Rolling tubes in tube sheet
WebExpanding the center tube sheet can be challenging, regardless of the installation method. This is largely due to the long reach required to get to the center tube sheet. Generally, most chillers have about 10 – 15 ft of space from the front of the vessel to the center, resulting in custom tooling and a challenging set up. WebFailure to achieve adequate rolling was documented with ID tube measurements in the tube sheet, and the ease with which the tubes could be removed from the double grooved tube sheet (Figures 1-4). The second incident was on a sulfur dioxide gas unit and involved problems with replacement of the tubes and tube sheets in an old unit.
