Problem
SF6 substation 3x leaking GIB/GIB flanges.
Repair
Composite encapsulated leak repair – large flange, GIB/GIB straight, large resin fill. Suitable for nuclear and power plant substation installations. Adaptable to various types of flanges. Temperatures ranging from -20°C to +65°C (-4°F to +149°F).
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 resin, the valve is closed and sealed giving a 100% seal and leak free composite repair.
Benefits
- Online & under pressure installation
- Non invasive system (no risk of resin intrusion into the flange)
- Bolt and screw protection
- Easy disassembly
- Cost effective installation (costly consignation avoided)
Result
SF6 leak remediation was a success, and the flange is in service today. Another satisfied customer and another environmental win.
