Abstract

L'invention concerne un tuyau ondulé à double ou triple paroi qui comprend une série de cavités définies entre les parois du tuyau et au moins certaines de ces cavités sont remplies de mousse. Une fois introduite, la mousse peut modifier les propriétés dans des régions sélectionnées du tuyau ondulé ou sur toute sa longueur. Le fait de remplir de mousse des cavités associées aux composants de raccordement de tuyau constitue un exemple selon lequel une résistance supplémentaire peut être ajoutée dans une zone qui, sinon, peut limiter l'évaluation globale du tuyau. Le fait de remplir de mousse des cavités présente également des propriétés d'absorption acoustique souhaitables qui permettent au tuyau d'être utilisé dans d'autres applications.
