OVERVIEW: Chemco’s Ceram-chem™ system was used to rebuild the internal profile of this valve, and coat to prevent future corrosion and abrasion. In addition, RP 500 creates a slippery surface preventing hang up and blockage issues, maximising the valve’s efficiency.
INDUSTRY
ENVIRONMENT
Coke breeze – abrasive dust
SUBSTRATE
Mild Steel
CHALLENGE
Prevent abrasion, corrosion and hang up.
SCOPE
Abrasive blast to AS 1627.4, Class 2.5, 75µm profile
Mask flange faces to prevent coating in bolt holes.
Application of RS 500P to a nominal thickness of 100µm (internally and externally.
Application of RH 500 to rebuild internal profile.
Application of RP 500AR in 2 coats.
OUTCOME
A slippery surface preventing hang up and blockage issues. Other valves have now had the same treatment illustrating the asset owners confidence
