Problem:<br />
This valve require the replacement specialty size gate. To reduce costs, the gate was fabricated from<br />
mild steel. Mild steel would corrode <strong>and</strong> erode quickly due to salt water operation conditions. A<br />
protective or preventative maintenance coating was required.<br />
Solution:<br />
Complete valve assembly was s<strong>and</strong>blasted to a SSPC-SP5 white metal finish. Surface areas were then<br />
chemically cleaned using Cleaner Blend 300. Cavitated, eroded areas deeper than 1/8” on the valve<br />
body were filled or repaired using Ceramic <strong>Repair</strong> Putty. Following a partial cure of Ceramic <strong>Repair</strong><br />
Putty, (4 hours), Brushable Ceramic Red was applied to the valve body <strong>and</strong> gate to a thickness of 15<br />
mils. Following a partial cure of Brushable Ceramic Red, (4 hours), a second coat of Brushable<br />
Ceramic Blue was applied, at 15 mils. Two coats of Brushable Ceramic provides a long lasting,<br />
abrasion <strong>and</strong> corrosion resistant, low co-efficient to friction, protective surface coating.
