“…Currently, titanium alloys are widely used for such systems [1,2]; they are used in high-pressure pipelines, where aluminum alloys become inoperable, and steels cannot compete due to the lower specific strength characteristics, or pipelines operating with corrosive media [3]. Titanium alloys have better specific strength characteristics in comparison with aluminum alloys and steels, high corrosion resistance and fatigue resistance, and can be used at elevated temperatures, at which the use of aluminum alloys is impossible or impractical [4,5].…”
