FIELD: metallurgy.
SUBSTANCE: rolling mill is used including a mandrel for rolling supported by at least one mandrel holder, also it includes at least two pressure shaping tools impacting the pipe from the outside, preferably they should be two external rolls. Also a measurement device is used for determination of pipe wall thickness during pressure shaping method. Device for support displacement is connected by operating connection to mandrel holder support and this device for support displacement is connected to measurement device.
EFFECT: higher production quality.
