A tube and fitting assembly is made by the method of relatively moving a tube into an internal bore in a fitting with the internal bore extending end-to-end in the fitting, longitudinally compressing the tube to radially expand it into engagement with the wall of the internal bore, internally threading either the tube or the fitting and with the threads being adapted to receive a second member until it is sealed fluid-tight against the tube and there is therefore no need for a fluid-tight seal between the tube and the first fitting. The invention is also the tube and fitting as constructed by such method. The foregoing Abstract is merely a resume of general applications, it is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
L'invention concerne un ensemble tube et raccord réalisé selon le procédé qui consiste à donner un mouvement relatif à un tube (12) pour l'engager dans un évidement (29) d'un raccord (11), cet évidement (29) allant d'un bout à l'autre du raccord (11). Ensuite, on comprime longitudinalement le tube (12) pour en obtenir l'expansion radiale lorsqu'il vient en prise avec la paroi de l'évidement (29), et on procède au filetage interne du tube (12) ou du raccord (11), ce filetage étant conçu pour recevoir une seconde pièce (13) qui, en position finale, est adaptée contre le tube (12) dans des conditions d'étanchéité: il n'est donc plus nécessaire d'introduire un joint étanche entre le tube (12) et le raccord (11) cité en premier. On décrit par ailleurs les modes de réalisation de l'ensemble tube (12) et raccord (11) obtenus à l'aide de ce procédé.
