Flange Repairs
As electric utilities globally aim to reduce their CO2 footprints, leaking SF6 assets present challenges to carbon neutrality. SF6 gas leaks from circuit breakers are detrimental to personnel, plant and the environment; so failure to prevent, detect, manage and repair these can result in significant cost. EMT’s approach to leak management addresses all these concerns and solves leakage problems permanently utilising online SF6 flanged asset repairs.
3X REFLANGEKiT® concept is based on a double shell system which 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 SF6 gas to escape during resin injection. Following overnight curing of the resin, the valve is closed and sealed. With this original system, flange and bolts are protected during resin injection and disassembly, and the product can be easily removed without damage. Reflange kits may be installed under high pressure conditions without the need to degas the asset, providing fast, low cost repairs, with minimal power outages. Installation is performed by highly trained and certified EMT specialists.
