    Oooh yes.

    I've had a couple of expansion Chambers open up stress fractures under 500psi and it no big deal, just a little spurt of the water and immediate pressure drop.

    Haven't had it under air yet... I often purge the pipe with argon first as well in case the gas torch tries to set anything off.

    Same with dive tanks and such. Water was ever incompressible.

    Incidentally the guy testing my CO2 bottle told me that if a tank fails the engineers say that it "lost its structural integrity." While absolutely correct, that does seem such an understatement.

    Supposedly the alloy fire ex ones often fail first time, then the stretch is taken out, they test fine the next time.
