Condemn Rate

How often do tanks get condemned after a rehydro test? I figured tank that get dropped, abused, etc will be more likely to fail rehydro, but it'd be interesting to know if a particular brand tends to fail rehydro more often.

Then has anyone gotten their own tank condemned?

Don't forget the other fail method - end of lifespan.

As for which brand?......My vote would be GCI

It's rather rare for a tank to fail for reasons other then the life span coming up. It happens but it's not that rare unless you really beat on a tank or something structurally isn't right.

For us, its very rare that we have to condemn a bottle. There isn't one particular manufacturer that stands out above the others as far as failure rates are concerned; its really hit or miss. Again, its very rare that we ever have to condemn a tank when we hydro test.

Pretty much most rehydro places will tell you, they do not remember the last time they had to condemn a cylinder. Its very few, and far between.

Tanks can take a beating(performance wise, not physical damage) for years. and pass hydro just fine.

Heh. Hence I bought a ninja tank, and I'm buying another one now.

Can you say how many, in how many years that you guys have been doing hydrotesting, have failed? Maybe how many tanks you guys have hydrotested altogether?

You have to remember that the carbon fiber wrapped tanks are lined with a thin shell of aluminum inside. Rough handling can damage the outside but most booboos can generally be fixed. It takes bad air fills to damage the aluminum inside. Wet fills can start the aluminum corroding and that can lead to pitting.

If your field or store is taking care of their fill system and you don't play football with your tank, it is highly unlikely that you will ever fail a hydro.

My crossover carbon tank actually failed hydro yesterday. They said it expanded 3% past the allowed limit. Off to buy a new tank I guess. Anyone want a fancy paperweight?

It happens! Most likely from too fast or too high pressure fills unless it was corroded inside.

My first Ninja tank just failed its first rehydro test. Could the crack in the outside clear coat have anything to do with it?

Holy necrothreads.

It could. It depends on the reason it failed if it was a visual or if they hydrostatically tested it and it didn't expand/contract within the REE limit; which could have then caused the crack.

I hydro any where from 10-30 paintball cylinders a week, failure due to excessive expansion is rare but we get a couple each year. Most of the failures we have are more from internal cracks at the threads or thread damage. We usually fail a couple a month due to thread related issues.
Common reasons for rejection
Thread damage
Cracks internal and external
Non dot cylinders
Dot sp number expired
Exposed fibers
Invalid dot number/ manufacture (gci)

I would ask for the associated paper work from the company that did the hydro, if there was damage on the outside there is very specific rules regarding there size and degree of damage. If it is cracks in the UV protective coating it may not harm the function of the cylinder but because of the depth of them they will not pass a visual inspection in accordance of dot 49 cfr. If it failed do to the cracks the reason would be listed as having level 2 damage, level one damage would be repairable.

Thank you Velocity Joe! I was told it failed but I haven't had a chance to pick it up yet from the store. Perfect time to want a Ninja 77SL!!
