Method for producing high-strength titanium alloy seamless tube

The invention relates to and aims at providing a method for producing a high-strength titanium alloy seamless tube and belongs to the field of metallurgy. The method for producing the high-strength titanium alloy seamless tube sequentially comprises the following steps: heating a round billet, perforating, sizing, carrying out hydraulic drawing and temperature correcting, and the like, thereby obtaining the titanium alloy seamless tube finally. The method for producing the high-strength titanium alloy seamless tube has the advantages that deformation at the medium temperature of 750-850 DEG C is increased to directly obtain the titanium alloy tube meeting performance requirements, a heat treatment process is eliminated, and the aims of simplifying working procedures, optimizing a technology, reducing cost, shortening a production cycle, improving production efficiency and improving product quality are achieved. The titanium alloy tube produced by the method has the advantages of thin gas permeable layer, high outer diameter and wall thickness dimensional accuracy, few inner and outer surface defects, high yield and the like. The method provides a new choice for production of the titanium alloy tube and has broad application prospects.
