4500's safe?

[synreal]

i believe it is 5/3rds the rated pressure.

[CRiZO]

yeah they are totally safe, even if the tank was to bust, it would do nothing more than crack open and let all the air out. I'd personally be more afraid of the chaos going on in a co2 bottle.

Syn? 5 out of 3?

FalconGuy016, at the AO day in South Carolina, the field owner mistakenly filled my 68/3000 stubby to 4500. There was no problem then, or now, with it. Considering the tens of thousands, if not hundreds of thousands, of high pressure fibre-wrapped tanks in industry, military, firefighting, and paintball use, to hear of one failing is rare enough to cause a huge sensation in the news. I have never heard of one failing (bursting) while in use, but only during a fill, and those have been attributed to poor handling and/or ignorance of fill procedures.

Keep the tank free from dings, scrapes or cuts, honor the hydro dates, and don't worry about it

[synreal]

unless i heard wrong, hydro testing involves filling a tank to 5/3rds its rated pressure (ie: 5000psi in a 3k tank), releasing the pressure and making sure the tank returns(within spec) to its original size (too much stretch/deformation and it fails hydro)

My 3k flatline was tested to 5k...

[FalconGuy016]

No my dad's a paintballer its ok

[FalconGuy016]

are 4500's a little bigger?

[banzaimf]

When originally tested to destruction for a design of bottle, Burst pressure of the bottle will be 4 times the operating pressure. For Mil Spec bottles, burst pressure will be 10 times the rated operating pressure of the bottle. Hydrostatic testing uses different ratings due to the fact that they are not trying to test to destruction.

Hoppy, I disagree w/ you bud... There's no reason to FEAR it, and most things for that matter, but there is a reason to be Weary...

Think about it, do you wanna be scared out of your wits running around w/ one of those things? Won't be pretty...

lol

thats why no fear = BAD
All fear= BAD
1/2 and 1/2 = kicks but

fine mabey fear wasnt the best word but u knew what i was trying to say.

[Hexis]

synreal is correct. Hydro testing involves filling a tank to 5/3rds it's rated pressure. 5000psi for a 3000psi tank, 7500psi for a 4500psi tank and 8333.33psi for a 5000psi tank. The tank's displacement is measured before, during and after the test and that is used to determine if it's safe for further use. So a 3000psi tank accidently filled to 4500psi should not blow up, but it will stress the tank, and if done so on a regular basis it could rupture. Stick with the rated pressure, it's rated that for a reason.

Hey, are 4500's a little bigger? For more material used or something

I have seen tranks blow under pressure. Air expands and contracts with weather, which most people dont think of. thats unsafe. What about regs that arnt put on right, that happens some times. another thing, your running around with a tank that is underpressure, if you drop it on a rock, it could explode. its liek running with a knife in your hand!

[FalconGuy016]

the PMI story wasnt in the news or anything

You have a point! Maybe you should stop playing paintball?

jeff jeff jeff

yes the tank is very safe
(kinda funny me telling you this)
