Method and apparatus for reinforcing a pipeline

摘要

Systems and methods for reinforcing an existing pipeline. In some embodiments, the methods include positioning a pipeline wrapping apparatus on the existing pipeline, wherein the pipeline wrapping apparatus comprises a winding head, feeding a strip of material through the winding head, attaching an end of the strip of material to the existing pipeline, and helically wrapping the strip around the existing pipeline by rotating the winding head and axially translating the winding head relative to the existing pipeline.

主权项

1. A pipeline wrapping apparatus comprising:
a winding head configured to receive a strip from a spool of reinforcing material and rotate around an existing pipeline; and a movement assembly comprising:
a frame;a pair of tracks operable to axially translate the pipeline wrapping apparatus relative to the existing pipeline;cylinders on opposing ends of the tracks and configured to press the tracks against the existing pipeline; andpivoting anchors connecting the tracks, frame, and cylinders such that:
the tracks are tilted relative to an axis of the pipeline, andoperation of the movement assembly exerts counter torque on the pipeline.
