ABSTRACT:
A liner (12) substantially smaller than the thickness of the tube plate (2) is inserted into the tube (8) so that, while one of its ends is in a region of the tube (8) inside the tube plate (2) and away from the entry face (2a), the other end of the liner (12) is beyond the exit face (2b) of the tube plate. Diametral expansion and roller expanding of the liner (12) are performed in the position which the latter occupies inside the tube (8).
