These anodes are dimensionally stable, long life anodes that are not consumed during the process of generating cathodic protection current. The use of iridium oxide (IrO 2) is preferred for all cathodic protection applications. othello killing his wife quote

WebFeb 20, 2024 · With 3 anodes per stanchion = 3 x 378 = 1134 total anodes. = 11.72 years anticipated life. Important Note: anodes are 3-inch x 3-inch x 72-inches, installed in 6-inch diameter holes, which are by 72-inches in length. Additionally, you install the anodes approximately 10-feet from the stanchion they’re protecting. Cathodic protection is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. A simple method of protection connects the metal to be protected to a more easily corroded "sacrificial metal" to act as the anode. The sacrificial metal then corrodes instead of the protected metal. For structures such as long pipelines, where passive galvanic cathodic protection is not adequate, an external DC electrical power source is used to … Webla fabrication et la distribution de protections cathodiques actives et passives, les travaux électriques dans les domaines du tertiaire, de l'industrie et du bâtiment. … rocket ship jamaica
