Abstract
Official abstract text for this publication.
A conduit which may be a hose defines an inner bore and has an elastomeric liner with hard material segments embedded in and backed by the liner and exposed to the inner bore. The hard material segments absorb high energy impacts while the elastomeric liner backs the segments and absorb sufficient energy to mitigate the more brittle nature of the wear-resistant segments.
First claim
Opening claim text (preview).
What is claimed is: 1 . A conduit defining an inner bore and having an elastomeric liner comprising at least one hard material segment embedded in and backed by the elastomeric liner, and exposed to the inner bore. 2 . The conduit of claim 1 comprising a plurality of hard material segments exposed to the inner bore. 3 . The conduit of claim 1 which is a pipe. 4 . The conduit of claim 1 which is a hose. 5 . The conduit of claim 1 wherein the elastomeric liner comprises a rubber or a polyurethane. 6 . The conduit of claim 1 wherein the hard material segment comprises tungsten carbide, or sintered tungsten carbide, a cermet, or a ceramic material. 7 . The conduit of claim 6 wherein the 3-D shape of hard material segment comprises tiles, blocks, cylinders, spheres, or ovoids. 8 . The conduit of claim 6 wherein the 2-D shape of hard material segment which faces the conduit bore comprises squares, rectangles, circles, ovals, hexagons or other polygons, or combinations thereof. 9 . The conduit of claim 7 wherein the tiles are parallel to or angled away from a plane which is parallel to a central axis of a conduit which is straight, or a plane tangential to the central axis of a conduit which is curved. 10 . The conduit of claim 9 wherein the tiles are angled away at about 0° to about 90°. 11 . The conduit of claim 1 wherein the thickness of hard material segments is in the range of about 5 to about 50 mm and the elastomer backing is in the range of about 5 mm to about 100 mm.
