摘要： A cathodic protection device enclosing a reference cell and a conductive media and having two coupon assemblies mounted, facing opposing direction, on an exterior surface thereof is disclosed. The coupon assemblies each have a disc-shaped coupon seated in a coupon jacket and are electrically coupled to a wire. The coupon jacket is formed from a blank having a first surface and an opposing second. A pocket as a recess is machined into the first surface, a groove is machined into the opposing second surface and an aperture is machined through the bottom of the pocket and opens into the groove. A disc-shaped coupon assembly was threaded through the pocket and aperture to seat the disc-shaped coupon in the pocket and a wire in the groove with the electrical junction therebetween aligned with the aperture.

摘要： In this flat extruded aluminum multi-port tube, the corrosion-resistance, at inner surfaces of a plurality of flow passages independently and parallelly extending in the tube axial direction, is effectively enhanced. In a flat extruded aluminum multi-port tube 10 formed by an extrusion by employing an aluminum tube material and an aluminum sacrificial anode material having an electrochemically lower potential than the aluminum tube material, the aluminum sacrificial anode material is exposed to form a sacrificial anode portion 18 at least in a part of an inner circumferential portion in each of the plurality of flow passages 12.

摘要： An enhanced anode includes a modulated body which improves anode current output efficiency by maximizing the surface area to increase surface area to weight ratio. A toroidally modulated embodiment of the enhanced anode enlarges surface area by 48 percent increasing current output efficiency by 48 percent, only increases weight by three percent, and improves surface/weight ratio 44 percent, compared to know cylindrical anodes. The enhanced anode is preferably made from cast iron or other suitable materials (e.g. magnesium, zinc, aluminum) as well, and the design of the improved anode is applicable to galvanic cast anodes in general. The enhanced anode is suitable for molding and casting and does not increase production costs.

摘要： A marine cathodic protection system configured to protect a metal structure exposed to seawater from corrosion. The system includes a first anode provided on or adjacent the protected metal structure at a first position. The first anode is exposed to seawater, is electrically insulated from the protected metal structure, and is formed of a metal having a greater negative potential than the protected metal. The system further includes a second anode provided on or adjacent the protected metal structure at a second position. The second anode is electrically connected to the first anode. The first position is preferably substantially submerged in said seawater such that the protected metal and the first anode cooperate to define a seawater battery configured to apply an electrical current to the second anode, the second anode thus being an impressed current anode.

摘要： Galvanic anodes and barrier corrosion control for metal pipelines, tanks, and equipment under thermal insulation includes the use of pure aluminum and aluminum alloys in fresh water at high temperatures to protect steel elements in hot water without sufficient chlorides. Sacrificial aluminum and sacrificial zinc-aluminum powders in a mixed primer provide long-term, effective corrosion control of steel under thermal insulation can be achieved in all water temperature ranges regardless of the presence of sufficient chlorides. At temperatures below 75° C., the zinc particles in the primer act to protect the substrate steel. At temperatures above 75° C., the aluminum particles in the primer, and galvanic aluminum tape protect the substrate steel in chloride free neutral pH water and also reduce the consumption of zinc particles in the primer. When the electrolyte water for CUI is sufficiently contaminated with chlorides, the aluminum particles in the primer and the galvanic aluminum become active.

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： A cathodic protection device enclosing a reference cell and a conductive media and having two coupon assemblies mounted, facing opposing direction, on an exterior surface. The coupon assemblies each have a disc-shaped coupon seated in a coupon jacket and are electrically coupled to a wire. The coupon jacket defines a pocket in a first surface and a groove in a second, opposing surface thereof. The disc-shaped coupon is seated in the pocket and the wire is seated in the groove with the electrical junction therebetween aligned with an aperture connecting the pocket to the groove. A sealing material is used to form a watertight seal between the disc-shaped coupon and the pocket and fills the groove. The device includes a hydrophilic porous member having a first surface in communication with the conductive media and a second surface in communication with an external environment.

摘要： A cathodic protection system is provided for a subterranean well casing having an enclosed upper section of the well casing being substantially shielded by a cellar from an impressed-current cathodic protection circuit passing through earth media. The impressed-current cathodic protection circuit is provided to protect an unenclosed lower section of the well casing. To protect the enclosed upper section of the well casing, a supplemental cathodic protection circuit is provided. The supplemental cathodic protection circuit is a galvanic anode cathodic protection circuit comprising the enclosed upper section of the well casing and one or more bracelet galvanic anodes being circumferentially mounted to the enclosed upper section. The enclosed upper section of the well casing and the one or more bracelet galvanic anodes are substantially surrounded by a cellar backfill, and the galvanic anode cathodic protection circuit is equally effective throughout a broad range of non-homogeneity within the cellar backfill.
