Vno Posted February 1, 2019 Report Share Posted February 1, 2019 Does anyone have a suggestion for getting a Hydro test done on a portable O2 bottle that is due. Precise Flight Aluminum bottle. If it matters I am located in the Northeast US and would prefer local to shipping. Brian Quote Link to comment Share on other sites More sharing options...
smccray Posted February 1, 2019 Report Share Posted February 1, 2019 Call a local dive shop or a medical oxygen supplier and ask them where they take their tanks. It's a DOT reg not an FAA requirement to hydro test, so any test is fine. It doesn't have to be an aviation vendor. 2 Quote Link to comment Share on other sites More sharing options...
Steve W Posted February 1, 2019 Report Share Posted February 1, 2019 Also, check with your local industrial gas/welding supply places. (Airgas, Praxair, etc) 1 Quote Link to comment Share on other sites More sharing options...
Yetti Posted February 1, 2019 Report Share Posted February 1, 2019 I often wonder about the most random things. What are the odds of a cylinder failing the hydro test? is one of the things I have been wondering. This thread helped. https://forum.millerwelds.com/forum/welding-projects/34638-cylinder-age-limit Quote Link to comment Share on other sites More sharing options...
VetRepp Posted February 2, 2019 Report Share Posted February 2, 2019 I get mine done at a Fire Equipment Distribution company - If there is something similar in your area - worth a call - Dramatically less expensive than thru an A&P. 1 Quote Link to comment Share on other sites More sharing options...

I’ll second the fire extinguisher guys. Went to Keene who is a big gas supplier around me and they said they use a local fire extinguisher supply company.

carusoam Posted February 2, 2019 Report Share Posted February 2, 2019 The tank test is measuring elasticity of the materials... Inflate it, see how much it expands... and how evenly it expands... Most materials lose flexibility over many cycles and years... why and how depends on the materials of construction... Steel seems to last the longest, aluminum a bit less, Super light composite materials a world of their own... In some cases... LBs... the built in tank is resident in the same compartment with lead Charlie weights... Depending on how many CWs are back there, a less high tech tank might be a better solution... depending on the owner... Pp thoughts only, not a mechanic...

Brian My local welding shop charges $25 for hydro testing, and refills a D size cylinder for about $12. The only downside is that every guy who works there admires the shiny oxygen bottle and kind of caresses it while telling me I have such a nice looking cylinder. It's a little unsettling. Just make sure to remind them it's a CGA-540 valve, and that it's not for medical use. Quote Link to comment Share on other sites More sharing options...

Since then have move onto a 3 tank supply system that 4 of us are participating it. Much more convenient having our own access.

Since then have move onto a 3 tank supply system that 4 of us are participating it. Much more convenient having our own access. I keep 2 size D cylinders, enough for 2 people for 5-6 hours each. I just drop them off and it takes them a couple days to send down to their plant and back. For $24, I'm willing to pay someone else to deal with the headache. I can see it being worth it with a few people participating, but it's just me. I've mentioned this before, but you can get oxygen tanks from medical suppliers with those nice straight-valve CGA-540's with integrated pressure gauges, which is pretty much identical to what you get from Aerox, for about $90 Quote Link to comment Share on other sites More sharing options...
