Onshore Infrastructure
Buried pipelines, gas and fluid transmission networks, and metallic foundations are exposed to soil corrosion — a heterogeneous and often poorly understood environment. The variability of soils — composition, water content, microorganisms, pollution — makes corrosion prediction and control particularly challenging. The French Corrosion Institute has recognised expertise and a unique soil laboratory to support onshore infrastructure operators in preventing and managing corrosion risk.
Our missions
- Characterise soil corrosivity and assess corrosion risks for buried infrastructure.
- Study the effectiveness of cathodic protection systems and associated coatings.
- Study the impact of the soil environment and associated coatings on cathodic protection (current demand, interference phenomena, relaxation currents, hydrogen embrittlement risks, etc.).
- Analyse complex phenomena: stray currents, differential aeration, microbially influenced corrosion.
- Provide real-time monitoring of corrosion and environmental parameters for buried infrastructure, on site or remotely.
Our services
- Soil characterisation: water content, resistivity, pH, chlorides, sulphates, texture, assessment in accordance with DIN 50929-3 and NF EN 12501-2
- Corrosion tests in natural or synthetic soils: coupons, mass loss, localised corrosion
- Cathodic disbondment tests on coatings in soil environments with controlled water content
- Cathodic protection study and design
- Long-term polarisation curves with current-off
- Assessment of microbially influenced corrosion (MIC), in partnership with Corrodys
- Real-time corrosion and environmental sensor solutions: custom ER probes, corrosion potential, redox potential, temperature, water content, galvanic coupling, differential aeration… with remote data acquisition
- On-site exposures in France and across Europe with remote monitoring
- Finite element modelling (polarisation, interference phenomena and stray currents)
