摘要： Corrosion protection of steel in concrete is provided by locating an anode assembly including both a sacrificial anode and an impressed current anode in contact with the concrete and providing an impressed current from a power supply to the anode. The impressed current anode forms a perforated sleeve surrounding a rod of the sacrificial anode material with an activated ionically-conductive filler material between. The system can be used without the power supply in sacrificial mode or when the power supply is connected, the impressed current anode can be powered to provide an impressed current system and/or to recharge the sacrificial anode from sacrificial anode corrosion products.

摘要： The metal tank portion of an electric water heater is protected against corrosion utilizing a corrosion protection system that detects a voltage potential between the sheath portion of a tank water-immersed electric heating element and the tank. In one embodiment of the corrosion protection system the sensed sheath/tank potential is utilized to enable a user of the water heater to accurately gauge the necessity of replacing a sacrificial anode extending into the tank. In another corrosion protection system, the sensed sheath/tank potential is utilized to provide impressed current cathodic protection of the tank and also to prevent dry firing of the electric water heater.

摘要： The life of a sacrificial anode for use in a pump device, such as a seawater pump, is extended, thus extending the life of a corrosion protection system of the seawater pump device. A pump device includes corrosion system including: a measurement unit located at a portion of a column pipe to be immersed into seawater; and a temperature control device located at an installation site of the pump device. In this corrosion protection system, a sacrificial anode electrically conductive with the column pipe and capable of being controlled in temperature is attached through a heating/cooling unit and a thermal conduction sheet to the column pipe. The temperature control device is configured to control, based on the temperature of the sacrificial anode measured by the measurement unit, the temperature of the sacrificial anode using the heating/cooling unit attached through the thermal conduction sheet to the sacrificial anode.

摘要： At least one corrosion protection unit is located adjacent to a region of a structure immersed in an electrolyte. Each corrosion protection unit includes a circuit for applying rectified alternating current voltage between the structure and electrodes in the electrolyte. Each corrosion protection unit includes Reference Cells to produce direct current voltage between the Reference Cells and the structure, a measuring circuit coupled to the Reference Cells for measuring the potential between the Reference Cells and the structure, and a control circuit for controlling the level of the rectified alternating current voltage in accordance with the measured potential levels. Corrosion protection units are independent of one another, so that independently established rectified alternating current voltages are applied between different regions of the structure and e first and second corrosion protection units. Alternatively, the corrosion protection units apply constant current or constant voltage instead of Reference Cell feedback control.

摘要： Systems and methods are described for controlling the current of a sacrificial anode based on the conductivity state of the water. An unregulated current of the sacrificial anode relative to the water tank is measured and a conductivity state of the water is identified based on the measured unregulated current. A maximum current limit for the sacrificial anode is determined based on the conductivity state of the water and the current of the sacrificial anode is limited such that the current does not exceed the determined maximum current limit.
