Rongxuan Submerged Deep Well Anode, Segmented Pre-fabricated Anode Body, Storage Tank Use, Pre-packed Deep Well Anode Bed, High Silicon Cast Iron Anode

Deep well anodes are typically made of silicon carbide anodes or cylindrical anodes of mixed metal oxides. After the anodes are laid, the anode trench is filled with metallurgical coke or calcined petroleum coke. Generally, they are buried below 15-20 meters and placed vertically.


Main Application: Suitable for cathodic protection of buried metallic structures in large long-distance pipelines, urban networks, hydropower projects, and areas with high surface soil resistivity. It is one of the main technologies for long-distance pipelines, urban networks, and regional protection.


Structural Features: The deep well anode system consists of a deep well anode body, deep well anode, internal guiding gas device, filling material, cable, and well casing device. The deep well anode can be made of precious metal oxide anodes or high silicon cast iron anodes as required. The precious metal oxide anode is a new type of anode with a titanium base coated with iridium, platinum, and other precious metal oxides.


Advantages: The distance between the deep well anode and the protected facility structure allows for a more even distribution of cathodic protection current; it also reduces corrosion interference with other buried metal facilities around. It boasts long service life, easy installation, and low grounding resistance.
