ABSTRACT:
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.
