Check out this nicely deformed metal tube. It's from a small
power-pack, you know, one of those that have a 1hp motor, one piston
high pressure pump, relief valve and a directional valve. Normally
these packs are limited to 700 bar. This one was too (before its owner
tampered with the relief valve), as a result a brand new 1000 bar
pressure gauge and the metal tube were "gone in under a second".
It is curious that the hose and the disconnected quick coupling, which
also took the blow, held on...
Think twice before eliminating a relief valve, especially in high pressure systems.
