Abstract
An apparatus for expanding and belling a tube is provided including a receiver for supporting a first end of the tube. A stripper block assembly orients a second end of the tube along an axis. The stripper block assembly includes a first grip and a second grip movable in and out of engagement with a surface of the tube. The apparatus also includes a movable belling tool axially aligned with the tube. The belling tool bells a desired length of the tube and supports the second end of the tube. An expander tool is arranged to pass through the axially aligned tube to expand the tube. The expander tool includes an expander rod and an expander bullet. A portion of the expander bullet has a diameter larger than the diameter of the tube.
