AC Mitigation
At Roberts Corrosion Services, LLC, we provide complete AC mitigation solutions to protect buried pipelines and metallic structures from the effects of induced alternating current (AC) interference caused by nearby power transmission lines. Our experienced field crews handle installation, inspection, monitoring, and repair of AC mitigation systems across West Virginia and throughout the United States.
Installations
We professionally install zinc ribbon and grounding mats on both existing pipeline facilities and new construction projects. Our installations are designed to safely dissipate induced AC voltage, improve personnel safety, and prevent accelerated corrosion. Each system is tailored to site conditions, soil resistivity, and pipeline design to ensure long-term protection and regulatory compliance.
Inspection
RCS offers inspection and oversight services for AC mitigation installations. We verify proper material placement, electrical continuity, and grounding effectiveness to confirm that mitigation systems are performing as designed. Our experts also provide documentation and reporting for compliance with PHMSA and industry standards.
Repairs / Monitoring
Regular AC mitigation monitoring and maintenance are essential to ensure continued protection. Our team provides periodic testing, resistance checks, and repairs for existing systems, addressing issues such as damaged ribbon, disconnected leads, or degraded decouplers. We help clients stay ahead of potential hazards and maintain safe operating conditions around high-voltage corridors.
Material
Roberts Corrosion Services maintains an inventory of AC mitigation materials to support both in-house and third-party projects. We can provide materials directly or integrate them into turnkey system installations. Contact our team to check current pricing and availability.
