Annotation:
Premature release of pipeline elements due to hydro- or gas-abrasive wear is one of the main problems faced in the oil and gas industry. This article is devoted to the study of the resistance of steel pipeline materials under waterjet action. The materials used on existing pipelines are considered, as well as promising methods of surface hardening of metal using the example of cementation and metallization coatings. The main dependences and the degree of influence of such parameters as the velocity and angle of impact of the flow of a medium containing solid insoluble particles on the degree of waterjet destruction of the materials under study are determined, and their comparative stability under simulated impacts is assessed. The study of the influence of individual operational parameters (speed, flow angle, amount of abrasive) on the resistance of materials under waterjet action is a fairly promising and urgent task aimed at optimizing and improving the efficiency of the equipment used during operation and, not least, increasing the operational life of the pipeline, in particular its individual elements exposed to critical impact.
