Industry: Oil & Gas (OILG)
Application: TCC-Tanks and Chemical Containment Areas (TCC)
Customer Location: Oil Refinery in U.K.

Belzona® 5851 (HA-Barrier)
Problem: The vessel was suffering from CUI (Corrosion Under Insulation).
An overall view of the vessel, complete with lagging, while in service. Surface preparation was carried out via wire brush and power wire-brushing tool. Belzona® 5851 is being applied via brush. Close-up of application area. Showing brush strokes after one year of service.
Outdoor condensate vessel.
The surface was prepared manually with a wire brush and a power wire brushing tool was used to remove loose particles. Belzona® 5851 was applied by brush. Once the material cured, the vessel was re-lagged.
Belzona® 5851 is heat activated (begins to cure at tempera-tures of 70°C or higher) and can be used on equipment that is in service making downtime a thing of the past.The application was last inspected in 2008 and the plant engineers found the Belzona® 5851 still to be providing excellent corrosion protection.
