Corrosion
Solutions for structures that must last.
Orbis Terrarum has a highly-specialist team in the assessment, prevention, and mitigation of corrosion in metallic structures, both buried and exposed to the atmosphere.
Our approach combines advanced laboratory testing, in-situ measurements, and predictive models to ensure the durability of critical installations in sectors such as energy, infrastructure, and industry.
Corrosion in Buried Metallic Structures
We carry out comprehensive inspection and analysis campaigns, including:
- Technical inspection of buried metallic structures.
- Specialized laboratory for corrosion testing in soil and water.
- Measurement of metallic coating thickness (galvanization, ZAM, ZM, POSMAC).
- Root cause analysis of corrosion.
- Measurement of potentials and corrosion rates (µm/year) in situ and in the laboratory.
Predictive and Preventive Approach
We provide a long-term perspective that optimizes designs and reduces risks:
- Corrosivity potential maps and corrosion rates for photovoltaic plants.
- Identification of critical zones within the project.
- Monitoring plans for 3, 5, and 10 years.
- Material selection advisory: metals, metallic and organic coatings.
- Analysis of the evolution and durability of metallic coatings over time.
- Design of preventive and mitigating measures.
Atmospheric Corrosion
Specialized studies for structures exposed to the environment:
- Technical inspection of atmospheric corrosion in metallic structures.
- Measurement of coating thickness.
- In-situ tests with Wire on Bolt devices (ASTM G116-99).
- Exposure tests using tables according to ISO-9223, ISO-9224, and ISO-9226.
- Bibliographic studies and classification of corrosive environments (ISO 9223, 9224, 9226).
- Accelerated tests in climate chambers for analysis under extreme conditions.
