    摘要: A system for carrying out operations along an annular junction portion of a pipeline is provided with: a frame comprising a C-shaped structure, which is configured to be selectively clamped about a pipeline extending along a longitudinal axis and near an annular junction portion, and at least one driving device arranged along an arc of an annular path and coupled to the structure; a support arm configured to rest on the pipeline and connected to the structure for maintaining the laying plane of the driving device substantially orthogonal to the longitudinal axis; a carriage slideably coupled to the driving device; and at least one operating device configured to carry out operations along the annular junction portion and cantilever supported by said annular segment.
