Sleek Flush-Mounted Aluminum Anode with Flat Bar Core Insert

Galvanized steel flat bar insert with slender aluminium anode for reliable cathodic protection in submerged areas. Ideal for wind turbine foundations, MOUs, and offshore floaters.

Description

The slim aluminum anode, featuring a trapezoidal cross-section, is molded onto a galvanized steel flat bar core. This flush-mounted core can be directly fused to the surface of protected steel structures, ensuring a dependable connection.

Because the anode maintains direct contact with the protected surface, it conforms closely to the structure’s shape and minimizes resistance.

Primarily used for safeguarding external submerged areas of wind turbine foundations, MOUs (semisubs and jack-ups), and offshore floaters (FSO, FSUs, and FPSOs).

Quality Substrate Material
Manufactured using high-purity alloys with low iron content, our indium-activated flush-mounted aluminum anode is engineered to comply with ISO, NACE, and DNV standards.

Low Driving Voltage
The aluminum flush mount anode demonstrates consistent performance in seawater and electrolytes with chloride ions due to its operating potential maintained within the range of -1.05 to -1.10 volts compared to the saturated calomel electrode (SCE).

Technical Measurement Performance
Open Circuit Voltage (-V) 1.10 min.
Closed Circuit Voltage (-V) 1.05 min.
Current Capacity 1135 A.h/lbs (2500 A.h/kg)
Current Efficiency 90% min.
Consumption Rate 7.6 lbs/A·y (3.4 kg/A·y)

 

Much Lighter in Weight
The aluminum flush mount anode is more lightweight than zinc, which makes it easier to handle and install.

Customized Configurations
The slender flush-mount anodes are categorized as Short or Long based on their length-to-width ratio. Below are standard examples of flush-mount anodes, with custom configurations available upon request.
