Corrosion Surveys

RCC has conducted thousands of corrosion surveys for clients around the globe. Our corrosion survey techniques include:

Soil and water corrosivity investigations in the field including soil or water sample collection, field and laboratory testing, analysis, evaluation, and corrosion control design
Stray direct current interference research, investigation, and mitigation
Corrosion protection system design, inspection, and checkout to include coating systems, bond cables, electrical continuity, rectifier operations, test stations, galvanic or impressed current anodes, and isolation devices
Underground pipeline coating flaw surveys for dielectrically coated pipe and close interval potential surveys (CIS)
Paint and coating testing on exposed structures (including tanks and pipes)
Electrical test methods utilizing “structure-to-soil” potentials and “line voltage drops” for evaluation of continuity, insulating joints, current drains, electrical shorts, and related system circuitry. Highly accurate location of ineffective or missing bonds on underground pipelines
Current requirement tests for selection and sizing of cathodic protection system components
Continuous corrosion monitoring and adjustment of cathodic protection systems for optimum effectiveness
Non-destructive testing including ultrasonic thickness measurements, flaw detection, and visual examination
