摘要： 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.
