  • Apparatus for vertically tubing a heat exchanger
    Patent number: 4319725
    Abstract: A support framework for a double column of U-shaped tubes of a heat exchanger for vertically suspending the tubes above the heat exchanger during a tubing operation is shown. That portion of the framework which supports the U-bends of the tubes is primarily used to support the tubes above the tubesheet and lower the tubes into the tubesheet as a unit. The U-bend support framework includes a vertical member in which the separate tubes of the double column are clamped to normally prevent movement of the tubes therein and also permits individual release of the tubes when necessary.
