PVC pipe-not for compressed gas service
I added this to the bottom of Carl's thread on air compressors, but felt it was important enough for it's own thread, so everyone has a better chance of seeing it.
Just wanted to make sure all of you understand that PVC pipe is not rated for any pressurized gas service. It is made of brittle plastic that when stressed may burst. When PVC does burst it fragments like a grenade, sending shrapnel flying that can do serious bodily injury or even kill. This is not something that you would want to happen to you, your family, or friends.
OSHA has regulations against using it for any pressurized gas service, and it is illegal to do so. I'm not trying to preach, but merely inform, for your safety. I have seen the aftermath of a PVC explosion and it's not pretty. It is literally a bomb going off with razor sharp shrapnel.
It's a little more expensive to do your air system with heavy wall copper or iron pipe (mine's 3/4" galvanized). But it sure is nice to know that it's not going to blow up and hurt someone.
I know somebody is going to say, "well, I know a shop that has had PVC pipe in their air system for years and never had a problem". I know of some too, but it's foolish, irresponsible, and they are living on borrowed time. It's not "if" it blows, but "when", and you don't want to be responsible for hurting a loved one.
Off my soapbox now, I hope this hasn't fallen on deaf ears.
But it's a dry heat!
