Although it is more effective to apply it preventively, it can also protect structures with existing corrosion.\"}},{\"@type\":\"Question\",\"name\":\"What regulations govern the design of Cathodic Protection in Pipelines?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"At Procainsa, all our projects are developed under strict compliance with international standards such as ISO 15589-1 (specific for onshore steel pipeline transport systems) and the UNE-EN 12954 series of standards. These regulations ensure that the protection potential levels are adequate to prevent both generalized corrosion and the risk of overprotection.\"}},{\"@type\":\"Question\",\"name\":\"How long do sacrificial anodes last?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"It depends on the environment and the type of anode, but they are usually designed to last several years before needing replacement.\"}},{\"@type\":\"Question\",\"name\":\"Is cathodic protection better than anti-corrosion coatings and paints?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"They are complementary techniques. Cathodic protection acts electrochemically, while coatings serve as a physical barrier.\"}},{\"@type\":\"Question\",\"name\":\"Does a cathodic protection system require maintenance?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Yes, although less than other active methods, it requires regular check-ups to ensure continuous effectiveness.\"}},{\"@type\":\"Question\",\"name\":\"When is the use of sacrificial anodes preferred in pipelines?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Sacrificial anodes for pipes are the ideal solution for shorter infrastructures, sections with high-quality coatings, or areas where no external power supply is available. This galvanic system is self-managed, requires minimal maintenance, and is highly effective in mitigating localized corrosion in low to medium soil resistivity environments.\"}}]}<\/script>\n\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Control de Corrosi\u00f3n para Estructuras Met\u00e1licas La protecci\u00f3n cat\u00f3dica es una t\u00e9cnica electroqu\u00edmica dise\u00f1ada para prevenir y controlar la corrosi\u00f3n en estructuras met\u00e1licas expuestas a ambientes agresivos, como suelos h\u00famedos, agua de mar o entornos industriales con electrolitos.
