A pipe elbow having a composite ceramic wear liner which is particularly adapted to resist abrasive wear from particulate material conveyed through the pipe elbow. The composite ceramic wear liner is comprised of four series of polyhedron shaped ceramic wear blocks disposed at angularly spaced locations around the circumference of the elbow flow passageway. A mixture of wear resistant particles and binder surrounds the wear bricks and provides an abrasion resistant wear surface along those portions of the pipe elbow which are less subject to abrasive wear. The pipe elbow is provided with a removable cover plate in order to access and replace the series of wear bricks located along the outside center line of the pipe elbow most subject to wear.

An apparatus, comprising: a pipe elbow defining a tubular shaped flow passageway for allowing the transmission of abrasive materials therethrough, said pipe elbow including an outer casing having an inner surface, said pipe elbow further including a sacrificial liner and an inner wear liner lining the entire inner surface of said outer casing, said sacrificial liner spaced inwardly from said outer casing and defining said flow passageway, said inner wear liner having a substantially greater wear resistance to abrasive material flowing therethrough than said outer casing, said inner wear liner including a castable mixture of wear resistant particles and binder cast in the space between said outer casing and said sacrificial liner, said inner wear liner further including no more than four series of abrasion resistant polyhedron shaped wear bricks encased within said castable mixture and arranged along the length of said pipe elbow, said wear bricks having a planar shaped surface which faces in a direction generally towards the center line of said pipe elbow, said mixture of wear resistant particles and binder extending entirely around said flow passageway.
