Erosion-Corrosion in Slurry Pipelines Available to Purchase

Electrochemical techniques have been used to determine the corrosion component of the erosion-corrosion of steel pipe carrying sand, iron ore, potash, limestone, and coal slurries, at commercial concentrations and velocities. The tests have shown that the presence of the solids can bring about a sharp increase in the corrosion rate, and that the effect is dependent on the solids concentration and slurry velocity. An explanation for this effect is given in terms of the erosive disruption of surface films which normally hinder the diffusion of oxygen to the corroding surface.
