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.
