Abstract

Procedimento per il fissaggio di un inserto tubolare di rinforzo (12) ad una struttura tubolare metallica (10), comprendente le fasi di:- ricavare un foro (30) nella parete della struttura tubolare (10) mediante deformazione verso l'interno di una porzione della parete, in modo che la porzione di parete deformata formi un collare (32),- inserire con forzamento una porzione di estremità dell'inserto tubolare (12) all'interno del suddetto collare (32), e - introdurre liquido ad alta pressione all'interno della struttura tubolare (10) in modo da provocare una compressione del collare (32) contro la porzione di estremità (26) dell'inserto tubolare (12).(Figura 1)Procedure for fixing a reinforcing tubular insert (12) to a metal tubular structure (10), comprising the steps of: - making a hole (30) in the wall of the tubular structure (10) by deforming towards the inside of a portion of the wall, so that the deformed wall portion forms a collar (32), - forcibly inserting an end portion of the tubular insert (12) inside the aforementioned collar (32), and - introducing liquid at high pressure inside the tubular structure (10) so as to cause a compression of the collar (32) against the end portion (26) of the tubular insert (12). (Figure 1)
