    摘要： A polymeric composition for insulating fluid and/or gas transport conduits, such as off-shore oil and gas pipelines operating at temperatures of 130°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 thermoplastic having low thermal conductivity, high thermal softening point, high compressive strength and high compressive creep resistance. The high temperature resistant thermoplastic is selected from one or more members of the group comprising: polycarbonate; polyphenylene oxide; polyphenylene oxide blended with polypropylene, polystyrene or polyamide; polycarbonate blended with polybutylene terephthalate, polyethylene terephthalate, acrylonitrile butadiene styrene, acrylonitrile styrene acrylate, or polyetherimide; polyamides, including polyamide 12 and 612 and elastomers thereof; polymethylpentene and blends thereof; cyclic olefin copolymers and blends thereof; and, partially crosslinked thermoplastic elastomers, also known as thermoplastic vulcanizates or dynamically vulcanized elastomers.

    摘要： A method for forming a field joints between sections of coated or insulated pipe which are to be welded together and incorporated into an undersea pipeline for carrying single or multi-phase fluids such as oil, gas and water. The method includes the application of a liquid epoxy layer which overlaps a lip of the factory-applied FBE coating protruding beyond a chamfered end of the factory-applied insulation layer, and which may be applied over the entire weld joint area. The liquid epoxy layer is partially cured by application of heat, and a layer of powdered adhesive is applied onto the partially cured liquid epoxy layer. The adhesive is subsequently sintered and activated by application of heat to its outer surface. The outer surfaces of the adhesive layer and the chamfers are then preheated and the thermal joint insulation is injection molded over the entire joint area. Throughout the entire method the temperature of the factory-applied FBE coating is maintained below its glass transition temperature so as to avoid weakening the bond between the FBE coating and the underlying steel pipe. The number and sequence of steps can be varied, depending at least partly on whether the liquid epoxy and adhesive layers are applied in a pipe coating facility or in the field.

    摘要： A wrappable, styrenic thermal insulation product for application to flexible, armoured pipe is in the form of an elongate tape of generally rectangular cross- section, optionally being provided with interlocking and/or overlapping portions so as to provide a continuous insulating layer when one or more layers of the tape are wound around the pipe. The interlocking and/or overlapping portions may be of various configurations. The tape is comprised of polystyrene or a styrene-based thermoplastic having high compressive creep resistance, high compressive strength and low thermal conductivity and may be foamed or unfoamed. A flexible, armoured pipe incorporates one or more layers of the wrappable, styrenic thermal insulation product between an outer armour layer and an outer polymeric sheath.

    摘要： A heat-shrinkable article suitable for use as an insulating or coating material comprises a crosslinked composition of a polypropylene homopolymer or copolymer and an ethylene-propylene elastomer. The article is formed by a process comprising: i) creating a blend of the polypropylene homopolymer or copolymer and the ethylene-propylene elastomer by melt mixing; ii) melt processing the blend produced in I) to produce a melt processed material; iii) crosslinking the melt processed material produced in ii)by exposing it to radiation to produce a crosslinked material; iv) stretching the crosslinked material at a first temperature close to or above its softening or melting point and subsequently cooling it to a second temperature below its softening or melting point, to thereby freeze the crosslinked material in its stretched form. Subsequent heating of the article close to or above its softening point or crystalline melting point results in recovery of the pre-stretched dimensions of the article. Due to its relatively high content of polypropylene, the heat-shrinkable article thus produced has greater toughness and rigidity than polythylene-based systems, making it suitable for use as insulation for wives and cables a heat-shrinkable corrosion resistant sleeves for high-temperature transmission pipeline joints, and for heat-shrinkable tubing or shapes for electrical insulation and mechanical protection.
