Abstract

Procedimento per la piegatura di un tubo a sezione trasversale oblunga per scambiatori di calore. Il procedimento comprende le fasi di provocare una rotazione relativa di ampiezza sostanzialmente pari a 180° fra due rami (2a, 2b) del tubo (2) attorno ad un asse (8) parallelo all'asse maggiore (4) della sezione trasversale del tubo in modo da ottenere due rami rettilinei (2a, 2b) collegati fra loro da una porzione di raccordo arcuata (2c) e provocare una rotazione relativa di ampiezza sostanzialmente pari a 90° fra ciascuno dei suddetti rami rettilinei (2a, 2b) e la porzione di raccordo (2c).(fig. 4).Procedure for bending an oblong cross-section tube for heat exchangers. The method comprises the steps of causing a relative rotation of a width substantially equal to 180 ° between two branches (2a, 2b) of the tube (2) around an axis (8) parallel to the major axis (4) of the cross section of the tube so as to obtain two rectilinear branches (2a, 2b) connected to each other by an arcuate connection portion (2c) and to cause a relative rotation of a width substantially equal to 90 ° between each of the aforementioned rectilinear branches (2a, 2b) and the portion connector (2c). (fig. 4).
