Abstract

La présente invention concerne un tuyau doté d'un élément chauffant pour empêcher le tuyau de geler et d'éclater en hiver. Ledit tuyau comprend : un tuyau de forme cylindrique définissant un espace creux à travers lequel s'écoule un fluide ; un élément chauffant encastré dans un côté intérieur de la surface incurvée du tuyau de façon à entourer ladite surface incurvée, ledit élément chauffant générant de la chaleur quand il est alimenté en courant. L'invention permet d'empêcher le tuyau de geler et d'éclater, même s'il n'est pas entouré d'un isolant thermique distinct en hiver. Ceci élimine le procédé incommode consistant à entourer le tuyau d'un isolant thermique. De plus, quand il est disposé à l'intérieur d'un mur sans accès par l'extérieur, le tuyau peut être empêché de geler et d'éclater, ce qui améliore la fiabilité du produit.
