Title
(EN) A CLAMPING STRAP, A PIPE END JOINT AND AN EXHAUST SYSTEM
(FR) SANGLE DE SERRAGE, JOINTURE D'EXTREMITES DE TUYAUX ET SYSTEME D'ECHAPPEMENT
Abstract
(EN)
A clamping strap for joining two pipe ends, said clamping strap presenting a shape corresponding to the circumference of the two pipe ends. The clamping strap (8) includes a first web member (1) extending parallel to the pipe walls (12, 13), a second web member (2) extending from each side of the first web member (1) and inwards towards the pipe walls, a compressible sealing band (4) arranged of the inner side of the first web member (1) between the two second web members (2) and of a width substantially corresponding to the width of the first web member (1), when seen in use in a cross-sectional direction though the central axis of the pipes (10, 11). A third web member extending parallel to the pipe walls (12, 13) extends from the innermost end of each second web member (2). The invention relates also to a pipe end joint as well as an exhaust system where tubular modules are joined by means of such a clamping strap.
(FR)
Cette invention se rapporte à une sangle de serrage servant à joindre deux extrémités de tuyaux, cette sangle ayant une forme correspondant à la circonférence des deux extrémités de tuyaux. Cette sangle de serrage (8) comprend une première bande (1) s'étendant parallèlement aux parois (12, 13) des tuyaux, une seconde bande (2) partant de chacun des côtés de la première bande (1) et s'étendant vers l'intérieur en direction des parois des tuyaux, un collier d'étanchéité compressible (4) situé du côté interne de la première bande (1) entre les deux secondes bandes (2) et d'une largeur correspondant sensiblement à la largeur de la première bande (1), lorsqu'il est vu, en cours d'utilisation, dans le sens de la section transversale à travers l'axe central des tuyaux (10, 11). Une troisième bande s'étendant parallèlement aux parois (12, 13) des tuyaux part de l'extrémité interne de chacune des secondes bandes (2). Cette invention se rapporte également à une jointure d'extrémités de tuyaux, ainsi qu'à un système d'échappement dans lequel des modules tubulaires sont joints au moyen d'une telle sangle de serrage.
