No Comments on Substation B SF6 Leaking Flange Repair

Problem

SF6 substation 3x leaking GIB/GIB flanges.

Repair

Composite encapsulated leak repair – large flange, GIB/GIB straight, large resin fill. Suitable for nuclear and power plant substation installations. Adaptable to various types of flanges. Temperatures ranging from -20°C to +65°C (-4°F to +149°F).

Technology

The 3X ReflangeKit^®concept is based on a composite double shell system that encapsulates the leaking flange. The first shell covers and protects the flange collecting SF6 leaks. The second shell contains specific resin. An exhaust valve allows the SF6 gas to escape during resin injection. After overnight curing of resin, the valve is closed and sealed giving a 100% seal and leak free composite repair.

Benefits

Online & under pressure installation
Non invasive system (no risk of resin intrusion into the flange)
Bolt and screw protection
Easy disassembly
Cost effective installation (costly consignation avoided)

Result

SF6 leak remediation was a success, and the flange is in service today. Another satisfied customer and another environmental win.

SF6 Leak Management

Leaking SF6 assets? Problem solved with the Smartfill CTU

Post author By Lisa Redmond
Post date September 22, 2021

Smartfill CTU is a unique SF6 “live top up” device designed for managing SF6 leaks to ensure critical assets remain operational. Availability of skilled engineers, travel, training and increased gas usage results in higher secondary costs for utilities. The goal is to ensure assets never fail and to keep the network operational, whilst keeping logistics and costs to a minimum. The EMT Smartfill CTU achieves this goal via intelligently managed automated top-ups.
