An internal inclined sub-channel, or ramp device, for suspending and/or re-suspending solids within a pipeline system during transport of slurry may be provided to various components of the slurry transport system to control or reduce localized and severe wear that often occurs in slurry pumps. Embodiments of the ramp device may be adequately configured to alter slurry multiphase flow patterns and/or disrupt traditional moving/sliding bed regime phenomena. Embodiments of the ramp device may be adequately configured to raise coarse abrasive particulates from bottom portions of a slurry pipe section—where a higher concentration and/or a larger presence of coarser particles may be present. Embodiments of the ramp device may be installed in proximity of and/or upstream of slurry pumps to prevent occurrences of severe localized wear at the inner diameter of the pump suction side wall around the bottom or 6 o'clock position.
