The failed tube had to be removed in short sections at the smokebox end. Each section was about 4 to 6 inches long. The first section was pushed through by pushing from the firebox end. This piece was cut off, and the next section pushed through. This piece was cut off ...........
This photo gives an idea of where the failed tube is. Two superheater elements have been removed to give better access. The failed tube is at the top - you can see where water ran down the tubeplate during testing.
These photos show Carpo in the cramped condition of the smokebox, cutting sections off the tube.
The tube had to be cut into more than 30 sections to get it out.
Many thanks to everybody involved.
