A 4 metre section of this line is suffering from external corrosion resulting in low remaining wall thickness.
Nature of Defect
A 4 metre section of this line is suffering from external corrosion resulting in low remaining wall thickness. A through wall defect has previously been repaired on the elbow but requires an engineered overwrap to extend the design life.
Solution
Metalyte Pipeworks solution was to apply 4 layers of their bespoke high temperature composite system. This would halt any further corrosion issues and build the strength back in to the line for full operational requirements.
Repair Method
The full length of the line was prepared to SSP.SP11 to remove all corrosion and gain the surface profile required for the composite to adhere to.
The pipe surface then had a resin bond coat applied prior to the application of the composite. The line was then wrapped in 4 layers of High Temperature resistant composite and allowed to cure.
