Situación de aplicación:

Corrosion Under Insulation (CUI) on heating medium pipework.



The presence of insulation around the heating medium pipework had let to some corrosion of the pipework over a period of time. During a routine inspection it was decided that applying Belzona® 5851 whilst the pipework remained in service represented the best option to prevent future corrosion.

Rusting Steel


Método de aplicación:

The pipework was wet-blasted, allowed to dry and any residual aggregate brushed off. Some flash rusting was evident, and considered acceptable prior to application of two 250 micron coats of Belzona® 5851.


Hechos Belzona:

Belzona® 5851 was successfully used and allowed the customer to deal with an important maintenance issue without the need to remove equipment from service or wait for a future shutdown. The use of wet blasting in this instance allowed for rapid removal of the corrosion deposits, as well as ensuring that no non-visible surface contaminants, such as chlorides from the marine environment, were present.
