Most shops I have seen use iron pipe for air, but I was just looking at a
couple on-line specs sheets on PVC and it looks like if I were to
distribute air at 125 PSI in my shop using 1" Schedule 40 PVC I would have
about a 30% safety margin at the worst case scenario. That's based on
120F operating temperature. While yes it does hit 120F here in the desert
once in a great while I don't think its ever gotten above 105 in the shop
building. Better safe than sorry though.

Wadda ya think?

P.S. I have seen other shops use PVC also, and they said they never had
any problems.



Bad idea!
I also have used PVC pipe for air lines, but after seeing the carnage that
ensues when a line fails I tore it all out of my shop. Copper, black pipe,
rubber, are fine, but no to PVC!
