Relining of Corroded Structural areas of a Gypsum Unloading Plant



The Carbon Steel Structures of the Gypsum unloading area of a Cement Plant was heavily corroded due to the moisture content and aggressive service and operating conditions of the plant. Corrosion was prominent even after the application of a protective coating (different product) and the structures were weakening with time.

This, as a result, was drastically increasing the operations & maintenance cost for the cement plant, and very often excessively corroded structural parts were being dismantled and re-welded.



Upon assessing the situation and associated problems, Arudra identified that a thick layer of 100% solid epoxy lining would be required to protect the structural parts from the corrosive moisture intense environment.

Consequently, a 3mm thick layer of Duromar HPL - 2131 was applied on a wellprepared bristle blasted surface.

Duromar HPL - 2131 is a multi-functional 100% solid epoxy, with a uniquely modified polyamide hardener which is designed to rebuild and/or protect both steel and concrete tanks and other structures subject to severe corrosion and erosion.


It was noted that the 3 mm thick Duromar HPL - 2131 showcased strong adherence on the corroded carbon steel surface, and protected the surface thoroughly from any further corrosion/erosion related issues. Additionally, it was also noted that the smooth finish of Duromar HPL - 2131 prevented the gypsum material from sticking to the surface.
