Titanium scuba tank

[BIG Tiggz]

Yeah I know this is a James Bond kind of question but...

Giving that price is no matter, I have not been able to find anything close to a titanium tank. I know that making it would be very different then normal tanks but I have a bad back and need light weight.



So fire away on this topic.

Are you a TROLL??

These tanks won't work with PP if you want NITROX!!

Not to mention the difficulty in making them, and who the hell could afford one or more??

Cousteau used Ti tanks for a while. One issue with Ti is that it is extremely notch sensitive, so if it was to get damaged in any way shape or form, that notch would become a stress riser. I believe I read that one of Cousteau's tanks did explode.

Carbon wrapped aluminum is extremely lightweight, but very buoyant and you'd have to wear a lot of lead to sink.

Buy a rebreather if you want lots of gas with low weight, it's likely the best option, and would be WAY more afforable than Ti tanks.

Well... if you can bling an iphone or ipod and charge ridiculous amounts of money for it.... there's gotta be SOME super rich fellow that wants a custom bling tank!

Anything lighter than Al would be counterproductive. An Al 80 near empty becomes positively bouyant and therefore requires that you add lead to keep it down. Getting the tank lighter means you need more lead.

Potentially, given the strength of Ti, it would be possible to make a super high pressure tank (maybe 10k psi) and that would allow for the possibility of a 100cf tank the size of an al30 that might have favorable bouyancy characteristics, but there aren't that many 10k psi compressors out there.

Cousteau's Ti tanks were 5ksi 20 or 30 years ago, pretty impressive all things considered.

Bling isn't meant to be pressurized to 3kpsi and used in rough environments. In other words: filling an iphone to 3k psi and using it underwater will destroy the iphone.

As also mentioned, when iphones are dropped they do not suddenly become an explosion hazard, whereas a nicked titanium tank might. Finally, using an iphone does not require that the user wear any more lead than the user of any other phone.
