Morini Cylinders
Some might be interested; I have just seen a photo of a very recent Morini cylinder.
They have fallen into line with the others by giving a 10 year maximum.

You can also find other reasons for this move:
- First Morini sells a lot of pistols in Germany. The 10 years validity of cylinders comes from Germany, easy to understand that they want to comply with the rule of a big market.
- Second, Morini doesn't manufacture the cylinders themselves, they most probably use the same supplier as some other manufacturers and this supplier follow the 10 year validity rule.

Tycho, you are absolutely 100% correct.Tycho wrote:The whole thing is a joke. The only cylinders ever that exploded were faulty ones, not old ones. It's a revenue generator, nothing else. And there was no problem in Germany with the 20 years of the Morini tubes, so why change? To sell more stuff.
I have no intention of replacing my air cylinders when they are 10 years old.
When there was a problem with the Anschutz rifle cylinders, the name of the manufacturer was mentioned. Same in the FWB document explaining the 10 year limit and the process to re-check the steel cylinders.Richard H wrote:Haven't been to Morini but I've watched the others manufacture the cylinders in house, where do you get your info from?
The cylinders are machined from aluminium billets.
The use of other suppliers for parts is not limited to the cylinders, many parts are manufactured and sometimes designed by sub-contractors. The most known one is the barrel with Lothar Walther.
This 10 years limit is just a matter of legal protection, the risk of people injuries in case of explosion is high. The risk that some cylinder explode is probably very low but the manufacturers cover themselves by setting a limit. ISSF does the same referring to the manufacturers rules.
About making money with cylinder replacement, if I remember well, I read that Walther offer a free cylinder replacement after 10 years for the new LP400 ?

Not exactly.TPE wrote:Is there a rule that gives the competition organizers power no to accept your equipment if you have an old cylinder not under warranty of the manufacturer?
The most applicable rule is 6.2.2.8
"It is the shooter‟s responsibility that any air or Co2 cylinder has been certified as safe and is still within the validity date."
There is however an overiding rule, part of 6.2.1, which states "The Organizing Committee bears the responsibility for safety."
If they consider the use of an out of date cylinder to be a safety issue then they are entitled to stop it from being used.
Jipe that was the supplier of the raw material (the billets), the faulty ones had sub surface defects in the billet that should have been caught when the billets were tested with ultra sound ( the defect was actually a lap) and would have been easily detected (all billets are suppose to be tested usually at both the supplier and the customers end). I use to run a metallurgical lab, and worked in a lab a steel mill, prior to being a quality/reliability engineer in the automotive industry. Someone dropped the ball and didn't do what they were suppose to do and for that they now passed the ball to the consumer who can now pay the cost for their screw up.

I seem to recall someone on this forum complaining that he had sent a cylinder in to a reputable shop for repair - replacement seal? - and the shop told him that the cylinder was out of date and destroyed it without consulting the owner first. Apparently, the shop did not want the liability for returning an out of date cylinder even if they did not work on it.
One point was not brought up, and the metallurgist in this discussion might comment on it. Every time a cylinder is filled it expands slightly; the filling cycle can cause a work hardening of the metal that may make it more susceptible to catastrophic failure. I have used some very hefty aluminum centrifuge rotors that appeared perfect but had to be derated or retired after so many hours of use. The stress of cycles of expansion under centrifugal force makes them unsafe. It may be that the 10 year limit is a proxy for the number of fill cycles; a top competitor may be approaching the limits of the cylinder in ten years while the casual shooters and wannabe's could safely go a lot longer.
How much does a new cylinder cost anyway? I am wondering if the cost is amortized over ten years, is it significant w/ respect to the cost of pellets, targets, and other expenses related to shooting and competing?

I saw this photo a while ago when AP shopping: http://www.flickr.com/photos/stenholsfo ... otostream/, taken on Nov 6 2010. Would love to know if Morini is officially part of the rip-off consortium now.
Luckily I have some late 2008 cylinders "made to higher specifications" that are good for 20 years... zzzzzz

Of course it doesn't matter: it is metal fatigue that can cause problem. If the cylinders were never used and stored in a right way (no corrosion), the manufacturing date doesn't matter.Richard H wrote:Here's a little funny tidbit, I ordered a new cylinder from a manufacture, who promptly offered me an older one. I brought expiry date issue up to them and was told that it doesn't really matter the cylinders are all ok. Go figure.
The problem is that once the cylinder are sold, it is not possible to know if they were used often or not. Therefore the use of the manufacturing date to define an expiry date.
As said Tycho, liability is the problem. No company would take the risk of being liable in case of accident if it is not necessary to do so. It is not a question of cojones, it is just business.
