What is a maximum safe psi to load into a pvc pipe without having the threat of it blowing up?

Question

I am planning on building o air powered cannon out of 2'' pvc.

Answer 1

it should say right on the pipe

just get a thick pvc pipe

but the psi load should be stamped on the pipe itself

Answer 2

Now that is a trick question. First of all, It depends on the schedule of the pipe. (Thickness).It also depends on fittings. how many, what kind. Now comes the biggest question. What kind of glue and if you are using primer with glue. Another factor that comes into play with PVC, P.S.I. rating is temperature. PVC pipe and fittings are pressure rated for continuous use at 400 psi at 73.4 F and 100 psi at 180 F. As temperature increases, pressure rating decreases. Under no circumstances should temperature exceed 212 F. Plastics are affected by ultraviolet radiation. Pigments are added to the PVC to make pipe and fittings resistant to degradation. PVC can be exposed to sunlight during construction, but prolonged exposure to the sun is not advised unless protected by a water-based latex paint.
This should answer your question. Don't forget length also plays a factor.

Answer 3

Actually, I think the maximum pressure that a pvc pipe can hold is actually listed somewhere on a length of the pipe. If not, go to a Home Depot and ask there - I'm sure someone there would know. By the way - don't shoot your eye out! ha

Answer 4

what is the maximum safe psi to load in a 3" 2 long pvc pipe.

Answer 5

Something to keep in mind is that the the pressure rating you will see marked on the pipe you will find at Home Depot and similar stores is for water pressure. PVC pipe is not usually considered "safe" for compressed air, particularly if you plan on using it as close to the maximum rating. PVC can shatter if it fails creating shrapnel. There are special grades of ABS pipe designed for compressed air use, but it is not so readily available to amateurs.

Answer 6

Now it particularly is a trick question. in the beginning, It relies upon on the schedule of the pipe. (Thickness).It additionally relies upon on fittings. what proportion, what type. Now comes the biggest question. what style of glue and while you're utilising primer with glue. yet another element that comes into play with p.c., P.S.I. score is temperature. %pipe and fittings are tension rated for non-end use at 4 hundred psi at seventy 3.4 F and one hundred psi at one hundred eighty F. As temperature will strengthen, tension score decreases. under no situations ought to temperature exceed 212 F. Plastics are stricken by ultraviolet radiation. Pigments are further to the %to make pipe and fittings proof against degradation. %could be uncovered to photograph voltaic for the duration of shape, yet prolonged exposure to the solar isn't recommended until secure by a water-based latex paint. this ought to respond to your question. do not forget approximately length additionally performs a element.

Answer 7

The chart from the link given above follow that for the maximum operating pressure. I am not positive, but they come up with that pressure rating for 100,000 hours of use. Follow this for your cannon and you should be safe.

The burst pressure they have listed on that chart is for 10 hours of use I think. I forget the exact testing standards they use to rate plastic pipe but that will give an idea on how they came up with the two different pressure ratings.

Answer 8

The design pressure of the pipe is written on the pipe.

Answer 9

Be REAL careful.
'Static`, (what you will get from references),
is not the same as
dynamic, (what you will be dealing with),
when you're talking about pressure.
Leave a large safety factor.
