Description

Трубы на угол |3 (например, на 2-5°). В результате такого перемещени  стенка конца трубы деформируетс  по геликоидальной кривой, что.приводит к закручиванию волокон металла и увеличению его прочностных характеристик.Pipe angle | 3 (for example, 2-5 °). As a result of this movement, the wall of the pipe end is deformed along a helicoidal curve, which causes the metal fibers to curl and increase its strength characteristics.
