from mine knowledge, tanks have actually "re-hydro dates" since you must make certain the covering itself is still solid enough to host the hefty pressure being placed inside. Its every for safety. More recent tanks space 5 year from the date on tank and also i believe its after ~ 11-13 years the the tank need to be tossed.(dont quote me on the last part) yet ya for safety reasons and also no..if a tank is apparent old and also worn..DO no FILL IT

Think it could be 15 years and also toss it, 11-13 would more than likely be much safer though, but you got it, its basically to test the truth of the tank under high pressure. As soon as a tank is hydro tested they fill the tank v water (obviously, hydro) come a PSI over the max push of the tank (not sure exactly how much over) This basically causes the tank to swell and also the tank itself will certainly actually obtain a small bigger. Throughout this phase any kind of weakness in the tanks truth should cause it to have actually a blow out and also the tank will rupture. If nothing happens then the tank will be deemed serviceable and also will get your ugly new label epoxied top top the tank. (this is just how it was described to me at my neighborhood place, hope its accurate.)

Pretty much, alot the what AHFellows said. Remember, wait tanks take it in air, and hold it at a high pressure. Usual pressure the the air about you is something prefer 6 PSI. So once you to fill a tank through air, at 100 PSI, you space filling it to take care of something that is currently at a higher pressure than whatever else roughly it. Fill it come 3000 PSI, or 4500 PSI, especially on a consistent basis, and you have to make certain that the tank deserve to handle the pressure.Hydro tests, done every three or 5 years, room there come make certain that the tank deserve to handle the stress, overload of gift filled regularly, as well as emptied. Yet carbon fiber and fiberglass tanks have the right to only manage this for so long. Therefore they have a 15 year lifespan. Anything ~ that, one would danger failure of the contents and feasible catastrophe. Stole tanks have the right to last up to 24 years, prior to they space no much longer structurally sound. Aluminum tanks though have the right to last forever, as lengthy as they happen their five year hydrotests. Honestly, if one can get a 68/4500 tank in all aluminum, without it weight a tone, and also not gift overly huge in size, that would certainly be pretty cool. Purchase one, and also other than the hydrotests, it would last friend forever.That is if friend still beat after 15 years...
