Check out this nicely burst metal pipe. It came from a small power-pack - you know, one of those that carry a 1hp motor, a single piston high pressure pump, a relief 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" as soon as the "user" hit "play". It is curious that the hose and the disconnected quick coupling, which also took the blow, held on...
Think twice before screwing with a relief valve, especially in high pressure systems!
I do apologize for the picture quality - the pics were made a long time ago with an old Nokia cell phone, and apparently, the lens was covered with oil too, which has always been the case with 100% of my phones, for some reason...
