Don’t settle for a short service life. Demand more from your protective coatings.
Too often, fixed plant equipment suffers from premature coating failure — leading to unplanned maintenance, shortened service cycles, and expensive repairs. The belief that a coated component can only last a single 4–6 year operating period before a turnaround is not an unavoidable reality.
In most cases, early coating failure can be traced to preventable issues, such as:
- Operating equipment beyond the coating’s functional design limits.
- Inadequate surface preparation or residual contaminants.
- Out-of-spec application or incorrect film thickness.
- Returning an uncured coating to immersion service.
When coatings fail, corrosion to exchanger tubesheets, channels, and bonnets puts equipment integrity and uptime at risk. In turn, emergency repairs during outages often come at expedited rates and with added scheduling complications.
Engineered for Extreme Conditions
Curran Coatings are designed specifically for the most demanding refinery and petrochemical cooling water services worldwide. These 100% solids epoxy systems provide:
- Immersion temperature resistance up to 365°F.
- High-adhesion performance.
- Resistance to cathodic disbondment.
By matching coating properties to all operational demands — including online steam cycling and chemical cleaning — Curran delivers longer service life and lower lifetime maintenance costs.
The Importance of Surface Preparation
Coating professionals agree: 70% of coating performance depends on surface prep. Curran’s process ensures:
- Clean-blasted steel to SSPC or NACE standards.
- Removal of all surface contaminants.
- Proper anchor profile.
- Film thickness applied exactly to spec — too thin risks early permeation, too thick risks cracking and poor inter-coat adhesion.
Even a perfectly applied coating can fail if returned to service before full cure. That’s why Curran uses controlled curing techniques — including heat lamps, warm air circulation, and, in their shop, a specialized oven that achieves full epoxy cure in just four hours. This enables fast turnaround of coated exchanger components without compromising quality.
