The registration form for the Finnish national championships now for the first time includes a box where you have to enter the expiry date of your AP's cylinder.
This is no problem if I decide to shoot my LP10, but what if I'd like to shoot my CM162EI instead? The only text I can find on the cylinder is:
CM(r)
Morini(r) Competition Arms S.A.
NET: 1.000 Kg / 2.205 lb
AIR: 0.022 Kg / 0.048 lb
Pmax: 300 Bar / 4.351 Psi
I bought the Morini used, and have no idea how old the cylinders are. The gun is the 15 volt version, serial number 15837.
Based on this information, do you have any idea how old the cylinders and/or the gun might be?
No date on Morini cylinder, but required @ Finnish nationals

it's an issue in the netherlands too.
Due to a few accidents with exploding cylinders the rule is that the the cylinder has to be checked every 10 years.
this checking has to be perfomed by a qualified company.
they add a new date stamp so that th cylinder is valid fot another 10 years.
by the way: the accidents occured in germany.

I'd love to know who's doing the checks and able to verify them for another 10 years. None of the manufacturers that I'm aware of are doing it.madmull wrote:it's an issue in the netherlands too.

Also the only accidents that I've seen described were due to manufacturing faults and the subject of product recalls.

correct, the manufactures don't check them because they love to sell new cilinders.RobStubbs wrote: I'd love to know who's doing the checks and able to verify them for another 10 years. None of the manufacturers that I'm aware of are doing it.

Stelljes and klingner in germany test the cilinders, it's expensive.
I read that there are companies who check diving equipment, also can do these tests. One guy told me that the test are being performed with water and that he advised me tobuy a new pistol when this was needed with my cilinders.
the problem occured with the older model cilinders (the one with no manometers) it seemed that people where overloading these tubes.
Re: No date on Morini cylinder, but required @ Finnish natio
Perhaps just convincing your Natioanal body to not be so pedantic might be a place to start. Ask them to show some evidence that any airgun air cylinder anywhere has ever failed due to age.nc513 wrote:The registration form for the Finnish national championships now for the first time includes a box where you have to enter the expiry date of your AP's cylinder.
Dive cylyinders are a totally different proposition and yes they pressure test those with water as I recall. I have no idea how you would go about testing the small cylinders we use, if I needed to use <10 year old cylinders I'd just buy a new one when needed.madmull wrote:RobStubbs wrote: Stelljes and klingner in germany test the cilinders, it's expensive.

The owner of the diving company where we get our club bottles filled was intrigued when I told him of this. He just could not understand why people wanted to make rules for an item that is excluded from the current pressure test regulations! He went on to say that he would be happy to arrange a hydraulic test of an airgun cylinder and supply a test certificate, it would cost around GBP30.Dive cylyinders are a totally different proposition and yes they pressure test those with water as I recall.

No Hammerli cylinder has ever been good for twenty years, they don't even stock spares anymore for the K1 and K2 - so the problem solves itself :-)
Pure revenue generator. I've never seen anything blow up, not a CO2 (and many of those are 30 years old, which - even at 80 bar - should prove something), no PA and no CA...

So according to Tycho's comment, my Morini's cylinders are probably around 12-13 years old, but I don't really have any way of proving that.
"These are from the late 90's and Morini says their service life is at least 20 years. Can I go shoot now?".
By the way, what date do the manufacturers usually stamp on the cylinders; the manufacturing date or the expiration date?
I would assume that the date on my LP10's cylinders is the manufacturing date.
j-team: The 2012 Finnish nationals might be a bit exceptional; I suspect that the organizers are practising the same procedures they will be using at the European championships in February. The 2013 organizers might choose to use a different strategy, I suppose.
