It comprises inner three or more helical grooves with equal pitch of sections composed by two subsections. Said subsections are composed of three or more isosceles trapezoids and triangles, interconnected by sides. Said sections are interconnected by larger bases of trapeziums. Said subsections are connected so that the bases of isosceles triangles of one section are connected to top base of isosceles trapeziums in second subsection.
