Abstract (en)
[origin: WO2006129025A1] The invention concerns a method for machining the ends of a metal conduit (1) for forming, when it is abutted with identical conduits, a pipeline pipe, to form at the plane of the parting line (3) with another identical conduit a V-shaped bevel. The invention is characterized in that it consists in cutting the ends of the conduit so that the profile of each end has at least one first cross-section, at the inner edge, designed to constitute part of the root face of the V-shaped bevel and an arc-shaped section linking said cross-section of the profile to a rectilinear section (5) inclined relative to the cross-section of said profile, at the outer edge of the tubular part. The invention is applicable to metal conduits, in particular for pipelines.
