| titleOfInvention | Method and apparatus for positioning and expanding tubes in tube plates |
| abstract | Three elastic members 12, 11, 5 are placed in a tube 2 to be inserted into a tube-receiving bore in the tube plate 1. A rod 6 is pulled to axially press the first elastic member 12 so that the same is expanded radially outwardly into frictional engagement with the inner surface of the tube. The rod 6 is further pulled to axially move the tube by means of the frictional engagement between the first elastic member 12 and the tube. This movement occurs as the second elastic member 11 is axially contracted and is stopped when the tube-end engages a tube positioning sleeve 10 and bushes 15, 16 pressurising the member 11 come together with the member still clear of the tube-wall. Continued movement of the rod 6 expands the third elastic member 5 whereby the tube end is radially outwardly expanded into intimate engagement with the inner surface of the bore. <IMAGE> |
