Scope of application: deep well anode is used for anode for external current cathodic protection, which refers to the anode bed at the top of the anode body ≥15m from the ground, which is relatively shallow buried anode.
Deep well tubular anode is a type of sacrificial anode used in cathodic protection systems to prevent the corrosion of underground metal structures such as pipelines, storage tanks, and other metallic structures.
The deep well tubular titanium anode is installed in a deep borehole, typically several hundred feet deep, and filled with a conductive backfill material such as coke breeze or conductive polymer. The backfill material helps to improve the electrical conductivity of the soil and increase the anode efficiency.
Titanium anodes are often preferred over other materials for deep well cathodic protection systems due to their superior corrosion resistance, high current capacity, and long service life. They are particularly useful in environments with high soil resistivity or in situations where the structure being protected is located in a corrosive environment such as seawater.
The tubular anode is connected to the metal structure being protected by a cable, and a direct current (DC) voltage is applied to the system. The voltage causes the anode to corrode preferentially, generating electrons that flow through the cable to the metal structure, thereby preventing it from corroding.
Features:
1.Deep well anode can be used for cathodic protection of large long-distance pipelines, urban pipe networks, hydropower projects, buried metal structures in areas with high surface soil resistivity;
2.The deep well anode has little influence on the unprotected underground steel structure, little investment and is not restricted by the terrain;
3.Small grounding resistance, small interference, energy-saving explosion-proof, no need to excavate along the line;
4.Good protection effect, large output current, uniform current distribution, long protection distance, long service life.
1. Substrate material: titanium Gr1 or Gr2
2. Coating: Ir-Ta coating
3. Diameter: The diameter of the anode typically ranges from 25mm to 102mm.
4. Backfill material: The anode should be filled with a suitable backfill material such as calcined petroleum coke or graphite powder to provide electrical conductivity and ensure proper contact with the surrounding soil or electrolyte.
5. Design life: The anode should have a design life of at least 20 years, depending on the application and the environment.
It's important to note that these are general specifications, and the exact specifications may vary depending on the specific application and environment. It's recommended to consult with a qualified engineer or supplier for detailed specifications for your specific project.

Deep well anode installation site
Deep well tubular titanium anodes are commonly used for cathodic protection of metal structures that are prone to corrosion, such as pipelines, tanks, and ships.
In this application, the deep well tubular titanium anode is connected to a DC power source and placed in the surrounding electrolyte (e.g. soil, water, or seawater). When the DC current is applied, the anode becomes the anode of the electrochemical cell and corrodes sacrificially, while the metal structure being protected becomes the cathode and is protected from corrosion.
The deep well design of the titanium anode allows it to be inserted into a borehole or deep well and surrounded by a high-resistivity backfill material such as coke breeze or calcined petroleum coke. This ensures that the anode has a large surface area and is in close proximity to the structure being protected, providing efficient and effective corrosion protection.
