Re: Would PVC pipe work for an on board air tank?
I work with PVC, CPVC pipe all day long both schedule 80 and 40, from my 23 years experience with this stuff I would say you are putting yourself and any one around you to GREAT jeopardy when you pressurize this stuff, it has no real PSI rating for compressed air. It is highly fragile at compressed air pressures,80 psi and up, never mind the wall thickness of this stuff, you have to put some kind of cap on the end and they do not make a glue formula yet that will give the end caps or plugs the strength that is needed to contain it for an air system safely. I have seen this stuff used as air deliver in plants and they have paid out great sums of money for injuries to employees when they exploded. They WILL explode, if not now, they will later, PVC fatigues with age and gets more brittle with age, add UV and heat and this just increases the deterioration process. The glue also breaks down with the same properties. I would say again to stay away from this as a pressurized vessel.
