Substation C SF6 Leaking Flange Repair

Problem

SF6 substation 3x leaking flanges

Repair

New cover plate repairs. 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 remains in service. Further, more complex repairs are planned as part of a contract to complete a number of SF6 flange repairs across multiple sites.

EMT provides specialist repair work for leaking SF6 assets on GIB cover plates

Application:

SF6 leak repair of flange cover plates and complex GIB/GIS fittings

  • SF6 GIS and GIB 220-400Kv flanges
  • Custom build repairs for various flange styles

Solution:

The REFLANGEKiT® double shell system encapsulates the leaking flange. The first shell, made in PVC, covers and protects the flange collecting SF6 leaks. The second, hard shell, contains specific resins. An exhaust valve allows the gas to be managed during resin injection. Following overnight curing of the resin, the valve is closed and sealed. Our composite repairs are suitable for a wide variety of flange styles from small inspection windows to cover plates and complex flange types including small bore pipework.

Benefits to the client:

Reflange kits may be installed under high pressure conditions without the need to degas the asset. With this original system, flange and bolts are protected during resin injection and disassembly, and the product can be easily removed without damage. This solution is quick and easy to fit by our skilled installers and with minimal interruption to service.

Deliverables:

  • Online and under pressure installation
  • Non-invasive system
  • Easy disassembly
  • Cost effective installation
  • Does not require power outage (subject to flange location)
  • Protects shunts, bolt heads and flange seals
  • Fast repairs at low cost
