Abstract

A swaging tool is configured to drive the swage up a ramp until a series of dogs engages the inside wall of an outer tubular member. At that point the swage will be at the necessary position on the ramp to adequately expand the inner tubular for a proper supporting relation to the outer tubular. If the inside diameter of the outer tubular is at the high end of the tolerance allowed by API specifications, the diameter of the swage is increased to compensate. Similarly, if the inside diameter of the outer tubular is at the low end of the tolerance range of API specifications, then the dogs make contact with the inside wall sooner and the resulting diameter of the swage is necessarily smaller.
