A method of making a tube having an expanded region which includes the steps of providing an elongated metal tube, preparing the tube to be expanded, and, exerting a generally uniform outwardly radial force to create the expanded region. During the preparation step, a region of the tube is annealed

A method of making a tube having an expanded region which includes the steps of providing an elongated metal tube, preparing the tube to be expanded, and, exerting a generally uniform outwardly radial force to create the expanded region. During the preparation step, a region of the tube is annealed by applying heat. The outward radial force may be created by pressurizing the tube, by freezing water within the tube or by axially rotating the tube.
