The main methods of improving the feeding mode taking into account the D/S ratio of rolled pipes are considered. It is proposed to carry out rolling of pipes in the with variable feed rate according to a given program, as well as new solutions for butt shell rolling. Two new directions for the preparation of the front ends of the sleeve liners on a four-row hydraulic press and on a planetary type reeling machine are considered. New methods of preparing the rear ends of the sleeves by thinning the wall at the rear end of the sleeve in the process of piercing the workpiece on the rotary piercer mill by moving the mandrel, as well as by crimping the rear end of the sleeve on the mandrel on a two-punch hydraulic press. The combined use of the considered methods of improving the inoculation mode is proposed, which will increase productivity and reduce metal consumption in the cut.
