DETECTION OF CIRCUMFERENTIAL EROSION OF A CONDUIT

摘要

An erosion detector and a method of determining erosive wear within a condui t are disclosed. The conduit (10) has an outer metallic wall (11) lined with a wear resistant lining (12) of a moulded composite. A conductor (17) is embedded within the lining during formation thereof. The conductor extends substantially about the circumference of the conduit and is spaced from the interior surface by a selected distance. Means are provided to monitor electrical continuity of the conductor. Once the lining wears and the conductor is broken, a continuity test will indicate that the lining has wor n to the depth to which the conductor was embedded within the lining.
