Предлагаемое устройство служит дл обработки трубы с одного конца, но можно устанавливать зеркально второе такое же устройство и одновременно обрабатывать оба конца, что повышает производительность стана в два раза. При этом необрабатываемый центральный участок не испытывает значительных усилий и не деформируетс .The proposed device serves to process the pipe from one end, but it is possible to install a mirror-like second device and simultaneously handle both ends, which increases the productivity of the mill twice. At the same time, the unprocessed central area is not experiencing significant efforts and is not deformed.
