How does Rockshield Mesh affect pipeline cathodic protection systems?
A critical feature of Rockshield Mesh is its open, porous diamond grid structure, which allows the uninhibited flow of groundwater and moisture around the entire circumference of the pipeline. This open design is vital because it ensures that cathodic protection currents, which are electrical currents passed through the ground to prevent pipe corrosion, can easily reach the steel pipe surface if a holiday or microscopic void ever forms in the primary coating. Solid plastic wraps can shield these protective electrical currents, creating a dangerous environment where hidden corrosion can thrive undetected. Because this mesh does not shield cathodic protection, pipeline integrity engineers can rest assured that their electrical monitoring and prevention systems will function perfectly.
