Abstract

The invention concerns metallurgy. A method includes gradual decrease of the radii of curvature of cross sections of edges and central section of skelp in the direction of its advance in open and closed forming passes, in the welding pass and pipe in calibration passes from its flat state upstream of the first forming pass to the radius of finished pipe after last calibration pass. In the closed passes and in welding pass simultaneously, with decrease of the radii of curvature of the cross sections of central section, an increase of the radii of curvature of the cross sections of areas of edges is created, while in the calibration passes, simultaneously with decrease of the radii of curvature of the cross sections of areas of edges, an increase of the radii of curvature of the cross sections of central area is created.
