The Corrosion That Costs You a Shutdown
When a steel flange fails in a chemical plant — especially in chloride-rich or acidic media — the cost is not just the replacement part. It is the unplanned shutdown, the environmental remediation, the overtime maintenance crew, and the lost production. Our ASME B16.5 titanium flanges carry a higher upfront cost but typically eliminate flange-related shutdowns for the lifetime of the plant.
