The performance evaluation and the control methods of high strength TA18 alloy tubes were investigated. The pole-figures, inverse pole-figures and orientation distribution function were measured and calculated by X-ray diffraction technique and used to characterize the textures in tubes. The textures and properties of domestic and abroad tubes were evaluated. It is found that the {0001}<100> texture is commonly dominant in high performance tubes. The test methods of contractile strain ratio (CSR) were presented. The relationship between CSR and other properties was discussed. The performance control method by controlling ratio of wall reduction to diameter decrease (Q) was put forward for Ti alloy tubes. Results show that increasing of the Q can increase the radial texture in Ti alloy tubes and enhance the value of CSR, resulting in improving the performance of the tubes.
