Abstract: A polymeric composition for insulating fluid and/or gas transport conduits, such as off-shore oil and gas pipelines operating at temperatures of about 200° C. or higher in water depths above 1,000 metres. The outer surface of the conduit is provided with at least one layer of solid or foam insulation comprising a high temperature resistant polysulfone having sulfone, ether and isopropylidene bridging groups, and/or a polyphenylsulfone or a polyethersulfone.

Abstract: A method of providing a foamed insulation coating on at least a portion of a pipe, including extruding a melt stream over the pipe portion. The melt stream includes a matrix polymer and expandable fillers in an unexpanded state, the melt stream being maintained at a sufficiently high temperature to maintain the matrix polymer in extrudable form and at a sufficiently high pressure to maintain the expandable fillers in the unexpanded state. Once extruded, the expandable fillers are permitted to expand into an expanded state at a lower pressure.

Abstract: A pipeline monitoring system, utilizing RFID sensors. The pipeline monitoring system includes a pipeline having at least one RFID sensor for a wireless remote detection of any one or more of pipeline conditions including hydrocarbons presence, moisture presence, temperature and strain, and an RF interrogator or transceiver capable of interrogating said sensor.
