Accelerated Corrosion of over 50 mills per year has been

observed on pipelines co-located within high voltage AC power line corridors.

Above Ground Indicators of Potential AC Interference

• ROW is parallel or crosses at shallow angle to high tension AC power lines

• Swampy / moist areas

• Pipeline and power lines have a change in geometry such as point of convergence, divergence or cross each other

Below ground indicators of potential AC interference

• Medium to low resistivity soil conditions

• Good to excellent pipeline coatings

• Effective insulating flanges

Point Integrity has extensive expertise in the mitigation of AC interference and would be happy to provide more information regarding specific solutions for your company.
