Patent
CA 2260122
The present invention indicates excessive wear on the outer cover of a hose in order to help avoid unexpected ruptures and spills. The invention is a hose with an outer cover. The outer cover has two layers made of rubber or plastic. The outer cover has an inner layer of one color (e.g. yellow) and an outer layer of another color (e.g. black). When the outer cover wears down to expose color of the inner layer, the end user is made aware that outer cover wear is approaching the reinforcement layer and that the hose should be replaced.
L'invention se rapporte à un procédé de détection d'usure excessive de la gaine protectrice extérieure d'un tuyau, permettant d'éviter des ruptures ou des écoulements soudains. L'invention concerne également un tuyau et sa gaine protectrice extérieure. Ladite gaine protectrice extérieure a deux couches constituées de caoutchouc ou de plastique. La couche intérieure est d'une certaine couleur (jaune, par exemple) et la couche extérieure est d'une autre couleur (noir, par exemple). Lorsque la gaine protectrice extérieure est usée jusqu'à laisser apparaître la couleur de la couche intérieure, l'utilisateur en déduit que la couche de renforcement va être atteinte et que le tuyau doit être remplacé.
