Aqua,
I'm not arguing with you. You have an opinion. I have an opinion. Playing devil's advocate is not arguing. It is presenting the other side.
My OMS/Fabers are stamped 2640. My friends are stamped 2400. My calculations are correct for my tanks.
If a tank is going to explose at 3000, then why not hydro it for 3000, or 2900? A lot of tech shops don't agree with you. I'm sorry, but that is the case. You don't have to dive with me. You don't have to even go on the same boat. But I suggest that if you are concerned with everyones pressure in their tanks, that you ask them if in cave country or wreck country before hand.
BTW, my tanks will get hydro'd every 2.5 years instead of every five. I fill them to 3000 about 52 times a year. They will get visually inspected every 6 months, and the valves get OH'd at this time. I've never had a steel tank that failed any of these procedures. When I sell them, the buyer beware. I let them know that the tanks were overfilled. I also let them know that they were inspected much more often than required. If they are not educated on the filling specs, then they shouldn't be buying tanks. It is not my liability. I took care of maintenance. It is their decision whether to use them or not.
People drive their cars over the speed limit all the time, sell them, and then stuff breaks. Are the original owner liable. No.
Again. I'm not arguing. I stated the facts about my tanks. You say I don't understand what I'm talking about. That's pretty harsh. Be nice. No one is attacking you.
