PCT No. PCT/GB95/00835 Sec. 371 Date Jan. 29, 1997 Sec. 102(e) Date Jan. 29, 1997 PCT Filed Apr. 12, 1995 PCT Pub. No. WO95/29275 PCT Pub. Date Nov. 2, 1995An elongate electrode, usually an anode, is provided, suitable for use in an impressed current corrosion protection system. The electrode comprises a central elongate core, usually a metal such as copper, an optional conductive polymeric composition surrounding the metal core and having a higher electrical resistivity than the core, but being in electrical contact with the core, a flexible jacket, for example, a fabric braid containing within it particulate coke, and tensioning wraps positioned around the flexible jacket. The purpose of the tensioning wraps is to compact the coke particles relative to their compaction in the absence of the tensioning wraps. |
