Abstract (en)
[origin: WO7800004A1] A method of securely joining a pipe (1) to a pipe fitting (3) without the need for rotating either element. The fitting (3) or in some cases the pipe (1), is expanded by heating whereby the other element may be inserted in it and the elements are secured together upon cooling by the interengagement of matching grooves (4) and ribs (14) which are provided on the circumferential surfaces of the elements.
Abstract (fr)
Un procede d'accouplement permettant d'assujettir solidement un tube (1) a une piece de raccordement (3) sans rotation d'aucun element. La piece de raccordement (3) ou, dans certains cas, le tube (1), est dilatee par chauffage, ce qui permet d'y introduire l'autre element et, lors du refroidissement, les nervures (14) qui s'engagent dans les rainures circonferencielles (4) en regard usinees sur la surface des elements assujettissent l'un a l'autre ces derniers.
