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.
The line had the following specifications:
|Design Pressure||3.5 bar|
|Design Temperature||-6ºC - 204ºC|
|Design Life||20 years|
|Damage Mechanism||Internal and external corrosion|
|Defect Details||300 mm Circumferential (through wall)|
