Drew Sailbum once bubbled...
For high pressure cylinders, the importance of a proper design should be obvious. Unfortunately, some ignore this common sense safety precaution and rig up other pressure vessels for use as a bank. A couple years ago one of these systems (an old military bomb casing) exploded at Parrot's Landing here in Cayman killing one worker.
:wacko: Are you serious?!? :wacko:
Who would have thought to use a military bomb casing to hold compressed air? That's just... well a :boom: of an idea! (corny pun fully intended).
The point I was trying to make here is that the design of a tank has a lot to do with its intended working pressure, the abuse it needs to take and such -- not all cylinders are created equal!
