Online & under pressure leaking flange repair for SF6 gas
REFLANGEKiT® is a SF6 leak sealing technique for flanges applicable online and under pressure.
This patented concept has been designed, developed and tested in partnership with EDF R&D (Electricity Supplier, FRANCE). Approved by EPRI (Electric Power Research Institute, USA), it has been successfully applied on many substations ( Rte, Duke Energy, PSEG …).
Based on a double shell concept, the system protects flange and bolts during resin injection and disassembly. An exhaust valve allows the gas getting out during resin injection. After overnight curing of resin, the valve is closed and sealed.
Thanks to this system, flange and bolts are protected during resin injection and disassembly. The product can be easily removed without damage.
