    摘要： An anode apparatus for mounting on an external surface of a concrete structure to provide cathodic protection of metal members in the concrete uses a pre-assembled body which is typically elongate carrying a longitudinal anode, which can be sacrificial or impressed current, together with a supporting material having a front face for attachment to the surface and an impermeable plastic covering material at the rear face covering the anode and the supporting material when the front face is attached to the surface of the concrete. A channel defined on the front face is arranged to receive a layer of a conformable ionically conductive adhesive material for attachment to the external surface. A distance of the edge of the covering material is arranged to be similar to a distance of the metal from the external surface such that wetting and drying effects of environmental moisture are the same for the anode as for the metal components.

    摘要： An intelligent system is provided for monitoring a subsea structure and delivering appropriate cathodic protection to desired areas of the subsea structure. According to an embodiment, the technique involves monitoring a cathodic protection potential level at an important location or locations of the subsea structure. Based on the data acquired via monitoring, a controller is able to apply voltage levels to the subsea structure so as to attain and modulate a desired cathodic protection level, e.g. a cathodic protection level within a range of about −800 mV to −950 mV (SCE). Consequently, undesirable overprotection and under protection are avoided and the subsea structure is adequately protected from corrosion while reducing undesirable production of hydrogen.

    摘要： Provided is a system and method for preventing the chemical redox reaction, and thereby, corrosion between potable water and copper piping systems, which causes pinhole leaks in the copper piping systems. A sacrificial anode, made of a material, such as a metal or metal alloy less noble than copper, e.g., iron, zinc, aluminum, magnesium, titanium, and/or alloys thereof, is electrically attached to the potable water copper piping system. Alternatively an active cathodic corrosion prevention system may be used. The active cathodic corrosion protection system is composed of an independent source of DC power, a voltage controller and a non-sacrificial grounding anode. The negative terminal of the voltage controller is connected to the potable water copper piping system. The system is maintained at a voltage and/or potential above the reduction potential of copper.

    摘要： Embodiments of systems and methods for providing cathodic protection to a fluid-containing vessel include measuring two distinct voltages at a junction box exterior to the fluid-containing vessel. The first voltage is measured across a shunt in the junction box such that a current magnitude through the shunt can be determined using Ohm's Law that is representative of a current output of one or more sacrificial anodes disposed within the fluid-containing vessel. The second voltage is measured by depressing a pushbutton of a momentary switch to open the switch and interrupt current flow through the shunt. The second voltage is representative of a voltage difference between the one or more sacrificial anodes and the a wall of the fluid-containing vessel.
