Abstract: A mechanical tube expander including a cage having rollers mounted therein and a tapered mandrel to coact therewith for expanding the tube. A locking member permits movement of the mandrel a predetermined distance after the rollers make initial contact with the inner surface of the tube, thereby causing a predetermined expansion of the tube.
