OVERVIEW: Chemcote was engaged to provide long term anti corrosion protection to a power generation customer’s sea water valves
INDUSTRY
ENVIRONMENT
Ambient sea water at high velocity
SUBSTRATE
Mild steel Duo Chek Valves
CHALLENGE
Carry out internal and external corrosion protection to provide longest possible life
SOLUTION
Glass flake filled vinyl ester provides exceptional low moisture vapour transmission rates compared with molecular filled coatings.
SCOPE
Remove excess rubber surrounding valve seat area
Ensure 2-3mm radius is provided where sharp edges exist
Mask and protect critical valve seat area
Abrasive blast to the required standards
Apply Chem-tect RB 364 @ 800 microns
Apply Epo-Chem RL 500PF in one coat @ 150 microns total DFT
Apply 1 coat of Epo-Chem RC 500GTC Jade Green
Unmask and touch up ready for delivery
