How Safe Are HP Tanks?

[Spartan X]

Considering what is to me an obvious danger of HPA tanks and the little respect that most people show for them I am very surprised there have not been more reported incidents with them then there have been.

Watch SCUBA people once with there tanks - most of them treat them as if they are filled with nitro-glycerin and might explode at the slightest tap.

Eh with scuba tank it's not so much as being carfull with them in the respect of diging them, rather with the valve. For some reason they made the valve and threads easy to brake...not to sure why that is. Thats the bigest danger...dropping the tank on tyhe valve. My scuba instructor told us one time a tank was falling off a bench on a boat, no one was close enough to catch it to they literally all jumped off the boat. The tanks valve broke off and shot threw the boats canapy and when some were far far away and they never found it.

is it dangerous for my co2 tanks to be under my bed for a while, both near full.

Only if your Air Conditioning goes out and your room becomes oven like...

Since your room is temperature controlled, I'd prefer to have them under a heavy piece of furnature (bed) than sitting in a garage that doesn't have any temperature control.

A guy who occasionally plays at my local field always fills his 3,000 PSI tank up to 4,500 PSI. Many of us have told him it is just a matter of time before something goes wrong with it. Does he care? No. Do we want to play around him while he has that tank? No.

Those are the kind of people who get injured in HPA accidents.

those are the kind of people you kick out of paintball fields.....

as for scuba tanks: we don't fear our tanks...we just respect them. The valves are sorta flimsy..and I have seen one go shooting....saw it take a chunk out of the side of a building...now that is impressive.

wow i have that gun(pic 2) at the locoal pro shop ill hav to ask chris if he knows anything about this... link please?

That tank was intentionally overfilled so that it would blow... I think it took some ungodly high pressure to do it (for some reason 12,000 PSI is in my head... but it was a while ago when I first saw that so I'm not certain). Thumbs up for burst disks.

Store your HPA tanks with some air in them, on the SCUBA tanks that we fill/run the booster from at the field they say to not drain them below 200 PSI, I'd assume that a similar number is good for HPA tanks.

Don't buy nitro duck.

Don't buy nitro duck.

any specific reason why? i used to have one (my first n2 tank, have only used crossfire since). But, 2 teammates still use nitro duck tanks without problems, and, mine never game me any issues.

Another reason not to allow self-fills. This, my friend, is a problem that your field owner should know about. Some people care more about convienance than safety.

THere's actually Military slo-mo footage of the same fiber wrapped HPA bottles that we use in paintball where they intentionally puncture the bottles with bullets. It's interesting because when the bottles are pierced its easy to see the fiber wrap separate from the other layers and allow the air inside them to vent.

HPA Tanks are safe enough provided they're well taken care of, serviced and inspected regularly, and have the propper burst disc assys. installed.

Inspecting you tank for dings, nicks, chips, and "dig" before you use them is an important part of maintaining these cylinders. Regular Hydro Testing is also well advised, the tanks themselves are run up several thousand psi above their rating to test for expansion, too much expansion and the tank fails, you get your bottle back with a hole drilled into it.

Personally I'm not concerned about any tank being particularly dangerous, they've all been through extensive testing buy DOT to declare them "safe" with propper handling and inspection. The lack of concern that many players display, however, over the maintinance of their gear is another point. Intentionally overfilling a cylinder above its service rating will likely not result in the failure of the tank through the 3 years it's hydro is good for, however it would be reasonable to assume that this tank, if overfilled regularly will fail hydro because it has been stressed excesively. The service pressure ratings (as I understand them anyway) are the pressures the cylinder is rated to carry 24/7 for the lifetime of the cylinder (15 years in the case of fiber tanks). The burst pressure is significantly higher than the service pressure so as to allow a considerable ammount of headroom for variables like ambient temp. and altitude changes among other things.

Bottom line, any tank which is within hydro and fails is due to the negligence/abuse of the user/owner. There is no reason one of these cylinders should fail within the 3 to 5 years between their Hydro Dates.

Hyrdo Testing...

From what I've heard/seen about Hydroing a tank... they are required to fill the tanks 75% OVER the norm pressure. Meaning a 4500psi tank, they take it to rougly 7800psi. In other words... they made the tanks to take a ton more than what you're putting in them. Most companies do this will all their products because they know people don't follow the guidelines, some tanks are weaker than others, etc etc. There's no way HPA tank companies could make these things under insurance policies if they were like strapping a bomb to you chest. Yea.. you can't drop them from the top of the Empire State Building, but I've jumped into more bunkers on my tank than I can remember.
