description: This work is devoted the researching of factors affecting the fatigue failure of drill pipes of strength class S and G. The research set the following aims: 1. Analysis of the operating conditions affecting the fatigue of the drill pipe. 2. Investigation of the effect of surface roughness on the fatigue life of the drill pipe. 3. Study of the effect of the corrosive environment on the drill pipes fatigue life. The work was carried out in a testing laboratory on the basis of the Assembly and Technological complex "New Technologies and Materials", where a significant part of the actual material was collected: results of metallographic analysis of defective metal samples. Analysis has been conducted to demonstrate clearly how the number of non-metallic inclusions affects the fatigue life of drill pipes. The analysis was carried out on a Reichert-Jung MeF3A light microscope using Tixomet PRO according to GOST 1778-70 (w). As a result, the effect of operating time, non-metallic inclusions and corrosive environment on the fatigue failure of drill pipes was analyzed.
