Abstract (en)
[origin: CA2883031A1] The invention relates to a device for bending pipes (100), in particular coated pipes, preferably insulated pipes and/or pipes which are coated with PU foam/PU hard foam, for pipes having a base body (11) which can be positioned in the pipe and on which a running gear (12) is provided for displacement inside the pipe, and at least three contact elements (13, 14, 15) for establishing a contact to an inner wall (102) of the pipe for introducing a bending force, wherein at least two contact elements are provided on one side (16) of the base body on the ends of the base body, and at least one contact element is arranged on the opposite side (17) of the base body, and wherein at least one of the contact elements opposite of the base body is provided movably via a force introduction element (23) in the direction (A) of the inner wall of the pipe. The invention further relates to a method for bending such pipes.
