Corrosion Under Insulation Services
Corrosion under insulation (CUI) is a prevalent and destructive problem that affects many forms of thermally insulated equipment. Frequently affecting insulated carbon, low-alloy, and stainless steel parts, CUI is primarily caused by water penetration and condensed moisture through the insulation and onto the metallic part surface.
Untreated CUI can have disastrous consequences, including:
Expensive equipment damages
To keep facilities safe and efficient, Banks Industrial Group (BIG) provides CUI repair services that quickly restore and protect pipes, tanks, and vessels suffering from pitting, thin-wall defects, and loss of structural integrity.
We use a range of Belzona polymeric composites that are carefully matched to your specific needs. Application is safe and can be carried out in situ, including on hot surfaces.

Corrosion Under Insulation Services Prevent Expensive Problems
Insulated pipework and other vessels rapidly corrode if water penetrates through the insulation layer. Water ingress can occur for various reasons including:
Trapped water accumulated during construction or storage
Weakened metal cladding joints
Condensation formation due to temperature fluctuations
If untreated, the corrosion can cause vessel failure and many other dangerous, expensive problems.
To repair and prevent CUI, Banks Industrial Group uses Belzona epoxy coatings and repair composites. Belzona materials are versatile, strong, and can be applied with minimal work disruptions. Once applied, Belzona provides durable CUI protection that outlasts conventional repairs.
Belzona’s other positive properties include:
Heat-activated curing for equipment repairs during operation
High adhesion with minimal preparations for faster application (no blast cleaning or profiling necessary)
Solvent-free construction for minimal health and safety risks
Resistance against chemicals and heat for protection in temperatures up to 150°C (302°F)
