This engined system cuts pipes (A) using the pressure of the centrifugal force on a blade (F) which rotating cuts into the pipe (A) until it is completely detached: such system reduces considerably the dimensions of the cutting device. As an indicative but not restrictive example let's consider the case of counterweights (I,H) of about gr.250 each which can rotate at a speed of about 3000 revolutions per minute powered by an electric motor of only 500 watts. In these conditions an half-inch zinc-coated steel pipe can be cut in 5/7 seconds. The reduction through-put time and in the consuption of energy is self-evident. <IMAGE>
