  • Patent number: 4747373
    Abstract: A method and apparatus are disclosed for substantially eliminating flow induced vibrations of the flow tubes of a steam generator in the U-bend region. Antivibration bars are provided between columns of flow tubes in the U-bend region which are contoured on one side to correspond with the exact as-built and as-bent diameter of the tubes as located within the tube bundle. Measurements of the actual flow tube diameters are made and recorded and stored either on tape or in a computer which is then used to control a numerically operated machine which configures or machines cutouts in the antivibration bars to precisely correspond with the respective measured diameters of the flow tubes. Only one side of the antivibration bars need to be machined because of the flexibility of the flow tubes which allow the positioning of the other side of the flow tubes along a flat plane.

  • Patent number: 4665866
    Abstract: An improved, grid-type flow distribution baffle for both providing lateral support for an array of heat exchange tubes and for generating a sludge-sweeping water current within a steam generator is disclosed herein. Generally, the improved baffle comprises a plurality of grid members for defining an array of square, tube-capturing cells, wherein each wall of the cell is closely adjacent and contactable with the side of the tube. Each of the cells is circumscribed by a flange at one of its ends which includes a substantially circular opening for allowing the tube to extend through the cell. The flange includes four flat portions spaced apart for rendering the flange flush with the center portion of each of the square walls which form the cells of the baffle. These flat portions allow the flange to closely circumscribe the tube without coming into contact with it, thereby avoiding "point contact" between the flange and the tube.
