Description
Proven Expertise: Experts in the detection of interference in accordance with NACE SP0169 and SP0207 standards for the protection of underground infrastructure.
Service Description
DC Interference Assessment is essential for assets located near electric traction systems, mining operations, or third-party pipelines. DC interference can cause severe localized corrosion at current leakage points. TECNA ICE specializes in collecting data from installed mitigation systems to verify their operational effectiveness, analyzing whether galvanic or forced drainage devices are fulfilling their function of protecting the coating and base metal from uncontrolled discharges.
Technical Scope
- Technical data collection at drainage stations.
- Monitoring of structure-to-ground potentials using GPS loggers.
- Analysis of static and dynamic interference.
- Evaluation of anode saturation in mitigation systems.
Operational Benefits
- Prevention of perforations caused by accelerated corrosion.
- Ensuring the service life of the cathodic protection system.
- Validation of compliance with design parameters.
- Technical support for preventive maintenance plans.
Methodology and Traceability
Our methodology is based on the synchronization of field measurements to capture temporal variations in potential. We perform technical data collection on installed mitigation systems, evaluating current flow and soil voltage gradients. This process allows us to correlate the activity of external sources with the behavior of the protected asset, providing a detailed report with recommendations for adjustments if we detect inefficiencies in interference drainage.
