The challenge
Storage tanks at a power plant are exposed to chemicals and temperature changes. A failed internal lining means leaks, contamination and costly downtime.
Fourteen tanks had to be blasted and recoated, internally in a confined space with solvent vapours, to the coating manufacturer specification.
Scope of works
- Confined space entry with permits, gas monitoring, ventilation and respiratory protection
- Abrasive blasting of internal and external steel surfaces to Sa 2½
- Multi-coat Jotun epoxy lining system for chemical resistance
- Dry film thickness (DFT), holiday (pinhole) testing and adhesion checks to ISO 12944
Outcome
All 14 tanks were coated and tested, protecting them against leaks and corrosion for years to come. See also our anti-corrosion painting of a metal chimney and our rope access painting services.
