Senior Flexonics Pathway Repairs Turbine Crossover for Delmarva Power and Light

During the fall turn around at Delmarva Power and Light’s Edgemoor station, a leak was discovered in the crossover duct on the west turbine. Senior Flexonics Pathway was called and an engineer was dispatched to the site to investigate the extent of the problem. Water vapor had seeped through the first ply in the ply testable bellows originally supplied by Zallea Bros. for Westinghouse. Repeated start ups since the leak first began had caused the inner ply to implode when the accumulated water between the plies turned to steam. On Senior Flexonics Pathway’s recommendation, the crossover was sent to the Senior Flexonics Pathway facility in Oak Ridge for expedited repair.

The bellows were designed to be exactly like the original equipment. The original root rings were reused to save time in fabrication. The crossover expansion joint was a pressure balanced elbow with inside attachments. A drawing was not available; therefore, the unit had to be taken apart and measured to determine the actual bellows dimensions before fabricating the new bellows.

The turn around of the crossover took 3 weeks in Senior Flexonics Pathway’s Oak Ridge facility. All work was completed on schedule.
