Prospects for the further development of the oil and gas industry are mainly associated with the development and commissioning of high-rate fields. In this regard, the production of more economical and durable equipment by machine-building enterprises, an increase in the level of its reliability and competitiveness, as well as further improvement of technological production processes, is of paramount importance. The evolution of technology in a broad sense is a representation of changes in designs, manufacturing technology, their direction and patterns. In this case, a certain state of any class of TC is considered as a result of long-term changes in its previous state; transition from existing and applied in practice vehicles to new models that differ from previous designs. These transitions, as a rule, are associated with the improvement of any performance criteria or quality indicators of the vehicle and are progressive in nature. The work is devoted to the study of the evolution of the quality of high-pressure valves during the period of their intensive development.

Keywords: technical system, evolution of technology, high-pressure valves, shut-off devices, gate.

 Аbstract

Alloying elements are specially introduced into titanium-based alloys in order to improve technological and operational characteristics. Necessary for this purpose, it is necessary to expand the understanding of the possibilities and establish the regularities of the mechanical behavior of ternary Ti-Mo-Sn alloys by varying the alloy composition and selecting the appropriate thermomechanical treatments, creating a fine structure in relation to binary titanium-molybdenum alloys. To clarify the principles of optimal alloying of the titanium alloys under study, let us analyze the change in mechanical properties, starting with some binary alloys. Elements such as Sn and Mo are more often used to alloy titanium in order to harden it, and quite often they are used together and in different proportions. Based on experimental data. To understand the role of each element in creating the properties of ternary Ti-Mo-Sn alloys, let us analyze some compositions with a fixed value of one of the elements.

Keywords: titanium-molybdenum alloys, alloying elements, thermomechanical treatment.
