Abstract: A sacrificial body mitigates cavitation damage to components within a pump. The sacrificial body is mounted in the pump so that flowing fluid passes over the sacrificial body, which causes the sacrificial body to shed electrons into the flowing fluid in the vicinity of the cavitation. The excess electrons tend to suppress hydrogen ions from releasing, which can mitigate cavitation. The sacrificial body is formed of a material having less resistance to corrosion due to the flowing fluid than the components of the pump. Needles are attached to the sacrificial body for immersion in the flowing fluid to facilitate the release of the electrons for the sacrificial body.

Abstract: A corrosion protection device (“CPD”) for inhibiting corrosion of an air compressor collection tank, and relieving the pressure in the tank when excessive condensate accumulates within the tank. A relief passage extends through the plug, and an anode seals the relief passage near the interior volume of the tank. The tank, plug and anode are all coupled in an electrically conductive relationship, and a galvanic circuit is formed when condensate collects near the bottom of the tank. The anode has a lower redox potential than steel, and is preferably made from magnesium. The anode loses electrons with less resistance than the steel tank, so the anode will be consumed through the oxidation process before the steel tank corrodes. Once the anode is consumed so that it no longer seals the relief passage, the condensate and air are discharged from the tank through the relief passage.

Abstract: Control of lead contamination in residential water supplies is accomplished by cathodic protection of lead-containing piping and lead-containing fixtures. Specifically, a partially insulated wire is inserted into lead-containing service lateral piping. Application of a DC current to the partially insulated wire causes the wire to act as an anode and transforms the walls of the pipe into the cathode, thereby protecting against corrosion. Alternatively, a sacrificial anode is inserted into a lead-containing fixture. The electrical potential generated by corrosion of this sacrificial anode transforms the walls of the fixture into a cathode thereby preventing corrosion. Carbonate scaling built-up prior to the initiation of cathodic protection may be removed by temporarily blocking the water pipe and introducing cleaning chemicals.

Abstract: A cathodic protection system utilizes dynamic control of an output from a power supply to vary an impressed current applied to a structure to be protected proportional to a measurement of stray electrical current. The current is also supplied to an anode bed in an amount sufficient to maintain the structure more negatively charged than the anode bed such that the stray electrical currents are directed away from the structure, thus avoiding electrolytic attack.

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.
