Problem

The client required a custom corrosion protection system for a newly constructed, single-bottom tank with no prior chime sealant protection. The goal was to mitigate corrosion risk at the tank chime and foundation interface before integrity testing and long-term operation.

Zerust Solution

ZERUST® Integrity Solutions installed a Chime Ring IDS system using ZERUST® Zerion™ FVS-S15 Corrosion Inhibitor Sleeves. Field engineers placed 82 sleeves around the tank chime, sealed them with Viscotaq EZ Wrap, and applied two layers of Uniflex 44-300 for long-term corrosion protection. PVC ports were installed into the concrete ring wall to allow for future Dry Tube IDS and ER Probe installations. All work was completed successfully with minimal issues.

Conclusion

The Chime Ring IDS and PVC pipe infrastructure installation were successfully completed. Zerust® will return to complete the Dry Tube IDS system and ER Probe installation after ongoing site repairs are finished. To maintain corrosion protection and support asset longevity, monthly ER Probe monitoring is recommended once installed.
