!

The job was just to cap off an appliance, so I didn't want to go altering pipework and so on, except to put a cap on it.

Should have unions or flanges somewhere appropriate to break in to the pipe.

Or you cut and thread an existing piece and add a union. You can hand thread in place if you have to. Or hire a corded or cordless electric banjo.
