Underground Pipelines – Galvanic System

Galvanic systems are commonly used on underground structures because they are cost-effective and do not require an external power source.

Reference electrodes(half-cells) - Important devices that permit measuring the potential of a metal surface exposed to an electrolyte. An example is a structure-to-soil potential measurement.

Test station - Provides access for the measurement of the effectiveness of a cathodic protection system.

High-potential magnesium anodes - Deliver consistent, low-voltage cathodic protection to the pipeline.

Exothermic welding system - Used for making electrical connections of copper wire to steel and cast iron surfaces for cathodic applications.

Wire and cable - HMWPE cathodic protection cable is a thick, polyethylene jacketed single copper conductor designed for direct earth burial and submerged installations.

Bond straps - Installed across pipe joints to decrease electrical resistance and maintain continuity along the pipeline.
