Abstract
A ceramic-backed elbow featuring an extended chamber which alters the flow of fluent through the elbow section. This chamber is lined with a ceramic material and ceramic tiles. The remainder of the elbow is similarly coated with a ceramic mixture. The elbow could be placed into a coating pan upon the tiles being adhered to the elbow, and the entire elbow may be coated with an abrasive-resistant coating. A thin metal skin may then be applied over the entire surface of the coating.
Claims16
A fluent material handling system including a wear-resistant elbow, the system comprising:
- the elbow including a first open end, a second open end, and a bend including an interior face, an exterior face, an inner arc, and an outer arc;
- a plurality of abrasion-resistant tiles adhered to the exterior face of said bend, said abrasion-resistant tiles configured to prevent material traveling through said elbow from forming a leak within said elbow;
- said plurality of abrasion-resistant tiles further comprising a plurality of uniform interlocking tiles, each comprising a flat top face, a flat bottom face, a convex front edge, and a concave rear edge;
- and
- wherein each concave rear edge is configured to receive a respective convex front edge of an adjacent one of said plurality of uniform interlocking tiles.
A fluent material handling system including a wear-resistant elbow, the system comprising:
- the elbow including a first open end, a second open end, and a bend including an interior face, an exterior face, an inner arc, and an outer arc;
- said bend including a continuous annular channel;
- a chamber formed on the outer arc of said bend opposite said first open end, said chamber opening into said channel on one side tangential to said channel wall with the other side of said chamber merging with said outer arc at a point outwardly offset parallel to the central axis of said inlet port by one quarter of the diameter of the channel;
- a plurality of abrasion-resistant tiles adhered to the exterior face of said bend in proximity with said chamber, said abrasion-resistant tiles configured to prevent material traveling through said elbow from forming a leak within said elbow;
- said bend including a continuous annular channel;
- a chamber formed on the outer arc of said bend opposite said first open end;
- a layer of coating material covering at least a portion of said elbow and said plurality of abrasion-resistant tiles, said coating material adhering said tiles to said elbow;
- and
- an abrasion-resistant metal skin applied to at least a portion of the elbow exterior over said coating material;
- said plurality of abrasion-resistant tiles further comprising a plurality of uniform interlocking tiles, each comprising a flat top face, a flat bottom face, a convex front edge, and a concave rear edge;
- and
- wherein each concave rear edge is configured to receive a respective convex front edge of an adjacent one of said plurality of uniform interlocking tiles.
The system of claim 11, further comprising a metal patch configured to patch a hole in said thin metal skin.
A method of constructing an abrasion-resistant elbow for a fluent pipe system, the method comprising the steps:
- adhering a plurality of ceramic tiles to an exterior face of an elbow comprising a first open end, a second open end, and a bend including an interior face, an exterior face, an inner arc, and an outer arc;
- connecting said elbow first open end to a first pipe section;
- connecting said elbow second end to a second pipe section;
- transferring fluent material through said pipe section, wherein said abrasion-resistant tiles configured to prevent material traveling through said elbow from forming a leak within said elbow;
- wherein said plurality of ceramic tiles further comprise a plurality of uniform interlocking tiles, each comprising a flat top face, a flat bottom face, a convex front edge, and a concave rear edge;
- and
- wherein each concave rear edge is configured to receive a respective convex front edge of an adjacent one of said plurality of uniform interlocking tiles.
