Repair and Rebuild of Acid Neutralization Trench Lines in Power Plant
Area of Application: Acid Neutralization Trench
Products Used: Duromar DF 1301 + DuroFil + Duromar DF-4301
Protection Against: Acidic Water Mixed with Solvents
Acid resistant tiles that were installed along the neutralization trench lines of a Thermal Power Plant had completely worn out within a span of 12 months. This as a result had caused severe corrosion across the civil & concrete areas of the DM plant, forcing the plant maintenance teams to replace and repair the acid-resistant tiles frequently. The drastic increase in downtime & maintenance costs required the plant to adopt a more bulletproof protective flooring system that would help overcome the damages incurred and ensure the smooth operation of the DM Plant.
Damaged acid Neutralization Trench lines
On inspecting the damages andassessing the problems, Arudrareckoned to redo the entire civil worksusing a 100% solid, 3-part epoxy grout(Duromar DuroFil) along with a top layerof the acid-resistant epoxy liner(Duromar DF – 4301). The existing tiles were removedthroughout the trench and the severelydamaged portions were rebuilt withReinforced Cement Concrete (RCC).
Installation of DuroFil followed by Duromar DF – 4301 successfully helped provide a solid foundation and outstanding acid/chemical resistance for the neutralization trench, covering a surface area of approximately 50 m².
This expert Duromar 100% Solid (Zero VOC) Epoxy grout & rebuild solution not only helpedsolve a range of operational & maintenance issues but also greatly helped inenhancing the Asset Life of these concrete areas exposed to aggressive chemical environments.
Arudra successfully executed this challenging installation within a span of 7 days,providing the end-user with risk-free operations for years to come.
