FIELD: technological processes; transportation.
SUBSTANCE: case with central axis channel features connection and work parts, and work rollers mounted at an angle to case axis. Work part includes series of two sections, conical support and conical thrust ones. Conical thrust section has larger cone angle than conical support section. Cylindrical grooves serving as supports for work rollers are made at conical support section. Work rollers include cylindrical shaping section and conical thrust gauging section and are located in conical roller holder with axial movement drive.
EFFECT: possibility of pipe section distribution; facilitated input of device into pipe and removal from pipe after distribution, enhanced durability of device.
