Subject: Re: [PipingDesign] compressed air vs. screwed pipe
I would think screwed piping/fittings are find, but would suggest looking at using galvanized matreials. A lot of air systems have quite a bit of condensed water in them and galvanized materials would alleviate the problem of rusting and having particles collecting in your instrumentation items.
