[[Combustion]] cannons don't need to be made from pressure rated pipe in most cases, but if you don't mind the weight and cost, the additional safety provided by the pipe can only benefit your cannon.

	==PVC and Combustion Cannons==		==PVC and Combustion Cannons==

	Generally most spudders who build combustion cannons will not use pressure rated PVC due to the ~~combustions~~ low pressure spike and the cost and weight of ~~Pressure Rated~~ PVC.

Generally, most spudders who build combustion cannons will not use pressure rated PVC due to the relatively low pressure spike generated by most combustion cannons, and the cost and weight of pressure rated PVC. About 30-45 PSI is generated in hairspray fueled cannons and about 60-75 PSI in [[propane]] or [[MAPP]] powered cannons, which DWV (Non-Pressure Rated) PVC or ABS can typically withstand. However, wall thickness should be taken into account if the pipe is not rated.

	There have been few reports of ~~people having combustions made from~~ DWV PVC ~~blowing up on them~~, but this is probably ~~because of~~ pipe fatigue, thin-wall PVC ~~used~~ or cracks formed from threaded fittings in the chamber.		There have been few reports of DWV PVC combustion cannons failing, but this is probably due to pipe fatigue, thin-wall PVC usage, or cracks formed from threaded fittings connected to the chamber.

	~~If you are thinking of making a basic or advanced combustion, DWV ABS is probably the best choice aside from the rarely found, Pressure Rated ABS~~.		Advanced Combustion cannons should be constructed with pressure rated pipes.

Pressure rated PVC is the most common pneumatic cannon material because of the reasonably low cost, availability, and relatively low weight.
