Customer Location:

Texas, USA


Application Date:

December 2014


Application Situation:

Corrosion around the flanges and bolts resulted in serious damage. The customer was looking for a practical and efficient solution to this problem. Several manufacturers were considered for the task including Belzona. Application was to be completed in situ and inspected after 6 months.



Belzona 3411 (Encapsulating Membrane)

Belzona 8411



Carbon Steel


Application Method:

The application was carried out in accordance with Belzona Know-How System Leaflet GSS-11.


Belzona Facts:

The customer chose Belzona since a competitor's solution 'oozed' out some sort of embedded corrosion inhibitor that looked like leaking oil. After a 6 month trial inspection, the Belzona coating was removed and the underlying flange was visually evaluated. The Customer was pleased with the results and decided to install the Belzona 3411 system on other facilities.
