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.

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.
