The results of erosion-corrosion testing in pilot plant slurry pipelines are related to the behaviour of operating slurry pipelines and the control of erosion-corrosion in such systems by use of inhibitors, solution conditioning and adjustment of slurry parameters.

The erosion-corrosion component of the total wear is oxygen-mass-transfer controlled and the magnitude of the erosion-corrosion can be estimated using well established mass transfer correlations.

There is a breakaway velocity for each slurry below which mechanical erosion of the pipe is not a problem and it is suggested that slurry pipelines may be operated below this velocity but under conditions of particle size and velocity where the pipe wall is kept free from rust and scale to prevent pitting corrosion. The erosion-corrosion would be controlled by inhibitors and/or dearation resulting in a smooth rust and scale free pipe.
