Black iron pipe is used for gas installations but ONLY if the piping is indoors. Outdoor gas piping is usually done in galvanized pipe. Steam is also piped with black pipe, fire sprinkler and standpipe systems also use black pipe.
No.
You should use black pipe -- Galv. pipe will flake off inside of pipe
Yes.
Galvanized Iron pipe
Water does, so I am pretty sure steam will

To connect PVC to galvanized pipe, you can use a PVC to threaded adapter. This adapter has a female threaded end that can be screwed onto the male threaded end of the galvanized pipe. Make sure to use Teflon tape on the threads to create a tight seal and prevent leaks.
Yes, it's better pipe.

No, it is not safe to use galvanized pipe for gas because the zinc coating on the pipe can react with the gas and cause corrosion, leading to potential leaks and safety hazards. It is recommended to use black steel pipe or other materials specifically designed for gas applications.
Depends on local codes I use Galvanized piping and fitting when I know the piping is going to be exposed to moisture (dampness) or the elements
