Note:
l Coating loading may be adjusted to accommodate a specific current density or design life.
l Standard anodes are designed for a 30-year lifespan, but design lives of up to 50 years can be accommodated.
l Tubular MMO anode strings can be tailored to clients specific needs.
l Other tube diameters, such as 16mm & 32mm, are available upon request.
Advantages:
l Large specific surface area, resulting in a higher current output and lower anode grounding resistance.
l Compared to other anodes, tubular anodes can save 15-35% in installation costs.
l The unique flexibility of tubular anodes is advantageous for loading, transportation, and installation.
