    • Impressed Current Anodes
      • Flexible Linear AnodesLinear anode, also called flexible anode, is a kind of anode which is prepackaged in a non-woven fabric “sock” filled with calcined petroleum coke breeze — enhancing the abrasion and damage resistance. It improves the current distribution efficiency and helps prevent over-voltage problems such as hydrogen generation and associated rapid coating disbondment. Typical uses for this anode include the impressed current cathodic protection of in-plant piping, buried oil (gas) pipelines, petrochemical container, tank bottoms and other underground structures.
      • High Silicon Cast Iron Anodes
      • Mixed Metal Oxide Anodes
    • Galvanic/Sacrificial AnodesA galvanic anode, or sacrificial anode, is the main component of a galvanic cathodic protection system used to protect buried or submerged metal structures from corrosion. The anode is made from a metal with a more “active” voltage (more negative electrochemical potential) than the metal of the structure it is protecting (the cathode). The difference in potential between two metals means the sacrificial anode material corrodes in place of the structure by effectively stopping the oxidation reactions at the metal surface of the structure being protected. The materials used for sacrificial anodes are either relatively pure active metals or metal alloys. Our sacrificial anodes are generally made from one of four metals: aluminum, magnesium, zinc or iron. They are often used to protect the hulls of ships, water heaters, pipelines, distribution systems, above-ground tanks, underground tanks and refineries. No external power source is needed, making sacrificial anode systems easy to install. Sacrificial anodes are normally supplied with either lead wires or cast-in metal straps to allow for an easily installed connection to the structure being protected. The lead wires may be attached to the structure by welding or mechanical connections. The anodes in sacrificial anode CP systems must be periodically…
      • Magnesium AnodesHaving the highest driving voltage (most negative electrochemical potential) of all the materials used for sacrificial anodes, magnesium anodes are an effective and economical sacrificial anode solution used primarily in soil or aqueous environments where the electrolyte resistivity is expected to be higher than average. By creating an easier and more attractive source of oxidation, magnesium anodes prevent or slow down the rusting of steel structures that they are connected to. Magnesium anodes are widely used for cathodic protection of on-shore pipelines and fresh water vessels such as river or canal boats. At Jennings Anodes we manufacture magnesium anodes using pure magnesium ingot and our advanced casting technology to ensure the purity of the alloy is always maintained throughout the process. Our casting process allows us to avoid impurities, such as oxidation slag inclusion, and other common defects often found from the conventional hand casting techniques.
      • Aluminium AnodesAs a type of sacrificial anode, aluminum anodes are a popular choice for off-shore cathodic protection due to its low weight, simplicity of installation and ability to be cast into a variety of shapes and sizes to meet required specification. Typically, aluminum anodes are used to prevent corrosion of steel structures in seawater and fresh water. Although the voltage rate is lower than that of magnesium anodes, aluminum anodes have a much slower consumption rate, making them ideally suited for seawater applications such as marine vessels, ship hulls, ballast tanks, marine engineering, harbor facilities, subsea pipelines and offshore drilling platforms. We offer a comprehensive selection of aluminum anodes in various sizes, weights and core configurations. Currently our production capacity for aluminum anodes reaches up to 5,000 tons per year.
      • Zinc AnodesAnother form of sacrificial anode, zinc anodes are generally used in salt water where the resistivity is often lower than other applications. Being a high voltage conductor, zinc has a greater negative electrochemical potential than other similar metals when it is placed into salt water. This means current will flow at a higher rate through zinc than it does the other metals when subject to this same environment, therefore, limiting electrolysis to zinc alone. In essence, the zinc stops the oxidation reaction happening at the protected metal surface as the zinc is corroded in its place. This means that in certain situations zinc is far and away the best option as a sacrificial anode, notably when it is docked or anchored in seawater for long periods of time. In practice, zinc anodes are often positioned near and connected to the metallic components of a marine vessel that require protection from electrolysis-caused corrosion found in sea water usage, meaning they are typically used in the protection of ship hulls, boat propellers and rudders, shafts, offshore pipelines and production platforms.
      • Pure/Soft Iron AnodesThe purity of a metal determines its electrical conductivity. This is why the vast majority of electrical conducting components are made from materials that are as pure as possible. Our pure iron anode is produced using high grade raw material and frequently inspected to ensure conformity to our rigorous quality control procedures. The purer the iron, the better its oxidation behavior (scaling). Our pure iron anodes can operate effectively for the protection the copper alloys of heat exchanger, fresh water facilities, desalination plants (evaporator, brine heater) and condensers (used on marine platforms).
    • Boat AnodesThe ship is continuously in contact with water and moisture-laden winds which makes it highly susceptible to corrosion. Corrosion is one of the greatest enemies of the ship main body and its machinery — from the outer body (mainly hull) to the smallest equipment used in operations. Characterized by lightweight and high amperage output, our vessel anodes will provide excellent performance on both ocean-going vessels and river boats.
      • Hull AnodesWe offers a range of hull anodes in various types, including circular, rectangular, square, disc, pear and teardrop shapes. These hull anodes are designed to flush mount against the hulls of ships.
