Abstract
A pipe comprises an outer surface and an inner surface, where the inner surface includes an abrasion resistant material layer covering a substantial portion thereof. An adhesive layer affixes the abrasion resistant material layer to the inner surface. The abrasion resistant layer can reduce and prevent erosion-corrosion of the inner surface of a pipe transporting slurry.
