Scuba Forum / General / June 2005Scuba tanks transported to high altitude
Is there any danger in transporting scuba tanks filled to 3000psi at sea level to an altitude of 10,000 ft in a car? Does it weaken the tanks or have any other ill effects? What about the risk of rupture? No. > Is there any danger in transporting scuba tanks filled to 3000psi at > sea level to an altitude of 10,000 ft in a car?

Dunno what it is at 10,000 ft., but in space it would be zero. The tank isn't going to notice 3015 PSI any more than 3000 PSI.

Must be O2 clean for Nitrox tanks. Curtis > > Is there any danger in transporting scuba tanks filled to 3000psi at > > sea level to an altitude of 10,000 ft in a car?

An old car inner tube would work just as well. But seriously, how do you O2 clean an old truck inner tube to make it nitrox tank ready? -- Randy F.

Making sure, of course, that you buy the old truck/car inner tube from an LTS (local tire shop), who acquired their inventory through the proper channels. Not from from some Internet shop that might sell you a gray market inner tube without a proper US warranty. > VIP it, label it, and dye it green? > > Making sure, of course, that you buy the old truck/car inner tube from > an LTS (local tire shop), who acquired their inventory through the > proper channels.

An old car inner tube would work just as well. Absolutely incorrect. Car tubes are not the same grade of rubber they use for higher pressure truck tubes. Must be "E" series tubes. > But seriously, how do you O2 clean an old truck inner tube to make it > nitrox tank > ready? Only the LDS can perform the magic. Just put another dollar in their registers. Curtis >> > What about the risk of rupture? >> [quoted text clipped - 5 lines] > tank > ready?

What about the risk of rupture? Your biggest risks are going to be being involved in an accident, or exposing the tanks to extreme heat (eg, hot trunk, but these risks aren't unique to altitude...merely vehicular transport. The ~5psi change is pragmatically negligible, but do feel free to bleed 5psi out of your tanks if (a) this makes you feel any better, and (b) have any way of accurately measuring this [unlikely with scuba gages]. -hh |
