  • Publication number: 20220299154
    Abstract: In an embodiment is provided a composition having a thermal conductivity of less than 0.2 W/m-K, the composition including a rubber and a thermoplastic olefin. In another embodiment is provided an insulated high-temperature transport conduit that includes a continuous steel pipe comprising one or more pipe sections, wherein the steel pipe has an outer surface and an inner surface; and a first thermal insulation layer disposed over the outer surface of the steel pipe, wherein the first thermal insulation layer comprises a composition having a thermal conductivity of less than 0.2 W/m-K, the composition comprising a rubber and a thermoplastic olefin.

  • Patent number: 6505650
    Abstract: A method for inhibiting external corrosion on an insulated pipeline including a pipe insulation positioned outside and around the pipe and a coating material around the insulation by positioning a plurality of concentrated charges of alkaline material in the insulation material.
    Type: Grant

  • Patent number: 6450736
    Abstract: A pipeline supported by a plurality of spaced, movable supports. The supports are not anchored but are movable with respect to the surface of the earth (e.g. tundra) thereby allowing the pipeline to move in response to temperature/pressure changes in said pipe. The supports are sized so that the pipeline will be elevated above the surface of the tundra at a height sufficient to allow water to flow under the pipeline as well as allowing small animals to pass thereunder. The movable supports may be either rolling supports which lie directly on the surface or sliding supports which are positioned on slidable stands or combination of both.

  • Patent number: 5633038
    Abstract: Carbon steel surfaces, particularly inside wall surfaces of steel pipelines, are treated with an organosilane coupling agent to improve the adhesion of epoxy, vinyl ester and similar polymer-type protective coatings to the surface. The organosilane coupling agent is applied to a cleaned steel surface in an aqueous and/or alcohol solution, the surface is dried to allow the organosilane to cure and the protective coating is then applied to the surface. Steel pipelines are coated in situ by cleaning the interior of the pipeline with hydrochloric acid, fresh water and a passivation agent such as phosphoric acid followed by pumping a slug of the organosilane coupling agent, in solution, through the pipeline between spaced apart pigs. The coupling agent is dried and a polymer coating is then applied by pumping a slug of the coating through the pipeline, also between two spaced apart pigs.
