1. A single expanding cone is revolved around a longitudinal axis of a pipe to be machined and is rotated about a central axis of rotation of the conical body so that a conical surface of the conical body is connected to a pipe end portion. In the method of forming a flange portion on the end portion of a pipe by pressing the pipe, in the first step, the center of rotation of the cone is adjusted so that the conical surface forms an angle of 35 to 40 ° with respect to the longitudinal axis of the pipe. After the shaft is installed and the end of the pipe is expanded, in the second step, the center axis of rotation of the cone is moved so that the conical surface forms an angle of about 90 ° with respect to the longitudinal axis of the pipe.
