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.
