Cathodic Protection systems are typically installed during original construction, upgrades, or expansions on a pipeline system in order to protect the pipeline from corrosion-causing electric currents. JRGO specialize in the design of cathodic protection systems, both galvanic and impressed current.
Galvanic protection system design includes linking a sacrificial metal anode to the structure being protected that is more reactive to the surrounding currents, thus protecting the pipeline structure.
Impressed Current systems are used when there is not enough difference between a galvanic anode and the pipeline system to generate sufficient current protection, so a rectifier is used to generate the difference which enables more current flow to the system being protected.
Cathodic Protection systems must be designed properly by design engineers in order to generate the greatest effectiveness. At JRGO, we have the distinct advantage of being able to look at each project from a design and construction perspective, and pull from each department expertise in order to design systems that will last while considering cost effective construction methods.
