Deep-well describes the installation form

Product information distinguishes a deep-well anode bed where the top of the anode body is more than 15 m below ground level. Actual depth and arrangement depend on protection range, soil, site and construction conditions.

Auxiliary anode directions

High-silicon cast-iron and noble-metal-oxide auxiliary anode directions may be assembled into the system. The system also needs the potentiostat, cable, backfill and monitoring interfaces.

Information for system discussion

Provide the protected asset, protection range, soil and site data, power conditions, design drawings, equipment list and the intended supply or construction boundary.

Key points

  • Potentiostat and auxiliary anode
  • Deep-well or shallow-buried anode bed
  • Cable, backfill and monitoring interfaces

Sacrificial-anode and impressed-current cathodic protection

Both routes use cathodic polarization to control corrosion, but their current source, components and project inputs are different.

What information helps start a cathodic protection project discussion?

The protected asset, operating environment, cooperation scope and available drawings or quantities are the four most useful starting inputs.

Test posts and reference electrodes: different roles in a system

Test posts organize field test and connection points; reference electrodes provide a measurement reference. They often work together in the monitoring chain.
