Abrasion resistant ceramic elbow (Abrasion resistant ceramic elbow)

A pipe elbow for transmission of abrasive materials therethrough defining a square or rectangular cross-sectional shaped flow passageway in the area wherein the direction of flow of said abrasive material is changed, said pipe elbow including an outer casing comprised of planar or curved planar surfaces having an outer and an inner surface, said pipe elbow further including a plurality of tiles lining the entire inner surface of said outer casing so that the inner surfaces of the tiles define a flow path defined by at least four sides of a box shaped bend section comprising a deflection wall receiving the greatest abrasive force, two side walls parallel to each other and perpendicular to the deflection surface, and a fourth wall perpendicular to the side walls and facing the deflection wall, said inner tiles having a substantially greater wear resistance to abrasive material flowing therethrough than said outer casing. When the elbow having a square or rectangular cross-sectional shaped flow passageway is mated to a pipe having a circular mating surface, fluid turbulance in the transition area between the square or rectangular cross section area of the elbow and the round cross section area is held to a minimum by the provision of corner transition tiles.
