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).
