FIELD: plastic processing.
SUBSTANCE: group of inventions relates to the field of pipeline construction. Apparatus for applying protective sheeting (9) of polymer material around a cutback on a pipeline has a frame located close to a pipeline, extending along a longitudinal axis. Manipulator is fitted to the frame and comprises a guide system movable between a rest position at a distance from the pipeline, and a work position in which the guide system is fitted around the pipeline. Apparatus comprises an extrusion die movable selectively along the guide system and around the pipeline to supply and apply protective sheeting around the cutback on the pipeline.
EFFECT: group of inventions can be used for anticorrosive protection of uncoated pipe ends after annular welds.
