Air tank manufactured date & expiration date question

[PewPewTac]

If I understand correctly, the tank was manufactured on March 2013, and it is good for 15 years. Which means the tank expires on March 2028 correct?
I also saw a thread on here that said there is a new DOT regulation could push it to an additional 15 yrs since this is a Carbon fiber tank... That would be cool if 15 yrs is added, it would save me $ from buying a new one in a few years.

You can have it recertified too. I'm not sure how long a recertification lasts.

From a conversation a couple years ago, I saved this link as the company authorized to do life extensions. You would have to ship your tank to them.

And, a pretty good thread on the topic: https://airgunguild.com/airgun-tank...ended-life-for-carbon-fiber-tanks!!/msg16457/

Too bad the company that does the recertification charges more than just buying another tank with 4 or 5 years service remaining.

Carbon fiber, tanks have to be hydrostatically tested every three years.

Carbon fiber, tanks have to be hydrostatically tested every three years.

DOT requirements are every 5 years for SCBA carbon tanks.

DOT requirements are every 5 years for SCBA carbon tanks.

I think I’m looking at the Nfpa requirements for composite cylinders which is every 3 years. I’m a retired firefighter.

Warning, A carbon fiber tank that is bad will unrape a few carbon raps and go shhhhhhhhhhhh, You cant hear it, most soap spray bottles will not pick it up
A full bath tub will show the bubbles,,,, Its a built in safety on carbon tanks, NO BOOM. I just tossed my 2nd carbon fiber tank because of this, it was 28 years old and tossed off a second story building on cement,,, It was given to me and I passed it on to the dump.

Has anybody had a tank blow apart on a gun? I knw my Ataman is about ten years old.... and may be my Wildcat. Who would even bother or be able to recertify those little tanks? Or just buy a new tank every ten years? ($)

That's a moot point if you have your own compressor and fill your own tanks.

own compressor

I am getting my own compressor, and i will have no qualms filling my old 200 BAR 12 L bottle, even if it is way past the " EOL " date.
CUZ you see in all those years, well the bottle have just been sitting idle collecting dust, actually it have only been filled 6 - 7 times in all the years since i got it brand new.
So i will not feel i am endangering my own health or my friends health as he have a similar tank of the same age,

That being said before i put it on my new compressor, i am going to take it apart and do a visual inspection of its inside, but as it have always been filled at a dive shop and been stored inside a nice warm apartment i have no doubt it will be clean and dry inside.

Bottles / pipes on a PCP air rifle, well i dont know what to say, my Cyclone are over 10 years old now, so a suppose it should have a new pressure vessel.
But as it also like my 200 BAR tank have just been sitting idle mostly since 2012, i am going to take my chance with it.

Here bottles have to be pressure tested every 5 years, and it cost 100 USD to have done ( minus shipping cost ) A < 1L bottle Pressure test only slightly cheaper than a 12 - 20 L bottle.

Vessels under 2" in diameter are not regulated and do not require testing or certification. That doesn't mean it wouldn't be a good idea to at least do a visual during routine maintenance. You could even send it off to a testing site and have it checked voluntarily.

It’s good for 15 years. It is possible to get it extended another 15 years. However, I’ve researched that quite a bit and to avoid a lengthy explanation I will just say it makes no sense economically. You might as well buy another tank.
