Research of resistance to water-jet wear of plastic and steel pipes. Assessment of the main parameters that affect the wear rate of hydraulic transport systems
It has been found that the use of certain types of thermoplastic elastomers as a co-extruded coating of the inner surface of plastic pipe systems can significantly increase the lifetime of pipeline hydrotransport when exposed to hydraulic mixtures, in particular tailings of iron ore processing. The comparison of polyethylene and steel pipes resistance to water-jet wear is made. The influence of the concentration, dispersion, and speed of hydraulic mixtures on the wear rate is estimated.
