Abstract: A frame assembly for inspection of pipeline girth weld, having a support frame releasably coupled to a mounting band that comprises of two clamshell halves. The clamshell halves are coupled via quick release coupling mechanisms. By removing one of the clamshells, or uncouple the two clamshells at one coupling point, the frame assembly permits a RTR scanner assembly to be laterally displaced along the length of the pipeline.

Abstract: In an injection molded polypropylene field joint of an oil or gas pipeline, the three- dimensional geometry of the injection molded/cast coating can have an influence on the stress placed on the line coating during cooling. Specifically, it has been found that molding or casting a coating having circumferential grooves, or other groove geometry, proximal to the interface with the line coating, will reduce line coating failure proximal to the field joint, in particular line coating failure related to the initial spooling/reeling of the pipe.

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.

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.

Abstract: A method of coating a field joint and a coated field joint formed thereby. The field joint coating includes a first thermal insulation material injection molded over the uncoated field joint to form a first layer, and a second thermal insulation material injection molded over the first layer to form a second layer. The second material has a greater flexibility than the first material and a lower maximum operating temperature than the first material. In certain embodiments, the second material forms a significant part of the volume of the field joint coating.
