First off is it ok to use copper pipe for single pipe steam system. If so I tried removing the valve that comes up through the floor and it does'nt move. What happend is that 2 elbows that turn the pipe from the basement were moving instead. I can see the straight pipe from the basement coming up through the floor. I thought of cutting it ( snap cutter?) and somehow attaching copper pipe to it and run it srtaight up no elbows and put a new valve on. Can this be done? And how I don't think no hub copulings are for this type of application. Or if I must use black pipe how do you cut the old must you use new threads?

Only one way that I know of...

If you can't get the fitting apart, either break the fitting with a lump hammer or cut the pipe with a Sawzall. Then you thread the pipe in place or try to unthread it from a fitting. I doubt it will come apart.

Without the right tools, forget it. When you work with this old stuff you have to have the materials, tools and guts to be prepared for a lot more work than you imagined. Which means if you really don't know what you are doing, wait for the warm weather so you're not running around like a nut trying to put things back together.

Don't use copper if you can absolutely help it. One day it will leak.

Different metals expand/contract at different rates so copper will expand/contract differently than the black pipe or radiators themselves and the fitting will eventually leak.

Sooo. . .

copper piping for the manifold is a bad idea? That is what was installed at my house a few years ago-should I get it redone
