Abstract

L'invention concerne un tuyau de raccordement télescopique formé par abouchement d'un manchon (1) et d'un tuyau d'insertion (2). Un tuyau fileté (11) est disposé au niveau d'une extrémité libre du manchon (1). Une pluralité de rainures annulaires (13) sont disposées sur un côté extérieur du manchon (1). Une pluralité de rainures annulaires (24) sont disposées sur un côté extérieur d'une extrémité de gainage du tuyau d'insertion (2) et des bagues d'étanchéité (25) sont gainées dans les rainures annulaires (24). Un tuyau fileté (28) est disposé au niveau d'une extrémité libre du tuyau d'insertion (2). Le tuyau de raccordement télescopique utilise une structure de gainage, règle la longueur d'un abouchement de manière télescopique, peut s'adapter à une opération d'abouchement pour des raccords filetés de tuyau ayant des distances de raccordement différentes et est commode et pratique.
