Is there any problem using galvanized pipe for natural gas instead of regular black pipe?

Answer:
There was a time when some jurisdictions did not allow galvanized because of the possibility of the zinc coating flaking off inside the pipe, and clogging orifices and valves. Most places do allow it now. Figure the drip legs take care of problems. Some areas still allow black outside but require it to be painted. The advantage of Black is that it is a little cheaper.
