Challenge
Issue
The pipe column faces bad erosion, corrosion and barnacle issues which causes a hole to appear in the reducer area and hence leak seawater.
Goal
Repair the hole and rebuild the internal & external surface of the pipe.
Root Cause
Raw seawater causes erosion and corrosion to the Nickel Aluminium Bronze material pipe column.

Solution
Preparation
- Hot water pressure wash.
- Grit blast to Sa 2.5 with 3mil (75μm) angular profile.
Application
- Added steel mesh to the hole and plate patched on the internal & external pipe.
- Applied ARC 858 to rebuild internal and external pipe.
- Applied ARC-SD4i – 3 coats(Internal-DFT0.7-0.8mm) & 2 coats (external- DFT0.5mm).
