Abstract： Titanium alloys are widely used in aerospace， chemical engineering， medical equipment and other fields due to their unique and excellent properties. However， the machinability of titanium alloy materials is poor， especially in the production of titanium alloy pipes， which often face processing difficulties and high costs due to their high strength， high hardness， and poor thermal stability. In recent years， with the development of technology， the processing technology of titanium alloy pipes has been continuously innovated and optimized. Therefore， it is necessary to explore the processing technology and performance optimization of titanium alloy pipes， with a focus on analyzing key process links including as cast billet preparation， radial forging， and double annealing， as well as their effects on the mechanical properties， microstructure， and surface quality of titanium alloy pipes. Research has shown that through innovative process improvement and reasonable process parameter control， the performance of titanium alloy pipes can be significantly improved， production costs can be reduced， and the overall utilization rate of materials can be enhanced.
