Excessive pitting corrosion around the base and valves of diesoleum storage tanks G-16 and G-18 required urgent repair. 

​

Following a detailed survey, a system comprising one full coat of Corroguard EP followed by a coat of Corroless RF25 and a final coat of Corroless RF20 (B.P Green) was applied to the annular rings.

​

Prior to this application, a pre-treatment of Corroless MDP was applied to combat crevice corrosion in inaccessible areas and severe pitting was patch primed using Corroguard EP. 

​

Ball valves were also protected with Corroless S Corroless SHB and Corroless RF15 (Silver).
