That galvanized elbow is a no-no for use with propane.
It depends on what code you are dealing with. for propane work most states have adopted NFPA #58 as the ruling code. NFPA 58 allows both black and galvanized pipe for propane gas however both types have to be certified ASTM A53 steel pipe so there wouldn't be any difference in the strength of the pipe. the only difference is in the Galvanized coating.
When I was an Installer, I was told that the galvanize had some reaction with the propane. Now that I think about it, they don't galvanize the inside of the pipe-do they?
