Question Small dents in Aluminum 80 - Can it get condemned?

[galodoido]

I bought a couple of used Aluminum 80s and I am about to send them for Hydro/VIP. I just noticed one of them has a few tiny dents:

Is there a chance the tank will be condemned?

If the dent is deeper than 0.06 inches, likely. But from the photo it looks OK.

Yeah, but .06 is also very small. I wonder how they measure it. I also noticed some of these tiny dents in one of my other tanks that just passed hydro. So hopefully it is ok.

A chrome-plated 1.5" hexagonal brass block with 6 machined groves which can be used to estimate the depth of pits in dive tank walls. Slots ranging from 0.01" to 0.06" deep can be used as a reference after the depth of the pit has been probed.

Highly unlikely that won't pass hydro. Many hydro stamps are deeper than that.

Pit gauge is used to estimate the depth of pits on the interior of a cylinder. For those on the exterior I use a caliper.

While it may very well pass hydro, comparing to a stamp makes no sense. There’s a reason why all the stamps are on the "shoulder" of the tank. Much thicker up there than on the side wall.

The tape measure markings are 1/8" or .125". The width of the dent looks to be half that, about .060"
As long as that mark is wider than it is deep, it should pass.

Ya pays yer money and ya takes yer chances! It passes hydro or it doesn’t, nothing you can do. No sense stressing over it beforehand.

Looks fine to me though, I’ve dived worse.

The re-tester should be willing to give you his opinion on those defects before performing a full hydro-just ask.
