Abstract

L'invention concerne un tuyau de refoulement avec un élément extérieur et un élément intérieur pour le transport, c'est-à-dire pour la conduction de milieux quelconques, notamment à action abrasive. L'invention a pour objet de fournir un tuyau de refoulement avec un élément extérieur et un élément intérieur pour le transport, c'est-à-dire pour la conduction de milieux quelconques, notamment à action abrasive, qui ne présente pas de joints longitudinaux défavorables pour la résistance à l'usure, de sorte que le tuyau de refoulement ait une plus longue durée de vie utile s'il est utilisé de manière correcte. Cet objet est réalisé par le fait que le tuyau de refoulement se compose d'une couche intérieure et d'une couche de revêtement appliquée sur cette couche intérieure, les deux couches étant connectées fixement l'une à l'autre et la couche intérieure se composant de bagues de protection anti-usure individuelles (1) ainsi que d'une couche de caoutchouc mince (2). Les bagues de protection anti-usure (1) se composent de matériau en céramique et sont vulcanisées avec la couche de caoutchouc (2), et la couche de revêtement se compose de supports de solidité (3).
