A method of joining a pair of tubular ends (1, 2) comprises: providing the tubular ends with intermeshing tapered edges (3,4); joining the tubular ends by inserting an adhesive between the tapered edges and pressing the tapered edges (3,4) together; arranging an axial load carrier collar (5) around the joined tubular ends; inserting an adhesive between the inner surface of the collar (5) and the outer surfaces of the joined tubular ends (3, 4); and inducing the adhesive to bond the inner surface of the collar (5) to the outer surfaces of the joined tubular ends. The axial load carrier collar (5) may be equipped with a series of flexible reinforcement strips (8, 9), which carry a majority of axial loads exerted on the tubular joint, such that only a minimal axial load is exerted on the bonded tapered edges (3, 4).
L'invention concerne un procédé d'assemblage d'une paire d'extrémités tubulaires (1, 2) comprenant les étapes consistant à : munir les extrémités tubulaires de bords biseautés entrecroisés (3,4) ; assembler les extrémités tubulaires en insérant un adhésif entre les bords biseautés et en pressant les bords biseautés ensemble (3,4) ; agencer un collier de support de charge axiale (5) autour des extrémités tubulaires assemblées ; insérer un adhésif entre la surface interne du collier (5) et les surfaces externes des extrémités tubulaires assemblées (3, 4) ; et inciter l'adhésif à coller la surface interne du collier (5) aux surfaces externes des extrémités tubulaires assemblées. Le collier de support de charge axiale (5) peut être équipé d'une série de bandes de renforcement flexibles (8, 9), qui portent une grande partie des charges axiales exercées sur le joint tubulaire, de sorte que seule une charge axiale minimale soit exercée sur les bords biseautés collés (3, 4).
