Research of Operational Properties of Materials Applied in Iecp

The main spectrum of materials used in ESP designs is considered. The corrosion resistance of metallic materials, as well as the degree of degradation of the mechanical properties of rubber compounds after exposure in a corrosive environment, simulating operational effects, have been determined. Autoclave tests of structural metallic and nonmetallic materials were carried out in an aqueous-salt solution containing chloride, bicarbonate, calcium, sodium and potassium ions, as well as dissolved hydrogen sulfide and carbon dioxide at a temperature of 120 ° C. Also metal tests in the field of hydrochloric acid with a pH value equal to zero. Corrosion rates are calculated to take into account the duration of contact with the test medium. The effect of a corrosive environment on the change in the mechanical properties of rubber compounds has been investigated. This article opens a series of studies to establish relationships in the "composition-structure-properties" triad for ESP materials under various operating conditions.
