Mixed Metal Oxide (MMO) anodes are widely recognized for their excellent electrochemical stability, high efficiency, and long service life. Designed for use in harsh marine and industrial environments, MMO anodes deliver superior cathodic protection by minimizing corrosion on metal structures.
MMO anodes are: rod, tube, strip, mesh:
1. Rod
size:
Anode Diameter Length (cm)
25x500 25 500
25x1000 25 1000
32x1200 32 1200
2. Tubular
size:
anode diameter Length (cm) Weight (kg) Surface area (m2)
25x500 25 500 0.55 0.039
25x1000 25 1000 1.10 0.079
32x1200 32 1200 1.40 0.121
Anode output current:
environment Maximum current density (A/m2) Lifespan (Years)
Carbon filler 50A/m2 20
Calcined petroleum coke 100A/m2 20
Fresh water 100A/m2 20
Salt water 100-300A/m2 20
Soil 100A/m2 20
Seawater 600A/m2 20
