The useful life of an abrasive material transport hose ( ) can be maximized if the hose is repositioned at the first signs of internal wear. This is accomplished by disposing at least two wear sensing elements ( ), each at a specified distance from the inwardmost surface of the inner tube ( ), and each monitoring a condition indicative of wear of the hose ( ) at its specified distance from the inwardmost surface of the inner tube. When the innermost wear sensing element ( ) implies wear, the hose can be repositioned to extend the useful life until the outermost wear sensing element ( ) indicates wear requiring replacement of the hose.
