Date Jun. 19, 1986.A method of cutting a piece of pipe from a length of pipe in a cutting plane by gripping the length of pipe directly adjacent the cutting plane and displacing the piece of pipe with respect to the length of pipe in the cutting plane, comprises applying a radially outwardly directed and a radially inwardly directed pressure against the length of pipe and the piece of pipe in the cutting plane and at both sides thereof, simultaneously applying an axial pressure, the pressures generating a stress amounting to at least 70% of the yield point of the material of the pipe, and maintaining the pressures during the entire cutting operation. A device for carrying out this method is also disclosed.
