FIELD: process engineering.
SUBSTANCE: invention relates to production of pipes and can be used for handling of large-diameter pipes. Pipe is fed axially via inductive heater that surrounds said pipe in circle. Intake poppet sleeve is arranged nearby pipe end to displace axially in direction of pipe feed and rigidly engaged with pipe bender. Note here that said poppet sleeve locks the pipe from inside to create axial force for pushing the pipe through inductive heater unless its rear end is locked at front clamping lock at bending arm.
EFFECT: better pipe positioning and reliability of its extraction.
