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


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


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.


  • 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
