At an operational wastewater treatment facility, sections of external steel pipework were experiencing progressive corrosion. This deterioration was driven by continuous exposure to moisture combined with challenging atmospheric conditions typical of such environments.
A protective coating solution was required to provide long-term corrosion resistance while being applied in a live, operational environment. The presence of constant surface condensation presented a key challenge, as traditional coatings may struggle to achieve adequate adhesion under damp conditions.
The application area included pipework, along with associated fittings such as bolts and flanges, all of which were exposed to the same aggressive environmental conditions. Surface preparation needed to be achievable using power tools due to access and operational constraints, while still providing a suitable profile for coating adhesion.
Surface preparation using power tools. Cleaning of prepared surfaces to remove contaminants and debris. Application of two coats of Belzona 5831 (ST Barrier) in accordance with manufacturer guidelines. Full coverage applied to pipework, including bolts and flanges. Coating selected for its suitability in condensation-prone environments
Belzona 5831 (ST Barrier) delivers long-term corrosion protection in aggressive and moisture-rich environments. It is designed to perform on damp and condensation-affected surfaces, extending asset lifespan, reducing maintenance and replacement costs.
