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.
