FIELD: welded pipes production. SUBSTANCE: values of pulling forces of stands of rollers are determined. The calculations are made for closed rollers stand with maximum pulling force. Difference of values of pulling forces between chosen and rest driven stands and widths of zones of lag behind and overtaking of rollers contact surface with pipe blank are calculated according to given dependance. During adjustment process equality of pulling forces of driven stands is achieved by changing values of angular speeds in accordance with definite dependance. EFFECT: method is used in welded pipes production. 9 dwg, 6 tbl
