A tell-tale wear monitor for pipes having wear resistant inner linings. A plurality of wear monitors is provided spaced apart along the length of a pipe section or spool and angularly spaced apart about the pipe circumference. Each of the wear monitors includes a plug member attached to the outer pipe casing and covering a tell-tale hole which extends through the pipe casing. The plug members are made of a material which, relative to the inner lining material, is readily worn away by abrasive contact with the material conveyed within the pipe. When the plug member is worn through, fluid flow is permitted through the tell-tale hole. The wear monitor provides a means for determining when maintenance of the pipe section should be scheduled and allows for extended useful life of the pipe section.
