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

SF6 Asset Health #3

Plant availability and reliability amounts to efficiency and profitability. SF6 testing is becoming a more critical enabling technology and only by providing the right test equipment at the right time can you be certain of a successful predictive maintenance decision.

EMT offer tailored site services which cater to the needs of testing personnel in the electric utilities industry, acknowledging that key to their service provision is the availability and reliability of test equipment and quality of measurement. Our Site Services team can provide a range of hire equipment to clients who have urgent or short-term instrumentation requirements, ensuring business continuity where assets must remain operational.

SF6 test equipment and personnel when you need it


We cover shortfalls in equipment allowing you to meet customer demand for more comprehensive testing programs; larger sites with multiple test requirements; busier test periods, or as an interim measure whilst analysers may be out of commission or in re-calibration.


This service can also be used to acquire new test equipment without having to wait for capital equipment budget to be approved; or to upgrade/trial the latest technologies before purchasing.


If you are facing a staff shortage, need a larger team to meet demand, or you just need a helping hand, our Site Services team can support your SF6 testing personnel – the team are fully trained to all required standards associated with testing, analysis and topping up of compartment zones.


All provision is covered by our ISO9001 certification guaranteeing a great experience and ensuring EMT provide maximum support for minimum downtime.
