Cathodic Protection Anode Life Cycle Calculator

Calculate Your Anode's Expected Lifespan

The total mass of the anode material.
Typical values: Magnesium ~1100 Ah/kg, Zinc ~780 Ah/kg, Aluminum ~2200 Ah/kg
The percentage of the anode material that can be effectively consumed (typically 0.80 to 0.95).
The average current the anode is expected to deliver over its lifespan.
Estimate the lifespan of sacrificial and impressed current anodes for your cathodic protection system. Our Cathodic Protection Anode Life Cycle Calculator helps engineers and technicians accurately predict anode consumption, ensuring optimal corrosion prevention for pipelines, marine structures, and underground tanks. Plan your maintenance effectively with precise anode life estimations.

Formula:

Anode Life (years) = (M × C × U) / (I × T)
Where:
M = Anode Mass (kg)
C = Anode Material's Current Capacity (Ah/kg)
U = Anode Utilization Factor (decimal, e.g., 0.85)
I = Average Current Output Required (Amperes)
T = Hours per year (8760 hours/year)
