  • Insulating inserts for field joints of coated rigid pipelines
    Patent number: 10731787
    Abstract: An insulating insert is positioned around a field joint of a pipeline to insulate the field joint. The insert includes a longitudinal series of annular or part-annular filler segments of insulating material, curved about a longitudinal axis, that are each joined to one or more adjacent segments of the series by at least one link. The links may be webs, rods or articulated links. The links are flexible relative to the segments to facilitate bending of the insert along its length by enabling relative angular displacement between adjacent segments of the series.
