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.

1. A method of reinforcing an existing pipeline, the method comprising:
positioning a pipeline wrapping apparatus on the existing pipeline, wherein the pipeline wrapping apparatus comprises a winding head and a track assembly; pressing opposing tracks of the track assembly against the existing pipeline; feeding a strip of reinforcing material through the winding head; attaching an end of the strip to the existing pipeline; operating the track assembly, thereby moving the pipeline wrapping apparatus along the existing pipeline; and rotating the winding head relative to the existing pipeline while moving the pipeline wrapping apparatus therealong, thereby helically wrapping the strip around the existing pipeline, wherein:
the tracks are tilted relative to an axis of the pipeline, andoperation of the track assembly exerts counter torque on the pipeline.
