%X The paper deals with the production of could drawn precision seamless steel tubes with three-drawn and two-drawn single-run technology. The aim of experiment is to verify the possibility of drawing rolled tubes of size   70 ¡Á 6.3 mm (material E355) with three-draw single-run technology without intermediate recrystallising annealing on the final size   44 ¡Á 3 mm in the fixed reduction and two-draw single-run technology   70 ¡Á 6.3 mm without intermediate recrystallising annealing on the final size   50 ¡Á 3.75 mm in the fixed reduction and with size   70 ¡Á 6.3 mm without intermediate recrystallising annealing on the final size  45 ¡Á 3.75 mm in the fixed reduction. Advise the impact choice of the reduction on roughness of inner surface of tubes.
