AEL Anodes

AEL Anode Product Features

Advanced extended-life AEL Anodes offer impressed current cathodic protection systems premium features and capabilities that improve bottom line financial performance by reducing maintenance and operating costs and improving system performance over traditional anodes:

AEL Anodes are pre-cast assemblies designed for reliable, extended service life CP systems
Anode core utilizes mixed metal oxide (MMO) technology for optimal transfer of impressed current CP energy into the body of the anode
Anode body is formed from a cast block of conductive and impermeable material that protects the anode core against corrosion and provides a large, low energy density surface to efficiently transfer energy electronically to the anode backfill layer
Anode connection to the CP rectifier is through pre-assembled dual-jacketed Halar® insulated copper cable to maximize the operational lifetime of the anode and ensure sufficient current carrying capacity
The Halar cable is factory bonded to the anode using a double compression crimp and sealed in a block of resin to provide maximum robustness and prevent water penetration, further improving anode performance and longevity
Available in different options for use in different soil conditions
Available in a variety of current carrying capacities
Available In 2 x normal year Long Life or 3 x normal year Extreme Life versions
Available with a variety of economical standard electrical cable lengths or with client specific custom cable lengths
Anodes can be assembled in parallel multi-anode systems to increase CP system impressed current capacity
Anodes can be utilized in both vertical or horizontal anode beds
Anode can be used with a variety of backfill and cap materials, though the use of SAE impermeable long-life backfill is recommended for maximum operational performance
Anode does not require centering devices for installation
Anodes meet NEC and CEC requirements

AEL Anode Product Family

The family of advanced, long-life AEL Anodes is currently offered in two variations, according to the soil conditions in which they will be installed and operated:

AEL–100 Anode

The AEL–100 Anodes are designed for use in normal, non-saline, non-corrosive soils. The anode casings are molded from a specially formulated conductive material, DM-250 Conducrete®, that provides efficient electronic energy transfer to the backfill column.

AEL–200 Anode

The AEL–200 Anodes are designed for use in high-salinity and corrosive soils. To provide additional protection in these harsh soil environments, the anode casings are molded from a specially formulated impermeable carbonaceous material, SG-002. Like AEL–100 Anodes, energy transfer to the backfill column is electronic.

Product Specifications and Shipping

Anode Product Warranty

AEL anodes are warranted against failure for one year from the date of purchase. The warranty is void in the event of handling or operational abuse, such as overdriving the anode with higher than rated current levels.

Applications

The AEL Anode family has been specifically designed for use in vertical and horizontal anode beds of impressed current cathodic protection systems in the oil and gas sector, including:

Pipelines
Refineries
Tank farms
Other metal infrastructure subject to electrolytic corrosion
High-salinity and harsh soil environments (AEL-200 only)

Benefits

Longer anode life offers significantly lower maintenance and replacement costs
Available with fixed length electrical cables to reduce supply time and offer lower cost benefits of standardized production
Available in several lifetime and current ratings to fit a wide variety of application requirements
Anode design is water impermeable, reducing anode corrosion and extending anode lifetime
Anode design facilitates electronic energy transfer by lowering the energy density of the anode surface, thereby reducing out-gassing during operation
AEL-200 offers an effective solution for high salinity soil conditions that will extend performance and service life well beyond that of traditional anode products
Simplified installation, as centering devices are not required
Conforms to applicable NEC and CEC electrical code requirements
