Abstract

Способ изготовления тонкостенных труб, включающий волочение трубы в конусной волоке на закрепленной цилиндрической оправке, отличающийся тем, что волочение трубы осуществляют с величиной коэффициента вытяжки по сечению трубы λ в интервале 1,25≤λ≤1,48, при этом коэффициент вытяжки по стенке λs составляет 0,90λ≤λs≤0,94λ.A method of manufacturing thin-walled pipes, including drawing the pipe in a conical fiber on a fixed cylindrical mandrel, characterized in that the drawing of the pipe is carried out with the coefficient of drawing along the pipe cross section λ in the range of 1.25≤λ≤1,48, with the coefficient of drawing along the wall λs is 0.90λ≤λs≤0.94λ.
