Abstract: The invention includes systems and methods for heating a fluid and transporting the fluid at an elevated temperature. The system includes a fiber reinforced spoolable pipe. This spoolable pipe may include an inner layer, at least one reinforcing layer, at least one heating element, and at least one insulation layer. The heating element may be located external to the inner layer. The invention also includes methods of deploying and rehabilitating a spoolable pipe for transporting a fluid at elevated temperature.

Abstract: A spoolable pipe is disclosed, the spoolable pipe having an internal pressure barrier formed about a longitudinal axis, and a reinforcing layer(s) enclosing the internal pressure barrier. In one embodiment, the reinforcing layer(s) can include fibers having at least a partial helical orientation about approximately thirty and about approximately seventy degrees relative to the longitudinal axis, and, the wall can include at least one external layer enclosing the reinforcing layer(s) and having a permeability at least ten times greater than the permeability of the internal pressure barrier. The reinforcing layer(s) can further include a coating. The pipe can also include an energy conductor(s) integrated with and/or located between the internal pressure barrier and/or the reinforcing layer(s).

Abstract: A composite article is provided that includes a polyolefin layer, a tie-layer, and a non-polyolefin. The tie-layer may comprise a silicon modified polyolefin. Methods are also provided for adhering a polyolefin to a non-polyolefin. Such articles may used, for example, in composite tubing.

Abstract: The present disclosure is directed to methods and systems for pipeline rehabilitation. The methods and systems disclosed herein permit the rehabilitation of long lengths of previously installed pipe and minimize the need for creating multiple access points to the pipeline. The disclosed systems and methods are particularly suited for rehabilitating buried and undersea pipelines or pipelines installed in areas of restricted access.
