Systems and methods for making pipe, and method of installing the pipe in a pipeline

摘要

A method for restoring a degraded pipeline, the method comprising: removing a degraded part of an inner flow pipe of a pipeline leaving a space between two spaced-apart sections of the inner flow pipe; positioning a new pipe in the space; connecting the new pipe to the two spaced-apart sections of the inner flow pipe thereby re-establishing a flow channel through the inner flow pipe; the new pipe having a core pipe with a first strengthening wrap thereon, a second strengthening wrap around the first strengthening wrap, and a protective outer wrap on the second strengthening wrap.

1. A method for restoring a degraded pipeline,
the method comprising: removing a degraded part of an inner flow pipe of a pipeline leaving a space between two spaced-apart sections of the inner flow pipe; making a new pipe using a wrapping system for wrapping a core pipe, the wrapping system on a frame, the frame movable adjacent the core pipe without connection to the core pipe, the wrapping system located on the frame so that the wrapping system is entirely above the core pipe with the core pipe entirely outside of the wrapping system and beneath the wrapping system, the wrapping system comprising a stand-alone system unconnected to the core pipe, the frame having a plurality of rollers for facilitating movement of the frame with respect to the core pipe, the wrapping system including a roll of wrapping material on the frame above the core pipe; the frame including rollers powered by at least one motor, the at least one motor on the frame, the frame having an on-board power generator for providing power to the at least one motor to power the rollers to move the frame, moving the frame along the core pipe by powering the rollers with the at least one motor, the at least one motor powered by the power generator, the core pipe extending through the frame as the frame moves; rotating the core pipe beneath the wrapping system as the frame moves with the wrapping system above the core pipe so that rotation of the core pipe pulls material off the roll of wrapping material onto the core pipe; dispensing wrapping material from the roll of wrapping material on the frame down onto the core pipe at a desired wrap angle producing the new pipe; positioning the new pipe in the space; and connecting the new pipe to the two spaced-apart sections of the inner flow pipe thereby re-establishing a flow channel through the inner flow pipe.
