By the methods of macro- and microstructural, diffraction analyses, mechanical tensile tests the structure and proper- ties of the extrusion pipe from Ti-3Al-2.5V alloy intended for the subsequent cold rolling were studied. The extrusion pipe was produced according to the scheme: expansion on vertical press molding on horizontal press. It is shown that at expansion of pierced shell, the structure and phase structure did not undergo essential changes in comparison with an initial hot-rolled semi-finished product in two-phase (α+β)-area. Extrusion in the recommended temperature range provided formation of rather homogeneous, well worked macro- microstructures from tangential basic texture of α-phase and producing in extrusion pipes from Ti-3Al-2.5V alloy of complex of mechanical characteristics necessary for carrying out the subsequent cold rolling which is used at the final stages of producing pipes on TREX technology.
