Project Details

Sandwiched between the Engen Refinery and Mondi Paper Mill and a stone’s throw from the Durban coast, lies the Bluff Central Wastewater Pump Station. Denso ST™ Epoxy and Denso Steelcoat 500™ System were approved to provide long term corrosion prevention to the existing wastewater pipeline.

After mechanical preparation to ST2 and degreasing, a coat of Denso ST Epoxy at 250μm was applied by brush to the entire pipe surface. This was then overwrapped with the Denso Steelcoat 500 System ensuring the pipeline has all the protection required to withstand the harshest and most corrosive environment.
