Wear resistant elbow

A wear resistant pipe elbow for use in transporting fluent materials such as in a pneumatic conveying system. The elbow includes a wear back or wear resistant surface on the inside of the outer wall of an arcuate channel connecting an inlet leg with an exit leg of the elbow. The wear resistant surface may include a plurality of steps which extend symmetrically toward the inlet leg and the outlet leg. The center of the steps is preferably located on a radius extending from the center of curvature of the arcuate channel through the junction of the longitudinal axis of the inlet leg and the longitudinal axis of the outlet leg. The wear back or wear resistant surface may be made up of a member including a plurality of ribs which defined spaced apart pockets. These pockets are designed to receive and at least partially retain material being conveyed through the system. While the ribs or steps in the wear resistant backing will wear, the depth of metal in this area will prolong the life of the elbow.
