Abstract
A method for making a protector to prevent galvanic anodes from being accidentally knocked off a pipeline in which a mold having a frusto-conical shape is placed around each end of a segmented anode, with an opening at the top of the mold opposite a gap between anode segments, liquid components of a rapid setting elastomeric polymer are injected into the opening until all of the cavities and the gap are filled, and the polymer is allowed to set up and adhere to the anode and to the pipe.
Claims8
A method for forming a protector for a segmented anode encircling a pipeline with gaps between the anode segments which comprises
- placing a mold having a frusto-conical shape on each end of the anode with the base of the frustum around the end of the anode and the frustum terminating at the outside surface of the pipeline at a plane spaced away from the end of the anode;
- clamping the base end of each mold around the anode and clamping the other end of each mole around the pipeline to form a cavity between the mold and the pipeline at each end of the anode;
- enclosing all but one of the gaps to form cavities between the anode segments;
- positioning the one gap so it faces upward with the pipeline substantially horizontal,
- injecting a mixture of unreacted liquid components of a rapid setting elastomeric polymer into the one gap until all the cavities and the one gap are filled,
- allowing the components to react until the polymer sets up, and
- removing the mold.
