ONLINE SF6 LEAK SEALING SOLUTION
FOR FLANGE REPAIR
REFLANGEKiT® is a SF6 leak sealing technique for G.I.S flanges applicable online and under pressure.
REFLANGEKiT® has been designed, developed and tested in partnership with EDF R&D (French Electricity Supplier). Various pressure tests and aging tests have been performed internally and in EDF laboratories in order to propose high quality product.
REFLANGEKiT® concept is based on a double shell system that encapsulates the leaking flange. The first shell made in PVC will cover and protect the flange and collect SF6 leaks. The second shell made in PET will contain 3X specific resin. 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 original system, flange and bolts are protected during resin injection and disassembly. The product can be easily removed without damage.
