FLANGING UNIT FOR STORAGE WATER HEATER

摘要

The aim of the invention is a flanging unit (1) of a storage water heater comprising a flange (11) for supporting the heating and safety unit thereof, a counter-flange (12) stiffly constrained to a cap (2) of the water heater and a sealing element (13) interposed between the flange (11) and the outer surface of said cap (2). In particular, threaded bushes (3) are placed and constrained on the counter- flange (12), through plastic deformation techniques, suitable for receiving the screws (4) for tightening the flange (11) to the counter-flange (12).
