摘要:: 钛合金无缝管因具有优异的综合性能而在航空航天、船舶、石油化工等领域得到重要应用。目前，钛合金管材产量已占据钛产品产量的20%，在我国需求用量也越来越大，在钛及钛合金市场中占据重要的地位。然而，钛合金无缝管的制备对设备要求高、工艺复杂，不同类型钛合金无缝管的制备具有不同的工艺路线和工艺参数。重点对采用挤压和斜轧穿孔制备不同类型钛合金无缝管坯，以及对管坯进一步轧制、旋压、特种锻造加工制备成品管材的方法和研究进展进行了归纳和评述，以期为制备钛合金无缝管选择合适的方法提供参考。

Abstract:: 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．
