Abstract: An elbow in a pneumatic transport system is lined on the outside to combat wear from abrasive substances conveyed by the system. The lining comprises a plurality of liner segments extended only across the backside of the elbow''s exterior surface and set end to end along the elbow in the directon of flow through it. The liner segments are attached to the elbow by an adhesive and by steel bands. The opposing end faces of adjacent liner segments are generally parallel and a layer of adhesive exists between them. The liner segments are preformed from a durable material such as aluminum oxide.
