Abstract

The method comprises the steps of inserting into the end to be reduced a mandrel of an outside diameter coextensive with that of the bearing to be inserted and of a length coextensive with the predesignated length of the reduced portion. It then involves placing the pipe together with the inserted mandrel into a split die having a first portion of a length coextensive with that of the predesignated reduced length of the pipe and of an inner diameter coextensive with the predesignated outer diameter of the pipe. A second portion of a diameter is at least coextensive with the original diameter of the pipe. The dia and the pipe are placed into a press for compressing the pipe end by use of the die and the mandrel.
