Hi friends: You are putting yourselves in great jeopardy by testing the pressure tolerance of 55 gal drums with air! For God sake, don't you do it.
Testing can be accomplisehd with a small water pump that can raise water pressure sufficiently, probably 30 lbs will be enough to burst the drum. Do not allow any air to be compressed within the drum, make sure all air is purged. Only water should fill the tank. I can not conceive using an ordinary 55 gal drum in any process that requires air under pressure. That is a sure way to get into a big trouble.
