Long Term Corrosion Protection of a Saturator 

Posted On : Wednesday, July 21st, 2021 in News

Our Belarusian operation (Corrocoat AKZ) was contracted to refurbish and corrosion protect a water treatment saturator at a major Belarusian power station. The saturator was suffering from corrosion as the operating medium was water with an acidic pH. The client required a coating with excellent corrosion resistance, capable of providing protection for at least 10 years and specified that the work had to be completed during a planned 20-day shutdown.

After the saturator’s internals were blast cleaned to ISO 8501-1 Sa 2½, Polyglass VEHA was applied as a stripe coating at the weld areas, edges and joints. This was followed by Polyglass VE spray applied at a minimum DFT of 1000μm. Finally, a top coat of Fluiglide E was applied at a minimum of 300μm. The total area coated was 980 m2.

Corrocoat AKZ was the only company able to complete the contract within the time frame specified, showcasing how flexible and proactive they can be when faced with tight client schedules, with work being carried out by three teams working alternating shifts.
