I can't stand it. I have to relate this story. We were filling tanks on
the beach one summer (in the shade), using a Bauer compressor and a 4 way
manifold (ie; filling 4 tanks simultaneously) when a burst disk in one of
the aluminium tanks let go. The offending tank could not escape, since it
was attached to 3 other tanks and the compressor, so it dug a hole in the
beach 5 feet deep and about 15 feet across into which the compressor and all
the tanks rolled, by which time the compressor stalled and the sandstorm
abated. Very impressive to watch.
Suspecting corrosion of the burst disk we made it a policy to change the
damn things every hydro test. Even that didn't stop one letting go while I
was filling a tank in my shed one night. The blast of air blew everything
in the roof space to the ground. I haven't had any trouble like this lately...
