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 …).


USES

  • SF6 leaking flange repair

APPLICATIONS

  • Electrical installation
  • Adaptable to various type of flanges
  • Temperature from -20°C to +65°C

BENEFITS

  • Online & under pressure installation
  • Non invasive system (none risk of resin intrusion into the flange)
  • Bold and screw system protection
  • Easy disassembly without damage
  • Cost effective installation (costly consignation avoided)

REFLANGEKiT® Concept

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.
