FlyDave Posted March 5, 2014 Report Posted March 5, 2014 The built in o2 bottle in my Bravo is due for hydro by the end of the month. I had a place in Santa Rosa (15 miles north of my airport) hydro test my portable medical bottle. I know I have to take the bottle out of the airplane to do this but can that same facility hydro test the bottle from the Bravo or does that have to be done by a "Aviation" oxygen facility (not sure there is such a thing). Thanks, Dave Quote
N201MKTurbo Posted March 5, 2014 Report Posted March 5, 2014 They should be able to. I use thunderbird cylinder in Phoenix. They can hydro test anything. The hydro test is a DOT requirement not FAA. Quote
triple8s Posted March 5, 2014 Report Posted March 5, 2014 If your tank is Kevlar (fiberglass) be VERY careful removing it, carrying it, transporting it, reinstalling it! Any scuffs or scratches and you'll be buying a new one. I'd lay blanket under it in the belly before I started removing the straps. Quote

Guest Posted March 5, 2014 Report Posted March 5, 2014 Don't forget that if your oxygen cylinder is of composite construction it has a 15 life limit from the date of manufacture as stamped on the label. Clarence Quote
Piloto Posted March 5, 2014 Report Posted March 5, 2014 Scuba Dive Shops also do the hydro tests on tanks of the same size as yours. Check with them. José Quote

DrBill Posted March 6, 2014 Report Posted March 6, 2014 I had my portable bottle tested early last year. It's interesting how they did it. I had it done at a Fire Extinguisher refil shop called Simplex-Grinnel. They put the bottle in a tank filled with water then pressurize the bottle. They measure how much water is pushed out of the tank due to the growth of the tank due to the pressure ( I think it was 3000 psi). Then they remove the pressure and some water is sucked back in the tank. The water that is left is measured and that has the limit indicating that the bottle expanded and then contracted but not back to original size. BILL Quote
