New air compressor, copper or iron pipe Options

Good evening everyone

For those of you with large compressors what kind of lines are you running through your garage?

Thanks

3/4 pvc is certainly strong enough to handle 125psi but the issue is with how the pipe explodes, if you will. when blk, galv or copper pipe/ftg's break it doesn't propel flying shrapnel like pvc can and does. i'll bet Rick or one of the other ins adjuster's here can tell some stories. condensation is going to happen no matter what pipe material is used. most importantly, installation is the key. vertical drops should have a 6" drip leg with a hose bibb on the end to drain. air outlet should come from a tee ftg at least 6" above the end of the drip leg. all horizontal lines should be installed with enough slope as to allow for proper drainage back to the vertical drop preceding it. in other words don't give the pipe a place to trap the water. if you do use pvc do not expose it to sunlight as UV rays deteriorate the material and know that the psi ratings for pvc aren't the same at 30F as they are at 70F. slap a piece of pvc pipe against a brick on a freezing day.
