Texture formation processes at all technological stages of tube manufacture were considered. It has been established that at the stage of hot deformation and manufacture of TREX tubes, tangential and radial textures are formed, a large share of tangential component of the texture. Influence of main factors of the technological process on formation of texture and properties was established. Conditions for formation of a maximum amount of radial texture in tubes which ensure improvement of service properties of tubes were determined. To create maximum amount of radial texture in tubes, total reduction rate in passes and the wall to diameter reduction ratio (factor Q) are important. The reduction rate should be increased, especially in the last passes, to 75…85%. Heat treatment (stress relief annealing) practically does not change the tube texture.
