plumbing air lines - any height issues

when running black pipe is there a minimum or max height to mount the piping? i do not need or want to go right up to the crane rails int he shop.

Not as far as I'm concerned. You don't want them low enough to be impacted on by processes in the plant.

You also want the main to have a few degrees of slant to a common point for drainage, and you want to take the drop lines off the top of the main, not the bottom.

You may want to have a look at the info that is on the Plumbing Compressed Air pages linked from the site map.

Cheers,
