<p>A flexible tube for conveying a mixture of a liquid and a solid material containing objects with sharp points, edges or similar projections, the internal wall part of said tube consisting of an elastic material (1), especially rubber, in which a wearproof material is present in the shape of rod-shaped elements (2) which are provided essentially parallel and at a distance from one another in said internal wall part (1) in such a way that they extend themselves between the inner and the outer surface of said internal wall part (1), the shortest distance between the most closely spaced wall parts of said elements (2) being at least equal to the greatest dimension (D) of the rod-shaped elements. (2) as seen in the radial direction of said elements (2).</p> |
