Abrégé

The invention relates to a device for the internal bending of pipes (100), in particular of coated pipes, for pipelines with a base body (11) which can be positioned in the pipe and which has on at least one side (12), preferably the underside, at least one support surface (13) with an inner wall (101) of a pipe (100) to be bent, wherein the base body (11) has a support surface (13) opposite, preferably the upper side, on which at least one tool for introducing a bending force into the pipe (100) is movably provided, wherein the tool is movable relative to the base body (11) via at least one actuator (18, 20) for introducing the bending force. The invention provides that the tool is provided as a tool element (21) which has at least two bending force introduction sections (28, 29) for introducing the bending force into the pipe (100), which are each movable relative to the base body (11) by at least one actuator (18, 20).

Abrégé

The invention relates to a device for the internal bending of pipes (100), more particularly coated pipes, for pipelines, the device comprising a main body (11), which can be positioned in the pipe and which has, on at least one side (12), preferably the bottom side, at least one contact surface (13) for contacting an inner wall (101) of a pipe (100) to be bent, wherein the main body (11) has a side opposite from the contact surface (13), preferably the top side, on which at least one tool for applying a bending force to the pipe (100) is movably provided, which tool can be moved relative to the main body (11) by means of at least one actuator (18, 20) in order to apply the bending force. According to the invention, the tool is provided as a tool element (21) which has at least two bending-force application portions (28, 29) for applying the bending force to the pipe (100), which bending-force application portions can be moved relative to the main body (11) by means of at least one actuator (18, 20) each.
