NATURE OF DEFECT
The 24” line buried 10 metres below the ground, had suffered from external corrosion which led to a through wall defect. The client required a clamp application to seal the leak and an engineered composite overwrap to bring the line back up to its full design specification.
SOLUTION
Metalyte Pipeworks produced a repair method using Herculyte epoxies and sealants to inject the clamp sealing the leak and applied 60 layers of Drag- on-QUAD UHT composite system.
REPAIR METHOD
Sealants were injected into the clamp to fully arrest the leak and the substrate was prepared by shot blasting to gain a surface profile to SSP.SP11. The clamp was profiled accordingly allowing for an effective application of the composite.
