Nature of Defect
The 6” valve was suffering from severe internal salt water erosion. Several through wall defects have occurred at multiple locations around the full circumference of the valve behind the flange bolts. The client requires a repair solution that will seal the leaks and see them through to the valve change out.
Solution
Metalyte Pipeworks applied 12 layers of their Dragon composite system. Encapsulating the Tee and reducer to gain the required landing area. This would halt any further corrosion issues and build the strength back in to the line for full operational requirements.
Repair Method
The valve was hand prepped where possible to remove any loose corrosion and paint. The Titan 505 composite was then applied over the leak area. The system was injected with a combination of compounds to seal the leaks.
