Abstract: According to data from oil and gas companies, abrasive wear caused by various types of mechanical impurities accounts for 20 to 40 percent of failures of critical equipment, including tubing, submersible equipment, and production pipelines. This article presents experimental studies of the dependence of hydroabrasive wear on low-carbon steels by a water jet containing SiO2 particles on their mechanical properties and carbon equivalent. It is shown that increasing yield strength, strength, and hardness of the steel, a nonlinear decrease in hydroabrasive mass wear is observed according to a hyperbolic law, consistent with the adopted mathematical model. The regression equations, obtained based on the selected mathematical model, were statistically significant, indicating the validity of this model. The study established a hyperbolic relationship between hydroabrasive mass wear and the carbon equivalent of steel. The resulting regression equations, reflecting this relationship between wear and carbon equivalent, were statistically significant. By introducing the carbon equivalent of steel, a multivariate mathematical model was supplemented to reflect the relationship between hydroabrasive mass wear and the densities of the medium components, the total number of interactions leading to micro cutting, the radius of the abrasive particles, their attackangle, the frictioncoefficient between them and the target surface, the mixturedynamic pressure, the density of the working fluid and particle mixture, and the yield strength of the material. It was found that the lowest hydroabrasive mass wear was observed in the steel sample from the pilot smelting with high content of carbon and chromium, as well as a certain amount of molybdenum and vanadium.
