I can only recall of documentation of three SCUBA tanks exploding
There certainly must be more

What single individual was responsible for VIP= inspection of SCUBA cylinders ?

Maybe some can come up with the answers ????" '

The posts are beginning to remind me of a conversation I had at the New Mexico Blue hole diving center with a super duper instructor who informed me "There was No books, No magazines. No training manuals and no diving Certifications, before...…." ( guess the organization ?)

Now NO ONE has stated evidence or a recollection of an exploding steel or aluminum SCUBA tank.

A steel one did exploder and did damage some years ago-- an organization established the VIP program a long time before Bill High created his retirement program.

@Jiminy
Common knowledge for many years

What about Steel Cylinders? Especially those that you have witness or read about exploding ?

<<<Remember it it is not on google it didn't or couldn't occur >>>

What about them? Im sure they have exploded no tank is 100 percent safe

I would say that dropping a cylinder 3 feet onto concrete is far less extreme than this test.


BTW they do drop test planes. Or at least the closest analog practical. It's pretty hard to pick up 3/4 of a million pounds.


And a 100 year old steel cylinder would have only 20 test cycles if it made every hydro on time. Hardly extreme. Maybe my sarcasm meter is just off.

Anyway, that doesn't mean that DD's experience in failure analysis doesn't have any merit, simply that he is skeptical because he has seen "sure things" that turn out to be not so sure. He has determined that based on his experience, his tanks have a lifespan where his confidence in their performance falls below what he is comfortable with. No harm in that.

Now I don't agree with his retirement stance, I feel that the current testing of steel tanks by competent personnel is enough to keep them in service and catch any issues, but I know how I handle my tanks, and if there was ever a situation where I had any doubt, I would rectify that immediately. Things with unknown pedigree should rightly be subject to more scrutiny until their fitness for duty can be adequately surmised. The probability of a fluke accident will always exist.

Hi Johnny,

Thanks for taking the bait. Landing gear on AC are incredible pieces of machinery. They withstand shock loads from almost all axis.

They are mostly made of steel!

Aircraft designers still use heavy steel components in landing gear because, overall, it is one the best and strongest materials available. It is tuff, flexible, and durable. It has very high tensile strengths. It does not work-harden easily.

Steel scuba tanks are not the problem.

thanks,

Then I could change up my shtick.

We don't need no steenking changes.

That one might finally kill the thread.

Wait a minute, you are telling me that there are 5 times as many 6351 cylinders made then Ford Mustangs. Last year there was a big publicity about the 10-millionth mustang built. I see a lot of Mustangs. Owned a few as well. But my sightings of 6351 cylinders are rather rare. Where are all these millions of 6351s hiding at? They sure don't come through any dive shop or boat around me. A couple show up, but they are few and far between. Not even that many on Craig's list, and that is loaded with Mustangs.

Something about your numbers isn't adding up.

Hi broncobowsher,

I gave my source. It is a reputable source. Reputable sources do make mistakes.

Prove this statement and source incorrect:
"We know of 31 ruptures of 6351-T6 alloy cylinders out of more than 50 million manufactured."

Readers are leaders, are you neither? Please take that humorously and sarcastically.

I am enjoying this,
