Coastal and process industries in Malaysia face a persistent challenge: accelerated corrosion in sea water–based Circulating Cooling Water (CWC) systems. High salinity, biological fouling, and continuous flow conditions often lead to premature degradation of pipelines, bends, headers, and fittings.
To address this growing need, Arudra Engineers Pvt. Ltd., in association with Duromar® high-performance coating systems, is now extending its corrosion repair and protection services to Malaysia.
Understanding Corrosion in Sea Water CWC Lines
Sea water CWC lines are continuously exposed to:
- Chloride-induced corrosion
- Microbiologically influenced corrosion (MIC)
- Erosion–corrosion at high-velocity zones
- Pitting and under-deposit corrosion
Over time, this results in wall thinning, leakages, and unplanned shutdowns, significantly impacting plant reliability and operating costs.
Duromar® Coating Systems for CWC Corrosion Repair
Duromar® coating systems are specifically designed for long-term corrosion resistance in aggressive sea water environments. These systems are widely used for rehabilitation and life extension of existing CWC infrastructure without full pipeline replacement.
Typical application areas include:
- Sea water CWC pipelines (carbon steel & concrete)
- Bends, reducers, and elbows
- Headers and manifolds
- Intake and discharge lines
- Above-ground and underground pipelines
Key Advantages of Duromar® for Sea Water Applications
- Excellent resistance to chlorides and saline media
- High adhesion on prepared steel and concrete substrates
- Proven erosion-corrosion resistance for high-velocity zones
- Seamless lining for reduced turbulence and fouling
- Rapid application suitable for shutdown maintenance windows
These coatings act as a barrier between the metal surface and corrosive sea water, significantly extending asset life.
Arudra Engineers – Now Supporting Malaysia
With extensive experience in CWC maintenance, corrosion repair, and protective coating applications, Arudra Engineers is now available to support Malaysian power plants, refineries, petrochemical complexes, desalination units, and coastal industries.
