Well, I can confirm first hand the PVC will fail by explosively shattering. I
had thought the same thing about the pressure ratings etc. and ran a line from
the back of a shop to the front of a store. Fortunately it was above a dropped
ceiling because that served to stop the shrapnel when it let go. It made a big
noise when it did let go that was only connected to a small tank around 100
psi. Never did find all the pieces. About 6 inches of the pipe were badly
fractured and I never did find all the pieces.The fracture occurred in the
middle of a section of pipe nowhere near a joint or anything else I could
identify as creating any special stress.
So even though it's cheap and easy to work with I'd never do it again. Even if
no one gets hurt or nothing gets damaged it just isn't worth the effort of
doing it twice.
