(FR) TUYAU DE RACCORDEMENT POUR SYSTEME CHAUFFE-EAU ET/OU ADOUCISSEUR D'EAU, ET SON PROCEDE DE FABRICATION
Abstract
(EN)
The invention relates to a coupling pipe for water heating and/or conditioning systems, of the type having one or more braided layets (2, 3). The main feature of the invention is that the pipe comprises, in the inside of the braided coating thereof, a first and a second tubular layer (4, 5), the first tubular layer being made of a halogenated thermopolymeric material (EPDM), and the second layer being made of a halogen-butylelastomeric material. The present invention also relates to a method for making the pipe.
(FR)
L'invention concerne un tuyau de raccordement pour un système chauffe-eau et/ou adoucisseur d'eau, du type comprenant au moins une couche tressée (2, 3). La principale caractéristique de cette invention réside dans le fait que ce tuyau comporte, à l'intérieur de son revêtement tressé, une première et une seconde couches tubulaires (4, 5), la première couche tubulaire étant fabriquée dans un matériau thermopolymère halogéné (EPDM), la seconde couche étant constituée d'une matière élastomère halogène-butyle. La présente invention concerne également un procédé de fabrication de ce tuyau.
