Abstract

An apparatus and method including a swaging die (10) with an internal cone-shaped bore section which will swage a pipe (14) forced into such die and form the cone section (30) on the pipe. Within the swaging die (10) is an insert/ejector plate (32) of a diameter to fit within the bore of the pipe (14) and wherein high pressure fluid directed through the insert/ejector plate (32) to the inside wall of the pipe (14) expands the pipe thus forming a longer, more acceptable, cone section (30) capable of providing more thread length for later threading operation. After the expansion pressure is relieved, the insert/ejector plate (32) is used to force the pipe (14) out of the swaging die (14).
