Overview: This project aimed to restore and protect a critical component in the power generation sector. The strainer, constructed with a mild steel body and a stainless steel perforated basket, operates in a challenging seawater environment, which had caused significant localised pitting and corrosion damage over time.

Power Generation
ENVIRONMENT
Sea Water
SUBSTRATE
Mild Steel body with Stainless Steel perforated basket
CHALLENGE
Inspection of the existing rubber lining illustrated localised pitting on the internals, particularly around the sealing ring. Short turnaround time
SCOPE
Remove and Rubber lining from all surfaces using burn out oven. Machine rebates on all 4 flange faces.
Abrasive blast to AS. Application of RB300 Series in two coats where required to obtain minimum thickness of 1,000μm. Carry out QA, spark test at 8kV and DFT to confirm coating integrity.
Apply 3mm rubber as gasket and protective layer against gasket mechanical damage.
Application of 2 coat of RL500PF to all externals where not corroded. Application of 2 coats of Luxathane R G21.
Application of Caution Stencil in safety yellow in a visible area.
OUTCOME
Strainer was completed in time for re-assembly as per customer’s requirements. RB 364 will provide long term trouble free corrosion protection.
