  • Patent number: 10161556
    Abstract: An insulated high-temperature transport conduit for use in undersea environments. The conduit comprises a continuous steel pipe having at least a first layer of thermal insulation provided over its outer surface. The first layer of thermal insulation comprises a polymer composition having a thermal conductivity of less than about 0.40 W/mK and long-term heat resistance at continuous operating temperatures within the range from about 150° C. to above about 205° C. The first thermal insulation layer comprises a polymer composition comprising a polymer selected from the group consisting of one or more fluoropolymers, hydrogenated nitrile butadiene rubber (HNBR), and a blend of one or more fluoropolymers with HNBR. The conduit may further comprise second and third layers of insulation on top of the first layer, along with a corrosion protection coating underlying the first thermal insulation layer.

  • Patent number: 9810366
    Abstract: A method for forming a high temperature field joint between two insulated pipe sections, and an insulated conduit having a low temperature field joint. The conduit comprises a steel pipe with a corrosion protection coating and a pipe insulation layer comprising a polymer composition having thermal conductivity of less than about 0.40 W/mk, and/or heat resistance to continuous operating temperatures from about 150° C. to above about 205° C. After a circumferential weld joint is formed between the two pipes, a first field joint insulation layer is applied over the joint area, the first field joint insulation layer comprises a polymer composition having heat resistance to continuous operating temperatures from about 150° C. to above about 205° C.
