Unique Group’s On-Site Engineering division, through its Wellube brand, effectively performed the On-Line Steam Leak Sealing for Abu Dhabi Gas Liquefication Company (ADGAS). The service was performed on the 2.4 meters OD heat exchanger flange leak along the pipeline. It’s design parameters were 434 degrees Celsius at 60 bar.

ADGAS established in 1973, was the first LNG production company in the Middle East and North Africa region. It is known as a clean energy producer with a long history of reliability, expertise and a long-established tradition of environment awareness and concern. As of late, ADGAS is actively involved in the Offshore Associated Gas project and the Integrated Gas Development project, to be a stalwart in the national energy strategy of the UAE.

The engineering team at Unique Group designed and manufactured a four-piece ring clamp with a total weight of 3.14 ton. The flange gap measurements were taken after the clamp was mobilised to the site. The clamp lip was then machined to the exact size using the in-situ machining technology. Once the clamp was installed, 150 gallons of sealant was injected to fill the void creating an effective seal.

The entire operation was carried out in close coordination with ADGAS policies and procedures. The work was delivered with the highest level of competence, dedication and zeal to help ADGAS with the most viable solution and mitigate the high temperature leak.

Mr. Hassan Taher, Vice President – Plant Maintenance at ADGAS, congratulated the Unique Group team on successful completion of the project and for providing the best solution to reduce the high-pressure leak, “Completing the work on-line, Unique Group has made an extremely valuable contribution to the smooth running of the plant and avoided a costly shut down. We would like to thank Unique Group for mobilising the service at a short notice and accomplishing the task on time.”

Sahil Gandhi, Director at Unique Group’s On-Site Engineering division comments, “Our Wellube brand is widely recognised as a leader in the provision of on-site engineering services.
