Title
(DE) KUNSTSTOFF-METALL-VERBUNDROHR FÜR SANITÄR- UND/ODER HEIZUNGSANLAGEN
(EN) COMPOSITE PLASTIC-METAL PIPE FOR PLUMBING AND/OR HEATING SYSTEMS
(FR) TUYAU COMPOSITE CONSTITUE DE PLASTIQUE ET DE METAL, CONÇU POUR DES INSTALLATIONS SANITAIRES ET/OU DES INSTALLATIONS DE CHAUFFAGE
Abstract
(DE)
Das Kunststoff-Metall-Verbundrohr für Sanitär- und/oder Heizungsanlagen, ist mit einem Innenrohr aus einem polymeren Kunststoffmaterial mit einer Dichte im Bereich zwischen 0,937 bis 0,948 g/cm3 und einem Schmelzindex, einer Haftvermittlerschicht auf dem Innenrohr und einer Metallschicht auf der Haftvermittlerschicht versehen. Die Haftvermittlerschicht besteht aus einem polymeren Kunsrstoffmaterial, das im Wesentlichen die gleiche Dicke, im Wesentlichen die gleichen mechanischen Eigenschaften wie z.B. Dehnung, Festigkeit und Schlagzähigkeit und/oder im Wesentlichen den gleichen Schmelzindex wie das Kunststoffmaterial des Innenrohres aufweist.
(EN)
Disclosed is a composite plastic-metal pipe for plumbing and/or heating systems, comprising an inner pipe that is made of a polymeric plastic material having a density ranging from 0.937 to 0.948 g/cm3 and a certain melt-flow index, an adhesive layer on the inner pipe, and a metal layer on the adhesive layer. The adhesive layer is made of a polymeric plastic material which is provided with substantially the same thickness, essentially the same mechanical properties, e.g. expansion, strength, and impact resistance, and substantially the same melt-flow index as the plastic material of the inner pipe.
(FR)
L'invention concerne un tuyau composite constitué de plastique et de métal, conçu pour des installations sanitaires et/ou des installations de chauffage, comprenant un tuyau interne constitué d'un matériau plastique polymère dont la densité est comprise entre 0,937 et 0,948 g/cm3 et présentant un indice de fusion donné, une couche adhésive qui est appliquée sur ce tuyau interne, et une couche métallique qui recouvre ladite couche adhésive. Cette couche adhésive est constituée d'un matériau plastique polymère présentant sensiblement la même densité, sensiblement les mêmes propriétés mécaniques, telles que dilatation, solidité et résilience, et/ou sensiblement le même indice de fusion que le matériau plastique dont est constitué le tuyau interne.
