Want this question answered?
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.
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
You should use black pipe -- Galv. pipe will flake off inside of pipe
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.
Use only black pipe
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.
Galvanized pipe will be silver/gray color. Copper will be copper. Use a magnet, it'll stick to galvanized pipe but not to copper. Drinking water lines should not be black steel pipe.
ya the galvanized pipecan be use in undergrounds,,, because it is an iron pipe
You can use pipe thread sealant aka "Pipe Dope" you can get this at most hardware stores.
You can't. There is no fitting to do this. Galvanized has to be threaded.
NO..copper,black iron, galvanized for gas pipe.never use plasticp solvents or glue.gas does not react well with other chemicals.
