Examine the primary causes of defects in the firmware and sleeves rolled pipe mills longitudinal rolling. Research has established the need for improved calibration roll piercing mill to reduce the level of breakdown in front of the toe of the mandrel. To meet the challenges of designing and calculating the calibration settings piercing mill and rolling mill is designed longitudinal mathematical tools, methodology and software for computer modeling of the deformation. Using computer modeling developed and implemented new calibration roll piercing mill and rolling mill of the longitudinal, thus significantly reducing the level of internal defects.
