  • Composite anode, electrolyte pipe section, and method of making and forming a pipeline, and applying cathodic protection to the pipeline
    Patent number: 6238545
    Abstract: An anode is embedded in an electrolyte layer applied to the surface of a structure such as a pipe section to provide an ionic conductive path between the anode and structure to supply cathodic protection to the structure, where the natural environment may not provide a continuous electrolyte. The anode is comprised of a material normally used as a cathodic protection anode material, such as, an expanded valve metal mesh or ribbon having either an electrochemically active coating or noble metal coating, or a sacrificial anode metal alloy. The anode material is made continuous from one end of the structure to the other and may be connected to a common bus wire from one end to the other. The anode and structure to be protected are connected using wires to a DC power supply that causes cathodic protection current flow to the structure in the case of an impressed current system. No separate power supply is needed in the case of a galvanic or sacrificial anode system.
