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 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.

摘要： Communications systems are provided for use with an impressed current cathodic protection (ICCP) system having single or multiple ICCP components. A pipeline may be provided by connecting multiple pipeline sections together as an integrated pipeline where each section has an associated ICCP system. A communications signal comprising an AC signal is impressed on the pipeline and received by receivers associated with power supplies associated with each ICCP system. Upon reception of the AC signal, a controllable switch is operated within the power supplies to synchronously disconnect them from their power source and thereby enable accurate testing of the ICCP system.

摘要： A coating for a metal surface that provides excellent resistance to both electrochemical corrosion and mechanical insult is provided. The coating involves at least an inner coating that is a sacrificial anodic layer and an outer coating that is a protective dielectric material made of inorganic metal oxide. Some versions of the coating include an intermediate layer as well that serves to improve adhesion between the coatings and may provide additional galvanic protection. Although the coating can be made by a variety of methods, advanced methods of spray application are provided for making high-quality lightweight versions the coating.
