Flexible tube for conveying abrasive materials and related manufacturing method

A flexible tube for conveying abrasive materials comprising

• a tubular body extending along a main extension axis, the tubular body having a thickness extending from an inner side wall, which delimits an inner cavity used for transporting an abrasive material, to an outer side wall, opposite said inner side wall along a radial direction, perpendicular and incident with said main extension axis,
• wherein said tubular body comprises a covering layer at the outer side wall, and
• wherein said tubular body comprises an elastomeric matrix, inside which are at least partially embedded circular disks having a diameter (D) and flat faces, in ceramic material, namely a first flat face directly facing said inner cavity, so as to at least partially constitute the inner side wall and a second flat face embedded in the elastomeric matrix, wherein, with respect to a diametric projection plane, passing through the main extension axis, the circular disks are arranged on rows parallel to a first laying direction with a first constant pitch (p1), and on rows parallel to a second laying direction, with a second constant pitch (p2), said first and second laying directions being perpendicular to each other.
