is a LP95 'really' 95 cft?

[keysdvr]

Two quick questions regarding a '03 Faber LP95. The tank shows 2730 psi as the fill pressure, and also has a + next to the hydro.


1) Is the tank 95 cft when filled to the psi listed on the tank (2730 psi) or only when it's filled to the + 10% (ie. 3003 psi)?


2) The tank was originally + but when it was subsequently hydro'd, it didn't get the +. There is, however, a REE number (REE 59) on the tank - is this what I need the next time it's hydro'd to again get the + again?


I've looked a couple different places regarding tank specs (including here: Scuba Cylinder Specifications from Tech Diving Limited - 928-855-9400 and Faber Industrie) but I can't find 2730 psi referenced. It's usually 2400 or 2640 (ie. +10%).


I can provide the tank serial numbers if needed. Haven't physically measured the tank just yet...


Thanks!

I assume this is my friend's tank, right? I really thought that tank was a 3AA 2400 tank; can you check to make sure it doesn't say that? I have heard of MP steel tanks, but I thought that meant 3000 +10% and I've never actually seen one. Check the circumference of this tank, I suspect you will find it to be around 22.75" which would make this tank a 7.25" diameter tank. Please post what you find, I'm really curious. If it turns out to be an 8" tank you might really have a LP95.

If the service pressure is really 2730+10%, that would bring it up to 3003 PSI with the plus, which does sort-of make sense for the scuba world. I just never heard of a tank like that, but maybe someone else knows more than I do about it.

I can tell you about the hydro situation, though. The place that the tank was last hydroed was through the same dive shop where I brought my LP72s and did not get the plus rating even though I provided the guy with the REE number. Briefly, the problem is that that particular hydro shop is terrible and I will never bring another tank to them. There's another hydro shop in San Antonio I can recommend. Absolutely you can get the plus rating next hydro if the tank passes.

Yep - it's the tank from your buddy. The full stamping is M8303 03/0429 095 (next line) 3AAM 209 / DOT-3AA 2730 REE 59. I haven't measured it, but it 'looks' fatter than a std AL80 and when I put my plate on it, I had to let the cam bands out a bunch. It's significantly shorter as well. (I'll measure it when I get home). The 2730 psi threw me - I was expecting to see 2400/2640. The LDS vis'd it and filled it to 3k - commenting that they filled it to the + even though the second hydro wasn't as such (which was pretty cool). My big question is - do I get 95cft at 2730 and ~105 at 3000psi, or 95cft at 3k (and thus only 85cft at 2730)?

Thanks for the info about the hydro place near the airport. (A-1 off of Rhapsody, right?) I plan to get it done (and push for the +) before I leave the area so that I know that it'll be done.

Well, gee, if I had known it was a 95 I would have bought it from him years ago....I believe that the 95 cft would be at 3000 PSI, not 2730.

BTW, did you see his aquarium?

You get the full fill with and only with the 10%. Thus you get the 95 at 3000psi.

Look at the metric stamp it says 3AAM 209 which means 209 bar - around 3040 psi - at that pressure th tank holds 95 cuf. Metric does not have a 10% option so thats the rated pressure.

Thanks for the info!!

Measure that tank! I'm still betting it's a 7.25", but I've been wrong about the other stuff, so maybe I'm wrong about this too.

 

[keysdvr]

Halocline - I stand corrected. It IS 7.25" in diameter. It's only 22 1/4 to the top of the neck, so still a bunch shorter than the LP80 specs (or, strangely enough, the Faber 95 tank specs). Weird.

I have 2 2003 lp95 fabers. they are marked as 2400 and 2640 with the + fill. Dont know wehre you get the 2730 from. the capacity is actual 95 at 2640.

from huron tank specs.
