Most codes do not allow Galvanized piping/fittings on gas piping. I have used galvanized pipe/fittings on exterior gas piping before in the state of Michigan but other states do not allows this. Check with your local code authorities.
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
It is not advisable to bury a galvanized gas lineMost civilized codes will not allow galvanized piping to be buried under ground even for waste or venting it is against good plumbing practices. I have seen quite a bit of buried galvanized pipe, both for water and gas. It does rust out eventually. Interestingly enough, it usually rusts through at point at which it comes up out of the ground.
NO!! Black iron pipe has a special coating to resist the highly corrosive effect of natural gas. Galvenized pipe CANNOT be used for gas service.

What is the application as many times such as natural gas it is permissible as gas lines exposed to the elements have to be protected painted / insulated or galvanized piping vanized piping
No.
NO..copper,black iron, galvanized for gas pipe.never use plasticp solvents or glue.gas does not react well with other chemicals.

Galvanized pipe is used for natural gas lines and pressure vent lines, and for electrical conduits. As a water supply or drain pipe, it is subject to rusting over time.
Use only black pipe
Even though I am in a different country, you should use Black Iron pipe, not galvanized. The other option is copper. Check your local bylaws, GET A PERMIT! This is essential. If you screw up and do not have a permit, you will NOT be covered by insurance!

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
Approved pipe joint compounds
Hard copper using silfoss for the joints, copper tubing using flare connections, and screwed black iron pipe. You should hire a Journeyman gas fitter and get a permit for any gas work done as if there is a problem, it won't be covered by your insurance!!!!
