A pin hole leak was identified on the weld directly below the welded sleeve. The through wall leak and localised wall loss is due to internal erosion.
Metalyte Pipeworks used their bespoke composite leak sealing system in conjunction with a range of water activated sealants. Once the leak was sealed, an engineered composite was applied over the affected area landing on to the top half of the flange. The bolts underneath remained accessible to allow the client to split the flange in the future.
