hydrostatic test for tanks

[vollie11]

Is there any rule/law that tanks older than 6 year are not allowed for a hydrostatic test and that you cannot use them anymore?

No, not for conventional scuba tanks. Some fiber-wrapped tanks, such as firefighters use, have expiration dates.

What he ^^^ said. I don't think I have any cylinders as new as 6 years old, and some are over 40.

but the expiration dates wouldn't disallow a tank from being hydro'd, if it is good for 15 years and you go 6 years from the first hydro it will still go through.

I have tanks that went 20 years without being hydro'd and they still take them, no problems.

I wanted to send my tanks for hydro test to the next facility, which is in Indonesia and the shop refused to test them because they were not tested for 6 years.

Ha! That is a joke.

In the US, the hydro is good for 5 years. No one should not hydro a tank because it had been 6!

My Father had wanted to dive and acquired some gear, but then never did go through with it.

He had a steel 72 that had sat in the garage for 40 years and had never had a hydro after manufacture. Just on principle, I took that tank in and had it hydro'd and I have dived with it on many occasion.



It passed without any issue

I just had a LP72 hydro'd that was made in '64 and maybe had one after the original. The last VIP was '91 and I think the last hydro may be stamped 86 or 87. Passed without issue.

I guess it's remotely possible there's some such law in Indonesia, but the complete lack of logic that would require leads me to give long odds that it's just someone stupidly turning away business.

I have an O2 supply bottle that was "born" in 1906. It's been "hydroed" a "few" times since.

You need to find out the rules for compressed gas cylinders in the country you are planning on using the tanks. Don't expect a dive shop to really know these rules, ironically. In the U.S. you'd be amazed at some of the ignorance about compressed gas cylinder use and testing. You might start by talking to someone that actually does hydrotesting; most likely that person primarily works on fire extinguishers and welding supply tanks. But hopefully you'll get some answers about the correct rule.

In any part of the world I'm familiar with, no steel or aluminum scuba cylinder would be disqualified from being tested because the date since the last test had been 6 years. In the U.S. cylinders only get tested every 5 years, in the EU the requirements are different.
