Application
The application of flexible anodes for cathodic protection mainly involves the anti-corrosion protection of metal structures, especially those in corrosive environments. The following are specific applications of flexible anodes for cathodic protection:
Storage tanks and pipelines: In industries such as petroleum, chemical, and water treatment, a large number of storage tanks and pipelines use cathodic protection to prevent corrosion. Flexible anodes can tightly adhere to the surface of storage tanks and pipelines, providing uniform current distribution and achieving better corrosion resistance.
Bridges and building structures: Steel structures such as bridges and buildings are prone to corrosion under long-term environmental influences. Flexible anodes can be applied to the surface of these structures to prevent corrosion and improve their service life.
Hull and marine structures: The marine environment is highly corrosive and requires special protection for the hull and marine structures. The flexibility and bendability of flexible anodes enable them to adapt to the complex shapes of ship hulls and marine structures, providing effective cathodic protection.
Underground metal pipelines: Due to their location in soil environments, underground metal pipelines are susceptible to electrochemical corrosion. Flexible anodes can tightly adhere to pipelines, providing reliable cathodic protection.
Other metal equipment: In addition to the above applications, flexible anodes for cathodic protection can also be applied to other metal equipment, such as oil well pipelines, metal components in cooling systems, etc.
