Over time, steel pipelines are subject to internal corrosion caused by under-deposit corrosion or the accumulation of aggressive compounds, which can compromise asset integrity and reduce flow efficiency.
In collaboration with Rescue Pipeline Services, TECMA offers an in-situ epoxy coating service, applied directly inside the pipeline without the need for excavation or external dismantling. This technology provides an effective and long-lasting solution for the rehabilitation of existing pipelines and for the protection of new installations exposed to corrosive environments, including CO₂ transportation systems and sensitive process changes.
Key Benefits
- Prevents internal corrosion, extending pipeline service life
- Direct application on pipeline sections up to 20 km, with no excavation required
- Cost-effective alternative to full pipeline replacement
- Uniform coating, including bends and weld joints
- Effective solution for CO₂ pipelines in highly corrosive environments
- Compatible with carbon steel pipelines
- Suitable for both repurposed pipelines and new applications
