I have a warning if your buying your PVC pipe from Bunnings. DO NOT BUY THE PIPE THERE it when BOOM!!!!!! on me at 80 psi after 100 or so shots that was the barrel and that was the only pipe i bought from Bunnings. You can buy the PVC fittings from there that is fine if you wanna buy pipe go to an irrigation store!!!!!!!
( the barrel Exploded at 80 psi after around 100 shots. It shot a 3 inch long pvc bit 10 metre's away from me)

But warming the pipe will make it less brittle

Bunnings sell both thinwall and rated pipe. They tend to keep the rated pipe away from the fittings. You just messed up.more_eggs wrote:Research before builds generally makes them safer...

I'll add to this one too, while it's generally considered safe enough to use dwv for basic combustion cannons, I don't trust bunnings dwv either. Had a few end caps blow off on the first shot on a very basic spray cannon. Though, pressure rated pipe is rated. Look for the pn#. multiply that number by 14.5 and that gives you a rating in psi. E.g: pn8 = 8x14.5 = rated to 116 psi under normal conditions.

pn number is bar instead of psi.. multiplying it by 14.5 is just the conversion process to PSI.cfb_rolley wrote:though, pressure rated pipe is rated. Look for the pn#. multiply that number by 14.5 and that gives you a rating in psi. E.g: pn8 = 8x14.5 = rated to 116 psi under normal conditions.

Yep, but I wouldn't have a clue about converting to kpa though.Davidvaini wrote:pn number is bar instead of psi.. multiplying it by 14.5 is just the conversion process to PSI.cfb_rolley wrote:though, pressure rated pipe is rated.

I've experienced an explosion or 3 with PVC,Pressure pipe and DWV.
Safety pressure ratings are there for a reason,Follow them!
DWV is designed to take a small amount of pressure (gravity mainly) but personaly for anything other then a spray 'n' pray combustion I don't trust it.
