摘要： The anode assembly for cathodic protection of offshore steel piles provides stability and protection for a sacrificial anode used in the cathodic protection of offshore steel piles, particularly in regard to the challenges presented in positioning the anode in a submerged, underwater environment. The anode assembly for cathodic protection of offshore steel piles includes a conventional sacrificial anode received within a protective housing. The housing is supported underwater by a support cable. A weight is fixed to the lower end of the support cable to anchor the lower end of the support cable on an underwater surface of a body of water when the housing and the sacrificial anode are suspended in the body of water. The upper end of the support cable is secured to an external support such that the housing and the sacrificial anode are suspended therefrom in a desired underwater position.

摘要： A sacrificial anode contains a powerful magnet which pulls it against an object comprising ferromagnetic metal and thus fastens the anode to the ferromagnetic metal. The magnet itself is encased in an electrically inert substance and thus does not corrode.

摘要： A corrosion-resistant cover system, having a corrosion-resistant cover structured and configured to be arrangeable around an object having one or more metallic surfaces that are susceptible to corrosion. The corrosion-resistant cover is operable to provide increased corrosion resistance to the object by preventing contact between the one or more metallic surfaces and ambient conditions exterior to the corrosion-resistant cover.

摘要： A single anode system used in multiple electrochemical treatments to control steel corrosion in concrete comprises a sacrificial metal that is capable to supporting high impressed anode current densities with an impressed current anode connection detail and a porous embedding material containing an electrolyte. Initially current is driven from the sacrificial metal [1] to the steel [10] using a power source [5] converting oxygen and water [14] into hydroxyl ions [15] on the steel and drawing chloride ions [16] into the porous material [2] around the anode such that corroding sites are moved from the steel to the anode restoring steel passivity and activating the anode. Cathodic prevention is them applied. This is preferably sacrificial cathodic prevention that is applied by disconnecting the power source and connecting the activated sacrificial node directly to the steel.

摘要： A device comprising an electrically conductive surface portion is provided for immersion in an electrically conductive liquid such as water. At least one load electrode is provided for supplying an electric load current into the electrically conductive liquid. Further, an electrode, e.g., one or more of the at least one load electrode acts as protection electrode. A protection current source, e.g., a resistor, is electrically coupled to the conductive surface portion and to the protection electrode for providing a protection current flowing between the electrically conductive surface portion and the electrode. Further, the protection current source is adapted for changing the protection current in response to a change in the load current.

摘要： An electrical connector for an anode has a terminal for an electric cable, at least two magnet devices for attracting the connector onto a metal structure, a plate electrically connecting the magnet devices to one another and to the terminal, and a deformable member connecting the magnet devices. When the connector connects an anode to a surface, the magnet forces draw the magnet devices against the surface in order to make up the connection. The deformable member allows relative movement of the magnet devices, permitting them to align themselves in an optimum configuration to maximise the surface area of the magnet devices that are in contact with the metal structure, providing a large electrical conduit between the connector and the cable connected to the terminal, and allowing for more reliable electrical connection between the anode and the structure.
