Compressed air pipe material ~ use galvanized?

First, Thank you for the info provided on this site. I would like to know what you think of using galvanized pipe instead of copper. This is being used in a small shop, with nearly constant air use.

Generally speaking, I accept the recommendation of folks more in the know that you not use galvanized steel for compressed air use.

It isn't a safety issue, but rather, galvanized steel is reputed to have the galvanizing inside the pipe crack and flake off, and this travels downstream with your compressed air, and can create problems with your air using appliances.

I wouldn't use copper. My first choice, if I could afford it, would be copper. Next, I'd use a good quality RV Hose (rubber / vinyl ) and last, I'd use polyethylene.

Just my .02 cents worth.

Cheers,

Bill
