Повышение механических свойств и долговечности насосных штанг

Abstract

This paper is devoted to analyzes of the microstructure and properties of recovered trial sucker rods after working life, in order to determine the suitability of the proposed treatment regimes. Statistical data processing was used in the analysis of the mechanical properties. It is determined that during the process of recovery rolling of sucker rods with accelerated cooling yield strength of rods compared with yield strength produced by Ocher Machine Building Plant increased up to 1.4 times, elongation – up to 2 times, impact elasticity – ut to alnost 3 times.
