摘要： A system for filling a gap between jacket ends at a joint between two lengths of jacketed pipe is disclosed, comprising: a mold and two pairs of side straps encircling the mold. The mold comprises a sheet of material having first and second ends and opposing side edges, the sheet including a pair of slots cut into the side edges at a predetermined distance from the second end and defining a flap. One pair of straps encircles the mold but passes under the flap through the slots. The second pair of straps encircles the mold and passes over the flap. The mold is positioned around a pipe joint so as to define an annular gap and an infill material is placed in the gap.

The system comprises a thermoplastic piece shaped to conform to the portion of pipe, the piece including a heat-generating trace and the heat-generating trace including a plurality of trace leads thereon. The system further comprises a clamp for applying pressure to the piece in the vicinity of the heat-generating trace, the clamp including at least two compression bands, each of the compression bands including a plurality of power leads, each of the power leads corresponding to one of the trace leads. The power leads preferably automatically are placed into electrical contact with said trace leads when the clamp is applied over the thermoplastic piece. The piece can be used for a variety of purposes, including bundling multiple pipes together, maintaining an annular space between concentric pipes, maintaining an anode in contact with two pipes and affixing a patch or cover to one or more pipes.

摘要： A protector for a segmented anode encircles a pipeline. The protector includes an elastomeric polymeric structure molded in place at each end of the anode. The structure has the external shape of the frustrum of a cone with the base of the cone encircling the tapered end of the anode. The frustrum terminates at the diameter of the pipeline. The taper is made from a tough, fast setting polymer. In a preferred embodiment the polymer not only forms the molded taper, but fills the space between the anode segments and flows between the anode segments and the pipe. The protector adheres to the pipe as well as to the anode material, provides a corrosion barrier, and bonds the anode segments to the pipe.

摘要： A method and article for covering and sealing the exposed weld joint area of a pipeline coated with thermoplastic corrosion protective coating is the subject of this application. The article comprises a layer of thermoplastic material that is compatible with the thermoplastic coating. A layer of mastic may also be formed on one side of the thermoplastic material. A resistance wire which is preferably a strip of wire mesh is tack welded or otherwise secured to the thermoplastic strip in two parallel stretches and a third stretch that is transverse to and in contact with the first two stretches. The article is wrapped around the coated pipe with the first two stretches of the resistance wire sandwiched between the pipe coating and the thermoplastic layer of the article and the third stretch of the resistance wire sandwiched between overlapping ends of the layer of thermoplastic material. The resistance wire is then energized to produce enough heat to fuse the two thermoplastic layers into an integral unit.
