Anyone know if a hydrostatic test date on a steel tank lasts 5 years or 10?
I've got someone claiming its 10 for steel and 5 for aluminum.

At my last refill at Praxair, I complained about 6-year-old stamps, and
they assured me it was 10 years for CO2 in aluminum. When I researched the
actual federal regs, I couldn't decode what they were saying. It may be
that the regs don't say clearly, so some say 5 and some say 10.

Yep. Like others have said, if you're swapping out and you give them one
they consider past due, they just get it tested. No mater if their policy is
5 or 10 years, they shouldn't give you one that doesn't met their standard.
And by no means should you accept one that is older than 10 years.

I don't quite understand your last statement. Are you saying if a tank
is more than 10 years old it should not be used? Are you saying if a
tank is more than 10 years out of date it should not be turned back in
for recert?
I've had tanks more than 10 years out of recert and exchanged for new
ones without issue. Also I once had a tank that was older than I am and
a coworker got one in cert that was from 1977.
Cheers,
Mike

A friend of mine was given a steel 50lb CO2 tank a couple of years ago.
Still had CO2 in it so he ran it dry. When the subject of refilling it came
up I looked at the certification date. The most current was 1982. The
oldest cert date was 1933! It had 10 0r 12 other cert dates stamped in it.
The local welding supply generously disposed of it for him at no charge.

I could have swapped it at my local place and it probably would have
passed cert. I'll bet that is what the welding place did...it saved them
$50 on another tank...;)

I couldn't tell from Dan's original post if he was concerned about receiving
one that was past it's test date or worried about turning one back in. What
I meant is that if he were dealing with a shop that swaps out tanks and
insists it's a ten year period, he shouldn't accept one from the business if
it hasn't been tested in the last 10 years, or for that matter any serious
visible concern for the tanks integrity like dents, bent valves, or severe
rust.

Someone is trying to sell a tank saying its got a 2004 test date and is
good for 10 years. Somehow I doubt that will fly around here where places
say 5 year dates. I have a place that swaps and a place that fills, swap
is about $6 more expensive so I do that when the tank has expired.
The reason I asked was try and understand why this person would say 10 years
when I had thought it was 5 years no matter what.. sounds like its one of
those gray areas.

Maybe he works around fire fighting equipment? Someone else mentioned it and
I seem to recall the 10 year mark for extinguishers when I had to be
concerned with that in the USCG

I saw somewhere advertising for new tanks with a ten year date. It
might be ten for the initial period and 5 on subsequent renewals maybe?

Man, this *ought* to be easy to find. I bet if someone took the time to go
through docs at DOT it'd be there.

I found some info that suggests that for CO2 tanks used as fire
extinguishers, it's 10 years for a new tank and then every 5 years
after that. For non-fire extinguisher tanks (what we use) it is every
5 years.
This link is someone summarizing the US federal regulation which deals with
it (apparently it's a very complicated code).
http://fins.actwin.com/aquatic-plants/month.200410/msg00264.html
Also, the rules are different if you're outside of the USA (not
surprising). A poster in the same thread linked above indicated that
it was 10 years for a new tank in parts of Canada.

I trade out my tank at a place that doesn't care what the date is, so
neither do I...;)

Hey... I said that somewhere back there. Maybe that's why I didn't scour
those docs. (grin)

I exchange my tank so it doesn't matter. I think it is the same as air (as
in SCUBA) tanks which is 5 yrs., regardless of material.
