Webb6 juli 2024 · The critical velocity is of course the velocity at which solid particles settle in the pipe so it’s important to keep the slurry velocity above this minimum value. However, pumping the slurry at too high a velocity increases the pressure losses which can result in wear of the piping system. WebbNguyen et al. tested the slurry erosion of stainless steel SUS-304 by using new advanced erosion test rig, where the multiphase flows of alumina sand and water were utilized as the erodents. Initially the erosion rate was high but reduced (gradually) subsequently. In addition, the erosion rate increased with impact velocity.
