A flexible joint (2) comprises a first rigid wall portion (4), a second rigid wall portion (14), a flexible wall portion (12) extending between the first and second rigid wall portions (4, 14), the three wall portions defining a longitudinal passage through the joint and being arranged along the length of the passage, a sleeve (22) secured at one end to the first rigid wall portion (4) and extending through the passage so as to overlap the second rigid wall portion (14), the sleeve (22) being spaced from the flexible wall portion (12) and free to move relative to the second rigid wall portion (14). In one aspect, a layer of insulating material (24) is provided on a surface of the sleeve (22) whilst leaving the space between the sleeve (22) and the flexible wall portion (12) substantially free to be occupied by process fluid when in use. In a second aspect, the length of the portion of the sleeve (22) overlapping the second rigid wall portion (14) is at least five times the distance of the sleeve (22) from the second rigid wall portion (14), as measured perpendicular to the sleeve (22).
Ce joint articulé flexible (2) comprend une première portion rigide (4) de paroi, une seconde portion rigide (14) de paroi, une portion flexible (12) de paroi s'étendant entre les première et seconde portions rigides (4, 14), ces trois portions délimitant un passage longitudinal à travers le joint et étant disposées sur la longueur du passage, ainsi qu'un manchon (22) fixé au niveau d'une de ses extrémités à la première portion rigide (4), s'étendant à travers le passage de manière à chevaucher la seconde portion rigide (14), espacé de la portion flexible (12) et mobile par rapport à la seconde portion rigide (14). Dans un aspect de l'invention, on a déposé une couche de matériau isolant (24) sur une surface du manchon (22), alors que l'on a laissé sensiblement libre, pour être occupé par un fluide de traitement lors de l'utilisation du joint, l'espace situé entre le manchon (22) et la portion flexible (12). Dans un second aspect de l'invention, la longueur de la portion du manchon (22) chevauchant la seconde portion rigide (14) représente au moins cinq fois la distance séparant le manchon (22) de cette portion (14), distance mesurée perpendiculairement à celui-ci (22).
