Overview
At an offshore facility in Western Australia, internal and external corrosion was discovered on a high temperature fuel gas line. A repair solution was required that could provide structural remediation and withstand high temperatures over a 20-year design life.
Scope
The line had the following specifications:
| Structure | Pipe elbow |
| Surface Preparation | ST3 |
| Design Pressure | 3.5 bar |
| Design Temperature | -6ºC - 204ºC |
| Application Temperature | 25ºC |
| Design Life | 20 years |
| Repair Length | 564mm |
| Pipe Diameter | 60.3mm |
| Damage Mechanism | Internal and external corrosion |
| Defect Details | 300 mm Circumferential (through wall) |
