These parameters examine the particle-particle and particle-pipe wall interaction pattern. Various laboratory experimental tests were done to determine the effect of particles on pipe walls and a range of values for the particle mass loading and stokes number were determined. These values became the interpretation criteria for analyzing results and suggesting recommendations. However, from this research result, the particle mass loading of 0.82, stokes number of 1.20 and mass transfer coefficient of 6.06 W m-2 °C were obtained. These values show that there was strong evidence of particle-wall interaction, which could have caused wear. When the pipe under study was cut into sections and visual examination was carried out, it was observed that cutting wear actually occurred in the internal geometry of the pipe. The severity of the wear is attributed to the small diameter of the pipeline under study; the size, coupled with the agglomerated stones is believed to have allowed for close particle wall interaction. From the findings, pipes whose depth of cut is high enough to significantly affect their load bearing capacity should be changed and sizable particles should be removed from the flow system to avoid wear.
