A method of tubing manufacture comprising forming a tube (10) having an internal artifact (13) 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 (D1) 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 (Rl) of the adjacent inner surface, and forming a single flare on the end of the tube. |
