где tз а г, tт р - толщина стенки соответственно трубчатой заготовки и трубы, Δtоп - величина обжатия стенки изнутри трубчатой заготовки по гребню ручья валков.The invention relates to the processing of metals by pressure, in particular to pipe production and can be used in the manufacture of pipes by the method of cold or hot rolling. The technical challenge is the alignment of deformations and stresses along the perimeter of the tubular billet during longitudinal rolling of pipes. This technical problem is achieved by the fact that in the method of longitudinal rolling of pipes, including the deformation of a tubular billet by means of strand rollers on a fixed mandrel with a cylindrical gage part and a compression section adjacent to it with a large section, for example, conical, deformation is carried out in a round caliber with no outliers at a ratio
where t z and g , t t p - wall thickness, respectively, tubular billet and pipe, Δt op - the amount of compression of the wall from the inside of the tubular billet along the crest of the roll stream.
