Dacor 2250 after tumbling etc has clean rust pock marks approx 40 percent of tank safe to full fill or partial fill 1200-1600 psi?
@scubatechkeylargo 10 күн бұрын
40% is a large amount of corrosion, anything over 20% is considered a fail. I can't recommend to continue service on that cylinder. Thanks for the question.

Very professional and simple plus educational You mention that the Hydro test is every 5 years Unfortunately In Australia the most over governed over legislated diving industry in the world I am not sure if it is the aim of the government to destroy the recreational diving industry in Australia Many dive shops are closing in Australia not due to safety but excessive bureaucracy I personally have been a Dive Instructor since 1983 I no longer teach diving in Australia I am sure the diving industry in America is as safe or safer than Australia Its a shame we have great diving If you are interested to see what we dont want for the diving industry in other parts of the world have a look at To show you how absurd this legislation is A recreational SCUBA Instructor must have a Commercial Diver medical form a dive physician Imagine if you had a dive school like I did with 50 cylinders and they have to be hydro tested every 12 months plus an eddy flow test For reference www.worksafe.qld.gov.au/your-industry/diving-and-snorkelling/diving-laws

You should not be scraping off any of the oxidation on aluminum tank. All what will happen is that the aluminum that you expose is going to interact with the oxygen in the ear and create new oxidation that's going to preferentially eat into the aluminum of the tank. With aluminum tanks leaving it be. I'm speaking about this from the perspective of the mechanical engineer.
@scubatechkeylargo 2 ай бұрын
I strongly disagree with your statement when it refers to scuba cylinders. Cylinders are a flexible container holding 3000 psi or more, which can and have been explosive when improperly inspected. Oxidation/corrosion, “lost of metal” will lead to pitting in the alloy, a single pit measuring .06 of an inch will fail the cylinder, but an structural column with the same pit can remain in service. Please keep in mind we in the scuba industry are formally trained, I personally have 40 years of training and experience we are also regulated by, Department of Transportation (DOT) Pipeline and Hazardous Materials Safety Administration (PHMSA) Compressed Gas Association (CGA) Code of Federal Regulations (CFR) and OSHA . In addition we are mandated to have continual education and certification every 3 years. Did you know the person filling or inspecting your scuba tank must be trained and certified every 3 years? (CFR180.205) Here are some quotes from our training text to help you understand our methods. “ The primary purpose of cleaning a cylinder, whether inside or out, is to ensure all metal surfaces are exposed to the inspector’s eyes”. “The entire exterior of the cylinder must be exposed to the inspector and not concealed”. “If corrosion is found on the exterior, under the coating then the entire coating should be removed”.

125 to 150 is the acceptable range… slow drift is common Cycling the first such as turn off supply pressure purging and back on. Repeatedly cycling pressure will create a impression on the piston seat and should lock up IP.

GUESS WHAT ? just two weeks ago .... a dive shop owner freaked out when I brought my three old tanks from 1979 in for visuals and I knew two needed Hydro . He was almost in tears telling me they were dangerous and they CAN"T be inspected or filled ...So I took them to another shop and they said - we know that dive shops in Florida refuse to service the older tanks BUT...YES they would service and fill them !
@scubatechkeylargo 4 ай бұрын
I'm not surprised by the shop owner's reaction, as per DOT we can still inspect, test and fill along with visual eddy test. However in Florida we've had multiple tanks rupture and seen first hand the consequence of neck cracks. It's up to the individual shop to make that decision. Thanks for the comment.

I had a 10.4 litre 232 Bar Alloy 6061 tank (85 c.f.) fail a visual for a crack in the neck - DO NOT think that new alloys are not susceptible to load cracking, IF you leave a scuba tank full long enough it will fail at the weakest point. I now only dive steel cylinders which are looked after better than my dive computer, and IF I'm not planning to dive for 3 months or more, I leave them at 50 Bar (500 psi) so as not to put unnecessary stress on the cylinder.
@scubatechkeylargo 4 ай бұрын
Sometimes a fold in the neck can be mistaken for SLC neck crack. I've seen many shops confuse folds with SLC in 6061. I'm not saying that it can't happen but the chances are slim, an eddy current test will confirm a SLC.

Thanks for the informative video. I am here trying get a better understanding how all this works. Also I'm dabbling in a different application,. PCP for air rifles. Just purchased a carbon fiber over Aluminum tank. I have my own compressor and Have had an old retired tank laying around still holding air(Scott scba) But I will not add pressure to it at this point until I have it hydro'd (if it can be be done) The tank exterior is fine visually and I know that's as far as it goes. Reason I'm here again is Safety,. not sure if it matters, my tanks stay indoors and are not banged around. The whole 15 year thing... I'm trying to grasp,. I've seen tanks 40 yrs old holding pressure, Now that being said they could be a grenade with the pin pulled or they could last longer than I'm around(I Don't know)That's why I'm searching this information and not Just here. I'm not fond of the idea of having a hole drilled in my tank (Just Because Of A Date)and no test actually performed to justify. And I may be wrong in my thinking, and if I find that out I will change my thoughts on this. Closing thoughts: I know folks way smarter than me designed this format/platform. The other 2(TWO) factors is Safety And MONEY,. and that's what I am trying to separate if that's even possible. Now this new tank I'm getting, I will be installing the Valve and will be regularly inspecting the interior and will know how this tanks full history will be. The Scott SCBA tank I have went into burning buildings and sure it had some abuse including drops and being banged around. And again I have it Idle at this point. But it's a bit of history to me. Thank you again.

SCBA bottles are made from thin aluminum shell wrapped with carbon fiber and resin finish for strength. The lifespan of 15 years is designated by the manufacture, they believe after 15 years these bottles can weaken and no longer be trustworthy to hold pressure. These bottles easily damage, any exposed fibers is considered a weak stop. Thanks for watching... be safe.
