ABSTRACT:
An early warning system for a material transfer system having an elongated area to be monitored for internal wear caused by erosive flow action of a transfer material. A material transfer conduit has an inner surface forming a flow passageway for the transfer material and an outer wall surface with a wear detection indicator normally visible in situ at an elongate section of the outer wall and being subject to obliteration upon wear-through of an underlying portion. A translucent or transparent outer containment layer surrounds the outer wall surface of the transfer conduit The wear indicator is colored to contrast with the transfer material and indicates wear by an eroded area which can be visually observed through the outer translucent layer.
