An apparatus for deforming a pipe includes a boxed structure having an entry and exit for the pipe. The boxed structure acts as a constraint on a peripheral of the pipe along a path of movement thereof. An elongate wedge member depends inwardly from the boxed structure and is arranged in use to lie alongside the path of movement of the pipe and to project increasingly into the pipe as the pipe moves past the wedge member in a forward direction in the path of movement. The pipe to be deformed in the path of movement is engaged progressively increasingly by the wedge member whereby to indent progressively a part of the peripheral wall of the pipe such to deform the pipe longitudinally in the path of movement with the pipe through the boxed structure.
