Abstract
A curved structure (20) with two flat side flanges and a curved bottom (23') connecting the flanges, each of which is associated with a curved guiding slide (24a,24b)is used for lining a peripheral tube of a steam generator. A trolley (21) having wheels (25, 26) interacting with the guiding slides moves in the curved structure and is guided along the inner wall of the water box of the steam generator. A rigid roller-expanding tool (24) is connected to a drive mechanism carried by the trolley by a flexible cable, and is guided by a guiding device after it leaves the curved structure.
