Abstract

Un raccord de tuyaux, particulièrement pour tuyaux en plastique, comprend une partie intérieure (11) en forme de manchon que l'on introduit dans l'extrémité du tuyau (10) que l'on veut raccorder afin de soutenir la paroi (12) du tuyau à l'intérieur du tuyau et une partie extérieure (13) en forme de manchon qui entoure l'extrémité du tuyau du côté extérieur du tuyau en comprimant la paroi (2) du tuyau contre la partie intérieure (11), de sorte que l'extrémité du tuyau est serrée entre la partie intérieure (11) et la partie extérieure (13) du raccord. La surface extérieure de la partie intérieure (11) et la surface intérieure de la partie extérieure (13) sont pourvues d'une pluralité de stries annulaires (21, 22) qui font le tour des parties (12, 13) et ont une section transversale sensiblement triangulaire. Les stries (21) de la partie intérieure (11) sont axialement décalées par rapport aux stries (22) de la partie extérieure (13). Les stries (21, 22) ne s'enfoncent que partiellement dans la paroi (12) du tuyau,d e sorte qu'un espace (m) se forme entre la paroi (12) du tuyau d'une part et les parties intérieure (11) et extérieure (13) d'autre part, entre les stries (21, 22). De cette façon, l'expansion thermique du matériau du tuyau peut se produire radialement, en éliminant ainsi les risques de fuites dus à la déformation du matériau.
