Sand erosion can remove protective corrosion scales on pipe walls and cause severe erosion corrosion damage. Many factors influence erosion-corrosion. The goal of this work is to obtain an understanding of how these factors work together to cause severe erosion-corrosion damage. To reach this goal, a combination of erosion testing and flow modeling, including sand erosion, is used. This approach includes the effects of pipe geometry, size, and pipe wall material; flow velocity, fluid density and viscosity; sand size, shape, density, and sand production rate on the loss of wall thickness due to sand erosion and erosion-corrosion. Progress has been made to the extent that a procedure for prediction erosion penetration rate is presented. The procedure is a generalization of several earlier empirical methods for specific sand erosion conditions reported in the literature. Results from the erosion prediction model are compared to experimental data presented in the literature.
