Abstract
A method of tubing manufacture comprising forming a tube having an internal artifact projecting radially inward from a tube inner surface, retaining the tube in a fixture, broaching an end of the tube to remove a longitudinal portion of the internal artifact which longitudinal portion is less than a total length of the tube, finishing the radius of the internal artifact so it is substantially equal to a radius (R1) of the adjacent inner surface, and forming a single flare on the end of the tube.
