Title
(EN) PIPE TUBULAR ELEMENT COMPRISING A RIGID LONGITUDINAL PORTION AND A FLEXIBLE LONGITUDINAL PART IN ONE SINGLE PIECE
(FR) ELEMENT TUBULAIRE DE CONDUITE COMPORTANT UNE PARTIE LONGITUDINALE RIGIDE ET UNE PARTIE LONGITUDINALE SOUPLE EN UNE SEULE PIECE
Abstract
(EN)
The invention concerns a pipe element having one longitudinal axis (2) along which extend a tubular rigid part (3) and a tubular flexible part (4) in one single piece, the rigid part (3) comprising an end portion with a substantially radial surface (8) for connection (8) to an end portion (11) of the flexible part (4) and, at the connecting radial surface (8), means defining an additional surface (10) for connecting the end portion (11) of the flexible part (4) with at least part of the additional connecting surface (10) extending substantially parallel to the longitudinal axis (2).
(FR)
Elément de conduite, possédant un axe longitudinal (2) le long duquel s'étendent une partie rigide (3) et une partie souple (4) tubulaires et en une seule pièce, la partie rigide (3) comportant une extrémité présentant une surface sensiblement radiale (8) de liaison à une portion extrême (11) de la partie souple (4) et, au niveau de la surface radiale de liaison (8), des moyens (9) pour définir une surface supplémentaire (10) de liaison à la portion extrême (11) de la partie souple (4), au moins une partie de la surface supplémentaire de liaison (10) s'étendant de manière sensiblement parallèle à l'axe longitudinal (2).
