The article provides a systematization and comparative analysis of structure, phase composition, physical and mechanical properties of coldrolled pipes of titanium alloys PT-1M, PT-7M, Ti-3Al-2.5V. The analysis was carried out on deformable tubular semi-finished products at various stages of obtaining cold-rolled pipes. The influence of the degree of cold deformation on the strain hardening of samples from hot-extruded pipes of the alloys was established. Based on these data, recommendations were developed on the maximum allowable degrees of deformation during cold rolling of pipes made of PT-1M, PT-7M, Ti-3Al-2.5V alloys. The strain heating of alloys during cold rolling has been evaluated. It is shown that cold rolling of the studied alloys contributes to the strain hardening of pipes. When simulating cold rolling of pipes, the calculation of the Q-factor was carried out, which has a value of about 1. Cold rolling with such a value of the Q-factor leads to the formation of a texture of an inclined tangential prism alloying alloy from PT-1M to Ti-3Al-2.5V. It is noted that the intermediate and final annealing at 680 °C (PT-1M alloy), 750 °C (PT-7M allo.
