Online Repair for SF6 Leaking Flange

SF6 Gas Leak Repair with EMT

Industry: Power T&D

Application: SF6 Leaking Flange

Customer: UK Electric Utility

Date: December 2021

 

Solution: REFLANGEKiT® SF6 leak sealing technique

 

Technology: The 3X ReflangeKit® concept is based on a composite double shell system that encapsulates the leaking flange. The first shell covers and protects the flange collecting SF6 leaks. The second shell contains specific resin. An exhaust valve allows the SF6 gas to escape during resin injection. After overnight curing of the resin, the valve is closed and sealed giving a 100% seal and leak free composite repair.

 

Benefits: The installation was non-invasive and did not require a power outage. Repair was completed online and under pressure. Disassembly was easy, the fix was efficient, and cost effective.

 

Deliverables: Shunts, bolt heads and flange seals are now protected. The completed repair was tested and successful – further repairs are scheduled. Another satisfied customer, and another testimonial for EMT Site Services.
