Substation A Project 2 SF6 Leaking Flange Repair

Problem

SF6 substation 6x leaking GIB/GIB flanges.

Repair

Composite encapsulated leak repair – GIB/GIB straight, medium 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. EMT Site Services have saved the client significant revenue and prevented SF6 leaks from entering the environment. SF6 savings for multiple clients across all projects completed to date currently stands at 1584 Kg/yr, that’s equivalent to 36,115 metric tons of Carbon Dioxide, or 4,393,148,505 smartphones charged (CO2e), or 4,063,824 gallons of car fuel (CO2e) – well done to our Site Services team, keep up the good work!

EMT DPG Digital Pressure Gauge Kit – the essential tool for pressure maintenance personnel

Ideal for SF6 installations, the EMT DPG provides accurate and repeatable pressure measurements and is the perfect reference measurement when checking pre-existing analogue pressure gauges, which may have been in-situ for many years un-calibrated. Can also be used as a third party reference during the filling and top-up process of SF6 assets, to ensure the system is filled to the correct pressure.

 

  • Can be used with a variety of pressure media
  • Suitable for demanding industrial applications
  • Versatile and economical

EMT’s products and services deliver a total SF6 management solution to ensure you have everything you need to keep your SF6 operations running smoothly.
