Application of Modified Epoxy Marine Heavy Anti-Corrosion Paint to Coating Repair of Steel Pipe Pile in Oil Terminal

Modified epoxy marine heavy anti-corrosion paint was used to repair the broken coating layer on the splash zone, tidal zone and atmospheric zone of the steel pipe piles in two berths of crude oil terminal of Huade petrochem Co, by sandblasting and knife coating method. After use for 4 years, the repaired coating was still in good condition and there was no corrosion on the steel pipe piles. It is indicated that the coating has good resistance to seawater corrosion and abrasion, and is suitable for repairing the part above tidal zone of wharf steel pipe piles.
