Types Of Anode – An Overview

The Anode series includes four types of Anode and five DC current output ratings. The mixed metal oxide mmo anodes are easy to design and easy to install.

The unique Anode can be used for pipelines, tank farms, power and telephone ducts, and difficult applications. This design guide will give the engineer the few basic steps required.

Mixed Metal Oxide Mmo Anodes

Select the Type of Anode

There are four types of mixed metal oxide mmo anodes that can be used for various applications.

FBR Anode: The FBR anode is factory packaged inside a porous cloth tube with coke backfill.]

  • For pipeline application, (bare and poorly coated pipe)
  • Beneath aboveground storage tank bottoms, (both single and double bottom)
  • In congested manifold areas
  • Along steel sheet pile walls for the land side portion
  • For underground storage tanks
  • For piping in congested areas where interference needs to be avoided

GFC Anode: The GFC anode is factory packaged in a heavy duty, flexible, metal canister with coke backfill.

  • For pulling through under-the-road bores.
  • For use in directional drilling applications.
  • Where extra mechanical protection is needed for a short period of time.

HDP Anode: The HDP anode is factory packaged in a perforated, non-metallic housing (NOT packaged with coke backfill).

  • For power and telephone duct systems
  • In concrete applications. (The anode is buried in the concrete)
  • Along pipelines (coke backfill should be added)
  • In water applications such as inside tanks and for underwater structures

MESH Anode: The Mesh anode is factory packaged in a flexible plastic open-weave mesh tube (NOT packaged with coke backfill).

  • Beneath Aboveground Storage Tanks (ASTs). Can be preassembled to specific lengths and laid in concentric circles.
  • Some marine and soil applications.

The four types of anodes can be used for various applications. In some cases, more than one of the mixed metal oxide mmo anodes types can be used for the same application.

Anode Material

The primary anode in the Anode can be either mixed metal oxide or platinum/niobium/copper core. The main difference between the two types of anodes is that the platinum/niobium/copper anode can operate at higher voltages, up to 100 volts DC at anode to electrolyte interface. The mixed metal oxide, however, can only operate at outputs up to 12 volts DC.
