Discoveries during Development of the next generation Ultrahigh Pressure Water Jetting Machines

Tron-Halvard Fladby, M.Sc. Mech. Eng. In todays society we often take it for granted that the technique have come so far in development that there are only room for marginal improvements within 2-10 %. You will therefore, I expect, also be quite surprized when you see what can be discovered even within relatively common technique where so may have worked with in years. That we have found new improvements that can contribute to a increase in efficiency of fabulous 300 til 500 %. Yes, you read right. This incredible but still true perspective one should perhaps also keep an open mind for elsewhere. In connection with development of Speeders new compact ultrahigh water jetting machine we made two epoch-making discoveries. In order to make optimum lances and nozzles we made close studies of the jet movements. It may immediately seem a little unnecessary to evaluate this more closely because it is easy to take for granted that some of all the others that have worked with ultrahigh pressure water jetting had analysed this carefully to get the outmost out of the equipment. But it is impossible that anyone of them can have done so when you see what we have discovered. The discoveries are very important because all the equipment in use when water jetting have only one purpose; To
