Corrosion Under Insulation Hard to Detect? Select Anti-Corrosion Layers During Petrochemical Aging-Plant Retrofit

Petrochemical tank with insulation cladding removed, showing CUI

Corrosion under insulation (CUI) silently thins tank and pipe walls beneath the cladding and is often found only after a leak. During the 2026–2029 petrochemical aging-plant retrofit window, proactive priming before re-insulation is the most cost-effective path.

Priming before re-insulation

JIANBANG applies JB-98 / JB-800 / JB-9618 / JB-8866 as long-term primers on external surfaces before insulation, resisting moisture, chloride and thermal cycling at the insulation boundary.

Matching the service temperature

For high-temperature lines JB-800 ultra-high-temperature coating serves up to 1200 °C; for atmospheric zones JB-9618 weather-resistant system gives salt-spray ≥1500 h and UV ≥4000 h.
