If a brass fitting was blown out at that pressure, from that close, into his eye (as the video says it does), there is no way in hell that guy still has the eye. Unless he got EXTREMELY lucky and it walloped his orbital bone instead.

Either way...ouch

Actually....let's just wear goggles all the time.

Yeesh, that's borderline snuff. I don't consider anything about that video a "bonus."

I'm just going to assume that no one was seriously injured in this video. Otherwise it's really sick, and I have to feel bad about laughing my ass off.

I don't find it funny, but I think it's a good reminder of why you should wear goggles for stuff like this. I take that position with my 7-year old son: If you want to do 'dangerous' stuff, let's do it. But let's be safe about it. Goggles, face-shields, hearing-protection, coveralls, or whatever the situation calls for. Also, situational awareness helps too. Like don't put your face directly over the 'projectile' (in this case a pipe-fitting).

I don't care if I look like an idiot 999 times if, during that 1 failure, I'm wearing the protection when it counts.

I've built several pneumo guns out of pvc. The PVC solvent, or "glue" as subby put it, can definitely hold up to the pressure. Certainly more pressure than the PVC itself is rated for.

If you're going to use a fitting like that, get the kind that bolts on. Always wear safety equipment. Never over-charge your vessel. Sources of compressed air can cause very serious injury in ways you would never think of. Charged or not, never point one at something you don't want to destroy.

/My pride and joy is a 13' cannon with a 2" diameter barrel.
//Built the quick release valve myself out of a 6" PVC T joint.
///4:1 pressure vessel to barrel volume = Lots of range.
 
2012-07-23 10:17:04 AM  
Dumb mother-farker!

First off, what kind of moron puts 125psi into PVC? My tennis ball / spud gun uses a pony keg as the pressure vessel and I only fill it to 100psi.
Second, even morons know not to jack around with a pressurized vessel. You screw with it before filling, not after it is loaded.
Third, the brass valve didn't come off - it was just the part of the launch chamber that hit him in the side of the face as the barrel broke away from the pressure chamber. It might have cracked his skull at the orbit, but clearly didn't penetrate his eye.
 
2012-07-23 10:42:11 AM  
Uh, looks to me like the top pipe blew out of the bottom pipe and hit him... not the brass bit.

madgonad: First off, what kind of moron puts 125psi into PVC?


The kind of moron who knows what pressure his PVC pipe is rated to: Link
FYI, I charge my systems to 150 psi (150 psi blowoff valve FTW).

If I had to guess, I'd say the guy either over-pressurized his system (more than the stated 125 PSI) or he did a shotty job of joining his fittings.

1. Primer.
2. Solvent.
3. TIME.

Those ratings on PVC are for water pressure, not air. Some manufacturers have even stamped 'not for compressed air' on their pipe, but nobody cares because it usually works fine. In the video it looks like the failure was in the connection of the two elbow bends. That is the most likely source of flexing on this design and I don't see any braces or bands to prevent the flexing (and weakening) at that point. I built mine back when I was teaching and I used it every year in class. Safe and predictable. PVC pipe was designed to move water with minimal agitation. The abuse, stress of rapid pressurization/release, and being flexed and jarred have an obvious deleterious impact on the pressure chamber.

As far as I'm aware, PSI is PSI. Do you know why it would matter if the rating was for water vs. air?

I would have at least used schedule 80.

I think he was suggesting the rapidness of the buildup to pressure and the depressurization would cause the integrity to fail not the pressure it ultimately reaches.

Water molecules are smaller than air. Could cause a joint to fail when water may not.

Let's go to a manufacturer.

"CAUTION: PVC Schedule 40 Pressure Fittings are not
recommended for use in compressed air or gas systems"

http://www.ejprescott.com/media/reference/PVCSch40PressureFitB-63.pdf

OSHA has something to say about it too.
http://www.osha.gov/dts/hib/hib_data/hib19880520.html
 
2012-07-23 01:54:14 PM  
They wouldn't be used for compressed WATER either. Schedule 40 isn't for anything that requires high pressure.

Honest Bender: As far as I'm aware, PSI is PSI. Do you know why it would matter if the rating was for water vs. air?


Because air is compressible where water is not. You can say that "PSI is PSI" but when a PVC pipe with water fails it's a dangerous outcome, but because of its incompressibility it doesn't create as much of a "pop". When a PVC pipe filled with air fails it's deadly. Because of that increased risk the maximum air pressure rating would be set much lower than that of water.
 
2012-07-23 03:11:59 PM  
How are you people not laughing at this? This dumbass forgot rule #1 of "playing" with dangerous items ... DON'T PUT YOUR FACE OVER IT Who doesn't laugh at people with facial burns post-4th of July?

Oh, I believe you when you say that PVC has separate ratings for water vs. gases. What set off my bullshiat detector was when you started talking about the relative sizes of water molecules vs. atmospheric molecules. How the fark would that cause a PVC joint to fail?

Microscopic fissures mixed with compressable gas. Once the hole is large enough more rushes out., the hole gets bigger. Might not happen with water. A lot greater potential for disaster.

Think about using fix-a-flat in a tire.

I've worked in a lot of high-risk environments where not thinking about safety was a quick way to lose your vision, appendages or possibly even death. Not taking the time to think about safety is dumb to the point of almost being socially irresponsibility, so yea, I laugh when only that person gets hurt.
