Resolving corrosion for Australian energy operator

Client challenge

Our client, a major Australian energy operator, was experiencing internal corrosion across multiple welds on an 18″ inert-gas header causing pinhole leaks on the duplex line. Another temporary repair method had failed and the client was keen to address the issue in a timely manner.

What we did

Within the design parameters provided by the client, our technical engineers were able to provide an ISO24817 compliant design with a 20-year design life, utilising 5-layers of the Technowrap 2K High-Ambient system. This addressed multiple pinhole leaks across each of the straight, elbow and reducer geometries.

Results

Our technicians were able to provide the engineered repair on the live-line, thus eliminating any downtime for the client. Our technicians were also able to work on each repair area simultaneously without delay, reducing the required time onboard the asset.
