Title
(EN) SEALED CONNECTION BETWEEN A METTA0IC PIPE AND A FLEXIBLE PIPE AND METHOD FOR PRODUCING THE SAME
(FR) RACCORD ETANCHE ENTRE UN TUBE METALLIQUE ET UN TUYAU FLEXIBLE, ET PROCEDE DE FABRICATION D'UN TEL RACCORD
Abstract
(EN)
The invention relates to a connection (3) and a method of producing a sealed connection (1) between a rigid metallic pipe (2) and the fitting (3) of an elastomer flexible pipe (4) comprising a core (5) of corrugated steel with parallel threads (6), previously exposed at one end and with a backup cylindrical metallic mesh (7). The connection comprises a cylindrical fitting (11) made of steel and having the same outer diameter as the core on the end (12) of which it is welded (14), a sleeve-shaped insert (13) whose inner bore cooperates with said fitting (11) and comprising on one side an end portion (16) for attachment to or forming the rigid pipe (2), and on the other side, an end portion (13) ending in the shape of a bevel (19) and force fitted between the upper portion of the steel core (5) and the metallic mesh (7), and a crimping dowel (20).
(FR)
II s'agît d'un raccord (3) et d'un procédé de fabrication d'un raccord etanche (1) entre un tube rigide métallique, (2) et un embout (3) de tuyau (4) flexible en elastomère muni d'une âme (5) en acier ondule à filets parallèles (6) préalablement dénudée à son extrémité et d'une tresse métallique cylindrique (7) de renfort. Le raccord comporte un embout cylindrique (11) en acier de même diamètre externe que l'âme sur l'extrémité (12) de laquelle il est soude (14), un insert (13) en forme de manchon dont l'alésage interne coopère avec ledit embout (11) et comportant d'un coté une partie d'extrémité (16) de fixation sur, ou formant, le tube rigide (2) et de l'autre coté une partie d'extrémité (13) se terminant en biseau (19) insérée en force entre la partie supérieure de l'âme en acier (5) et la tresse métallique (7, et une bague (20) de sertissage.
