Studies on the influencing parameters of erosion wear in slurry pipeline

The erosion wear in the commercial pipeline causes erosion wear in the slurry pipeline. The parameters mainly
expensive repairs, loss of production time, harmful include particle concentration, size, shape, surface charge,
environmental effects, less operative life and performance, slurry velocity, viscosity, temperature, impact angle, pipe
and serious financial losses in industries. An attempt is material, hardness, etc. Under this OLP, the slurries of red
given under OLP 120 to address the erosion wear in the mud, coal ash, iron ore and river sand have been taken as
slurry pipeline to improve the life-cycle of commercial test samples, whereas different grades of mild steel are
slurry pipelines in industries. chosen as pipe material. The idea is to generate erosion
The primary objective of the OLP is to investigate the wear data in the lab-scale erosion pot tester and further
slurry, flow, and design parameters that influence the validate with a field-scale pilot pipe-loop erosion set-up.
