Abstract (en)
[origin: EP0180892A1] 1. Device for electropolishing the inner surface of tubes with an electrode connected to a direct-current supply able to be inserted into the tube to be electropolished and extracted again, the electrode (18) enveloping a tube-like body (20) metallically conductive on its outer surface, able to be connected to an electrolytic supply pump (50), which body carries, on its front end in the plugging-in direction, a stopper (21) sealing in a liquid-tight manner the tube (5) to be electropolished, is equipped in the vicinity of the stopper with at least oen outlet opening (27 to 30) and is guided in an axially displaceable manner on a supporting frame (12 to 17) characterized in that the supporting frame (12 to 17) is able to be anchored on the tube plate (1) of the heat exchanger (2) for electropolishing heat exchanger tubes (3 to 6) and that a return motion casing (41) encasing the electrode (18) is guided in a fluid-tight manner on an adapter plate (13) of the supporting frame and is pressed by way of a spring (42) supported on the supporting frame (12 to 17) with a mouth piece (43) against the tube plate (1).
