I'm getting ready to buy an air compressor, one of the 20-gallon,
belt-drive type units. I figure this gives me the largest comperssor
size I can get in a portable unit. Obivously, more air is better, and
if I need more air, the logical solution is a larger air reservoir.
My question is this: Since Schedule 40 PVC is rated to ~240 psi and
my 'presser only goes to 135, why not use large-diameter (6 or 8 inch)
pipe, cap both ends, tap one of them and hang it from the ceiling
(connected to the 20-gallon tank with a flexible hose)?
I realize that plastic is not the recommended material for compressed
air systems, but that is because hoses, etc attached to small-diameter
PVC tend to get pulled too hard and crack the plastic pipe. This is
Not A Good Thing. However, with nothing attached to the reservoir
that should get pulled on, are there any other potential problems?
