Re: compressed airline

Kind of a strange question for an electrical forum but I was kinda looking for this information a few years ago also.

Short answer is there really isn't anything beyond maybe the local plumbing codes. Some jurisdictions may still require black iron pipe. Most is done with copper and sweat fittings today.

I think OSHA may require "excessive flow cutoff devices" on portable hoses to shut off the air supply if the hose is cut. This is to prevent the hose from whipping around, possibly hurting someone.

There are design practices for compresed air systems, you might go to Ingersol-Rand and see what they have. Take a look also to see if the pipe manufacturer has any recommendations.

Hal is on thr right track as some of the compressor manufacturers have system layouts available. They include things I didn't even think about like running the pipe downhill to water purge valves etc..

A lot on industrial plants around my area use a green plastic pipe for air lines. This pipe is specifically approved for compressed air use (ordinary PVC pipe is unsafe for this use and is forbidden by OSHA.) The pipe manufacturer has some information about pipe sizing and support requirements.
