8 thoughts on “ Sacrificial Anode - Matthias Urban - The Galvanic Twitch (Cassette)

  1. galvanic (sacrificial) anodes or impressed current anodes. Due to its extensive use in marine and other corrosive environments, steel is often the focus of cathodic protection. Other metals widely used for mechanical and structural applications are aluminium.
  2. Established in , Farwest Corrosion Control Company is a world-class leader in cathodic protection and corrosion control related products, solutions and services. Our product range is extensive, as you will see in this website, and our services include a wide variety of cathodic protection engineering and installation offerings.
  3. Anode size is 17 lb. Package length is 2 ft. Package diameter is ft. Anode spacing is 20 ft. Design life is 20 years. Calculations and Design: (Blue items in this example refer to the corresponding items as detailed in the companion document titled “Design of a Galvanic Anode Cathodic Protection System For a Pipeline”.
  4. Sacrificial (Galvanic) Anodes. Sacrificial Anodes. MATCOR can provide a complete line of sacrificial (also known as galvanic) anodes for all types of applications including: Underground; Marine; Internal; Industrial; The sacrificial anodes are available in a variety of metals including magnesium, zinc, aluminum and other alloys. Sacrificial.
  5. Anodico is a Houston-based producer of high quality, homogeneous Aluminum, Zinc, and Magnesium alloys. We operate the latest electromagnetic induction furnace technology to manufacture superior sacrificial anodes and specialty alloys with strict adherence to .
  6. Sacrificial anodes generally come in three metals: magnesium, aluminum, and zinc. Magnesium has the most negative electropotential of the three (see galvanic series, right) and is more suitable for on-shore pipelines where the electrolyte (soil or water) resistivity is higher.
  7. Sacrificial Anode Material. The galvanic series shows that magnesium heads the list as the most anodic metal and is widely separated from iron in the galvanic series. Magnesium coupled to iron provides sufficient galvanic potential to provide positive protection. An important feature of a sacrificial anode system is that it is inherently a safer system than impressed cathodic protection.
  8. Sacrificial anode-based cathodic protection when two or more metals are galvanically coupled is a potent electrochemical protection method (Jones, ). A coating that can polarize an exposed substrate material just a few hundred millivolts below its OCP .
