Abstract (en)
[origin: EP2695685A1] The apparatus is used for reforming a pipe member by improving the roundness of an axial region which is at least a part of the pipe member in a direction of an axis of the pipe member, the apparatus includes: an anvil ring disposed outside the pipe member so that a circularly-formed inner circumference face of the anvil ring is opposed to an outer circumference face of the axial region; an inner roller disposed inside the pipe member so that an outer circumference face of the inner roller is in contact with an inner circumference face of the axial region; a pressing unit which apples a pressure contact force between the inner circumference face of the anvil ring and the outer circumference face of the pipe member, thereby causing plastic deformation at the axial region by using the inner circumference face of the anvil ring as a reforming face; and a rotation unit which rotates the pipe member with respect to the inner roller around the axis of the pipe member.
