Title (EN) PIPE CONNECTION
(FR) RACCORD DE TUYAUX
Abstract:
(EN) A pipe connection comprises a connecting piece (2), a pipe (1 ) and a clamping ring (6). The pipe (1) and the clamping ring (6) are made of a material having memory properties. An end of the pipe (1) and the clamping ring (6) have been reversibly expanded co-jointly and firmly and sealingly shrunk to the connecting piece (2) by back shrinkage. Preferably the clamping ring (6) is made from a cross-linked polyolefin by injection molding.
(FR) La présente invention concerne un raccord de tuyaux comprenant une pièce de raccord (2), un tuyau (1) et une bague de serrage (6). Le tuyau (1) et la bague de serrage (6) sont obtenus à partir d’un matériau à mémoire. Une extrémité du tuyau (1) et la bague de serrage (6) ont été élargies de manière réversible et ce, à la fois conjointement et fermement, et réduites hermétiquement par retrait à la pièce de raccord (2). Idéalement, la bague de serrage (6) est fabriquée à partir d’une polyoléfine réticulée en effectuant un moulage par injection.
