Gas piping

[Larry Hood]

Is galvanized pipe and fittings approved for gas systems or should they be black steel for the interior supply to the appliances?

[Jerry Peck]

Galvanized is okay by most (if not all) codes ... almost most places allow galvanized (there may be a few places which prohibit galvanized, but probably not many).

Jerry,
Thanks for the input.I had read at one time that the galvanizing would break down or have a chemical reaction and flake off and clog the line,but if approved so be it.
