Precious Metal Oxide Pre-packaged Deep Well Anodes are commonly used impressed current auxiliary anodes in cathodic protection systems, featuring convenient construction and superior performance. They support customization and can be shipped nationwide. The specific introduction is as follows:

Structural Composition: Typically consists of precious metal oxide tubular anode strings, vent pipes, coke backfill, and steel casings. The precious metal oxide anode string is generally composed of 3-4 tubular anodes fixed at the center of the steel casing, surrounded by coke backfill. The vent pipe is used to discharge gases generated by the anode reaction.

Working Principle: Through impressed current, the anode undergoes an oxidation reaction, releasing electrons. The current flows through electrolytes such as soil to the protected metal structure, making it the cathode, thereby inhibiting the metal's corrosion reaction and achieving cathodic protection.

Features and Advantages

Convenient Construction: Utilizes a factory-preassembled structure, requiring only on-site drilling, installation into the well, and cable connection. Some coke can be backfilled first, followed by lowering the anode assembly segment by segment into the well. Then, backfill the well with coke and water, and finally complete the backfilling process, significantly shortening the construction cycle.

Reduced Ground Resistance: Can be installed deep into wet soil tens or even hundreds of meters underground, effectively reducing the anode's ground resistance and enhancing the current output capacity and coverage range of the cathodic protection system.

Excellent Protection Effect: Ensures a more uniform distribution of protective current on the protected metal structure, reducing localized over-protection or under-protection phenomena, and extending the service life of the protected metal structure.

Space-Saving: All anodes are vertically stacked within a single borehole, requiring limited surface area for installation, making them suitable for areas with limited surface space.

Strong Corrosion Resistance: Precious metal oxides exhibit excellent corrosion resistance, enabling long-term stable operation even in harsh environments, with a service life of over 20 years.

Low Maintenance Costs: Due to their high current output efficiency and excellent protection effects, they can reduce the operational and maintenance costs of the cathodic protection system.

Specifications and Models: Available in various specifications, common combinations include Φ38mm1500mm, Φ50mm1500mm, and other diameters and lengths. Customization is also available based on customer requirements, such as the number of anodes, material thickness, and other parameters.
