FIELD: technological processes.
SUBSTANCE: method includes installing the pipe onto workholder, forming crimps under action of axial force applied to pipe, and of force moment, which is formed under interaction of workholder and rollers, located around longitudinal axis of roller pipe. At that, each roller is misaligned in parallel to reference axis of the pipe for a value, which does not exceed outer radius of the pipe. This is done to create resulting force vector, which defines force moment relative to pipe axis and rotates the pipe along its longitudinal axis.
EFFECT: technological features increase, so does the quality of the product manufactured.
