No markings on Tanks

[tyesai]

Right now I'm looking at buying some Roth steel tanks. The thing is is that I noticed no identifiable stamped markings on them. I currently live in Spain but I was wondering if this would be a problem when I get back home to the States as far as getting them filled or I can I just get the tanks re-inspected and call it good.

These are the ones I'm looking at.

Are you buying the ones in the link? If so there are marked clearly and this can be seen in the photos. Or do you mean you are buying tanks like the ones in the link and but that have no markings?

As for forign tanks, make sure it has DOT (US Department of Transportation) stamps. If it does not I would bet that no one in the US will fill, viz, or hydro the tank since it has none of the indentification they will be looking for when they check the tank.

The ones I was looking at in the store have no markings on them. They are made by a French company and have been imported to Spain, I looked all over the ones at the store and didn't see any identification type stamping. It isn't like they are a great deal or anything, fair, about $300 depending on the coversion rate for Euro's to Dollars for a 12 liter, $320 for a 15 liter. I don't have my heart set on them, it would just be convienient as I wouldn't have to deal with the shipping but if it turns into a PITA when we go home, I'll just get some AL 80's from the states shipped to me. Amazon is my friend after all.

Getting tanks with air is either expensive or a PITA for me. The dive shops have them for rent for 20euro's, or I know I guy that I can get them from for 5euro's but I have to play phone tag with him and I'm not completely satisfied with his air source. If I have my own I can get Decatholon to fill the tanks for 1euro and they have regular store hours.

If they don't have markings they will be useless in the USA.

Best off to order your tanks made by a US source and your worries are over. $300 won't seem like a bargain if you can't get them hydroed or filled.

Roth tanks are made in France and are normally stamped/marked (this is mandatory for the same reason than in the USA, namely tanks under pressure can explode; BTW they do explode sometimes because of poor maintenance). But the marks are not the same than in the USA.

If the tanks you're talking about are really not marked (and then how do you know these are Roth tanks ?) forget about these tanks : don't buy them and don't even use them.

American and Europeans norms for the threads of the valves are different (not the same units) as far as I know. Screwing the wrong valve (eg an US valve in an European tank) in a cylinder is sometimes possible, but life-threatening.

If you plan to live or stay long in the USA, buy your tanks in the USA once you'll be there. If you buy tanks in Europe for use in Europe, sell them in Europe when you leave Europe for the USA.

The shop I work in here in the US has turned down tanks for fill from both the UK and Australia. Both had proper markings but lacked DOT approval, making it illegal for a US business to handle (unapproved alloys or manufacturing techniques in US). In Egypt I ran into tanks with completely different markings... a tank with no markings what so ever sounds suspicious..... might not be as good a deal as you think....

Never had a problem with tank threads in Europe, maybe more of a regional problem.....

You could purchase your own compressor and avoid the fill problems, but this is an expensive short term fix (no one in the US would hydro those tanks either, again non "approved" alloys and such).

Just an opinion, but I would pass on this deal if you are to be returning to the US shortly, no markings on the tank is a red flag for me..

Good Luck

Thanks for the info on the markings, but is a yoke valve not a yoke valve?

Are you talking about the metric system for the threads on the valves?

Thats exactly what I was concerned about, I'm not about to buy a compressor, I guess I'll just get some mailed here. I'm not concerned that the tanks are "bad" in anyway because of the lack of markings, I was just concerned that I'd drop $600 and then have nothing to show for it in two years when we come home.

Thanks!
