Abstract

Способ изготовления спиральношовных труб, при котором исходную полосу подают в формовочную машину с внутренним и наружным приводными валками, установленными под углом один к другому, формируют ее в трубную заготовку и сваривают, отличающийся тем, что, с целью повышения качества труб путем устранения пробуксовки трубной заготовки по наружному диаметру, трубную заготовку формуют при вращении внутреннего валка со скоростью большей скорости вращения наружного валка.A method of manufacturing spiral-seam pipes, in which the initial strip is fed into a molding machine with internal and external drive rollers mounted at an angle to one another, is formed into a pipe billet and welded, characterized in that, in order to improve the quality of pipes by eliminating the slip of the pipe billet on the outer diameter, the billet is formed by rotating the inner roll at a speed greater than the speed of rotation of the outer roll.
