in this area. The condenser contains 6,084 tubes that are 7/8 OD, 0.049 wall, 303 long, admiralty brass. The plant decided to use the Eddy Current Technique (ECT) to inspect 600 tubes. The condenser uses local river water. TesTex told the plant the unit could be inspected and a color-coded tube sheet map showing the results could be
TUBE-TO-TUBESHEET JOINTS:THE MANY CHOICES Fabrication-Inspection-Testing of the Tube-to-Tubesheet Joint The fabrication of a heat exchanger involves many operations of forming, machining, drilling and welding in order to manufacture all of the parts, which are to be assembled to produce the final heat exchanger. Emphasis here is on fabricating the tubesheet, inserting the tube ends and
Condenser tube inspections are conducted with the unit online with the leaking condenser tube bundle isolated and drained for occupancy. When the hotwell condensate is contaminated due to cooling water intrusion from a condenser tube failure, it is imperative the source of the leakage is identified immediately.Images
