Older steel tanks?

I have a steel 72 stamped 1961 gave this one to my 14 year old daughter who just got her Ow cert. I guess it is hers now.

No way, you need to send em to me to be properly disposed of. Seriously steels as long as they pass hydro can outlive you. I have one from 53 and one from 55 along with another two from 73 and 74.

"As long as they pass hydro" is a pretty big caveat...

Here's two from 1943 dove them yesterday.

I'm jealous.

Not really. It is exceptionally rare for a steel tank to fail a hydro test, especially an older 3AA tank. Some of the newer special permit tanks have been known to fail but in the majority of cases I suspect it is due to improper testing and not following the round out procedure prior to the test.

The biggest reason a steel tank is condemned is pitting caused by rust. If a tank is properly cared for and tumbled every 5-10 years to remove any excess flash rust that may form inside it will easily last 50-100 years.

Good information for sure although the PST issue and Worthington's lack of a track record raises some concern about steel cylinder longevity. Do most LDS's properly alert tanks owners of the onset of rust? To be honest with you I have not heard much about the practice of tank tumbling until I became active on this board...

It's true that the HP products don't have the same history. I consider that a minor risk since I fnd them to be an excellent combination of size, weight, buoyancy and capacity.

As part of the VIP process the local shop will touch them up with a brush. Sometimes NC, sometimes for a minor fee. I haven't had anything that needed a tumble, yet.

Yeah, my Worthington HP100's make diving a pleasure. The same with my Faber LP85's doubled up. Thanks for the info...

I think I just ran into the oldest still being used SCUBA tank that I have ever seen. This tank has been in almost regular use for SCUBA since WWII and for it's original use for a while before that. I couldn't read the original hydro date because of too much paint but the oldest readable date was 7-41 and there were four hydro stamps before that.:shocked2:

The neck was almost full of stamps. I counted at least 15 hydro dates and at least 6 of them had + after them. It was a ICC3A2015 tank that I would guess was about 44CF.
