This document describes several composite repair products from 3X Engineering, including TANKiT, REINFORCEKiT, PATCH, and REFLANGEKiT. REFLANGEKiT is a non-invasive system for repairing leaks in SF6 gas flanges online and under pressure. It works by encapsulating the flange in a double-shell system to collect leaks while resin is injected and cured, sealing the leak without disassembling equipment. REFLANGEKiT has been tested by EDF R&D and can repair flanges from -20°C to +65°C.

12. REFLANGEKiT®
is a SF6 leak sealing technique for flanges applicable online and under pressure.
REFLANGEKiT®
concept is based on a double shell system that encapsulates the leaking flange. The first soft 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.
