Cathodic Protection


Cathodic Protection is a method used to control the amount of corrosion that occurs on a metal surface by converting the anodic sites on metallic surfaces into cathodic by introducing electrical current from an alternate source.  One of the most common sources used are galvanic anodes, which are more active than steel. This practice is also referred to as a sacrificial system, since the galvanic anodes sacrifice themselves to protect the structural steel or pipeline from corrosion.


Step One: Hydro Vac to expose water main using keyhole technology

Step Two: Modified stud welding equipment is used to stud weld to water main

Step Three: Weld to main with ground bar and welding rod in same hole

Step Four: Complete anode install with test Station
