    It’s done every single day. No one has blown up yet. This has been going on for at least 20+ years that I’ve been witness

    I only take mine to 3900 or so, NEVER to 4000. My garage is safe.

    I lost my garage in the great flood of 2017. I haven’t rebuilt it yet. Filled it with 5’ of water. So... currently all my tanks are in my dining room. I hope my dining room is safe. :)

    I know. Me too.
    See the “great flood of 2017”. It was actually a hurricane. :)

    I would be apprehensive about filling this, hyrdo date, vis date?

    It took me a bit to get around to digging this up and I don't think the original text from OMS is anywhere to be found on the internet. Maybe someone on here has a hard copy of the old catalogs?

    From the "Oxygen Hacker's Companion":

    "OMS, which sells Faber LP steel tanks, notes in their catalog that the tanks are rated for 2640 psi (2400 psi Plus the "+", 180 bar), the test pressure is 4000 psi (275 bar), the minimum burst pressure in excess of 6400 psi (440 bar) - and then casually mentions that Faber rates the tank for 10,000 fill cycles at 4000 psi (274 bar)! That's the equivalent of hydro tasting the tank every day for 30 years."

    Nothing like getting rid of the swastika with a cold chisel. I've seen a few of those tanks over the years.
