Titanium alloy seamless pipes have been widely used in aerospace，shipping，petrochemistry and other fields due to their excellent comprehensive performance．At present，the output of titanium alloy pipes accounts for 20% of the total output of titanium products，and the demand in China is also increasing，occupying an important position in the titanium and titanium alloy markets．However，the preparation of titanium alloy seamless pipes has high equipment requirements and complex processes．The preparation of different types of titanium alloy seamless pipes has different process routes and parameters．Focus in this review is placed on summarizing and reviewing the preparation methods and research progress of seamless pipe blanks of different titanium alloy by extrusion and rotary piercing，and further preparing finished pipes by rolling，spinning and special forging，which can provide some reference for selecting appropriate methods when preparing titanium alloy seamless pipes．
