ABSTRACT:
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.