      • Ballast Tank AnodesThe ship’s ballast water tank is subject to galvanic corrosion, especially its internal steel structure immersed in seawater. The only way of preventing corrosion in ballast tank, when coatings become damaged or ultimately break down, is to apply sacrificial anodes.
      • Anti-fouling Anodes
    • Other Anodes
      • Water Heater AnodesOne of the most common killers of water heater is interior corrosion. The water inside the heater tank contains many destructive properties including heat and harsh minerals that can build up and eat away at the steel sidings, shortening the life of the electric water heater. Anode rod is the most important factor in preventing corrosion and leaks in water heater. The anode rod delivers electrons into the water that helps to create an environment that diverts corrosive action away from the tank walls to the anode rod. Thus, it prolongs the service life of the inner tank and the heating pipe. Water heater anode rod is typically made of either aluminum, magnesium or zinc.
      • Heat Treater AnodesAluminum heat treater anodes are sacrificial anodes suitable for installation in heat treaters, pressure vessels and other production vessels. They provide a compact solution for cathodic protection in relatively high temperature and low chloride saltwater environments.
      • Condenser Anodes
  • DSA Electrodes
    • Platinum Coated ElectrodesDue to its high conductivity and low consumption, platinum is an excellent anode material. However, taken in to account its high cost, the use of platinum alone is not common. By cladding or electroplating a thin platinum layer on a low-cost substrate, platinum use becomes a more practical solution. In addition, this can also be used to extend the effective anode surface area. For this to function the substrate material must also have the ability to form an insulating oxide film under anodic conditions. The two most commonly used substrates in this case are titanium and niobium. The electrical conductivity and corrosion resistance of niobium are superior to titanium as is the breakdown potential, which is much higher than that of titanium. However, niobium is more expensive. Titanium oxide has been reported to fail by breakdown at anodic potentials in the 10V range, while niobium films can withstand a breakdown voltage of up to 80V. Platinized titanium anodes are manufactured with a titanium base structure, in the form of either plate, rod, wire, mesh or tube (or any shape as per request).
    • Mixed Metal Oxide Coated ElectrodesAs a type of dimensionally stable anode (DSAs), our iridium-tantalum coated electrodes are insoluble titanium-based anodes with an iridium tantalum oxide coating. Owing to their light weight, good temperature resistance and high mechanical strength, the iridium-tantalum coated electrodes are highly regarded as the most economic and practical choice for use in an inorganic electrolyte such as sulfuric and nitric acids. Jennings Anodes offers a wide range of long-lasting iridium-tantalum coated electrodes with excellent durability, stable operational performance, remarkable energy efficiency and minimum plant downtime. Our iridium-tantalum coated electrodes can be fabricated in forms such as perforated plate, sheet, mesh, rod, wire or basket. These Ir-Ta titanium electrodes are widely used in copper foil production, printed circuit board manufacturing, etching solution regeneration, electrolytic organic synthesis, persulfate electrolysis, hospital sewage treatment, wastewater treatment, hydrometallurgy, industrial electroplating (Ag, Au, Rh, Cu, Zn, Ni, Sn, Cr) and many other electrochemical processes in which oxygen evolution is known to be the key anodic reaction.
    • Lead Dioxide Coated ElectrodesAs one type of the dimensionally stable anodes (DSAs), our lead dioxide coated electrodes are another form of DSAs and are comprised of the insoluble titanium-based anodes with either an α or β type lead dioxide coating. Owing to their light weight, low resistivity and high mechanical strength, lead dioxide coated electrodes are highly regarded as the optimal choice for use in high potential anodic processes; generally in the environment of high oxygen evolution overvoltage. Jennings Anodes can offer a wide range of long-lasting lead dioxide coated electrodes with stable operational performance, remarkable energy efficiency and minimum plant downtime. Our lead dioxide coated electrodes can be fabricated in forms such as perforated plate, sheet, mesh, rod, wire or basket. These PbO2 electrodes are widely used in chromium plating (that uses a chromic acid solution and other strongly acidic water solutions), chromate treatment, electrolytic recovery and extraction of non-ferrous metal in strongly acidic water solutions, oxidizing inorganic compound production, organic compound production in strongly acidic water solutions, water clarification and many other electrochemical processes in which ozone evolution is known to be the key anodic reaction.

    • Control Boxes
    • Junction BoxesJunction boxes are used to connect all the equipment in a cathodic protection systemand provide a means for easy inspection of individual anode currents. Choose fromsheet steel, stainless steel, aluminium, glass reinforced plastic (GRP) and plastic, wecan provide a range of junction boxes for all types of application.
    • Test StationsMeasurement of potential between buried structure and a reference electrode is the most frequently used test performed in the operation of a cathodic protection system. Test station is a simple method to monitor this potential in order to ensure that adequate current is being supplied to buried metallic structures. We produce a range of test stations with numerous colors, shapes and test lead configurations. They can be made from high impact strength molded plastic, cast iron and concrete. Often, the test stations are installed in remote fields, therefore its reliability and maintenance is a critical factor to a high performance cathodic protection system.
    • Power Cables
  • CP Accessories
    • Reference ElectrodesRoutine potential monitoring is an important part of cathodic protection maintenance program, an accurate, reliable, and consistent reference electrode is crucial for the potential monitoring.
