FIELD: construction, pipeline.
SUBSTANCE: invention pertains to pipeline transport and is employed for pipelines capping. The first and the second spaced rings each having sealing face in the plane perpendicular to the axis of the pipeline are welded on to the external surface of the pipeline. Protective cover is welded to the rings totally covering the part of the pipe in between the rings. A machine for making holes is movably connected to the open upper part of the protective cover; short section of the pipeline between the rings is cut off and taken out, leaving two open unprotected ends of the pipe. The first and the second sealing elements are placed between the rings, provided that each has front sealing face. Sealing elements are moved from each other at a distance for insertion into the sealing coupling with sealing faces of the rings closing open unprotected ends of the pipe.
EFFECT: expanded variety of technical aids.
