Isolates and seals pipeline valves

Page last modified
January 9 2025

IG-L is a time activated gel developed by Kinetics Controls & Innovation Ltd (KCI) to re-establish pressure retaining barriers for pipeline and process valve isolations. It is deployed as a fluid which converts to a resilient, self-bonding, pressure energized solid material after mixing and injection. IG-L is composed of a base compound, lightening agent, defoamer, and activator. When mixed for 5-10 minutes prior to deployment, IG-L undergoes a timed chemical reaction to form a gel. It has a 4 month shelf life when stored properly. 

IG-L can float to the top of a closed ball valve and displace existing fluids through leak paths. It takes high compression forces but can be easily removed by converting back to a fluid using the IG breaker solution. The cured IG-L is not sticky and does not require additional torque to reopen valves after injection. It has been successfully deployed in ball valves up to 24" diameter. IG-L allows valve isolations and leak sealing without requiring shut downs, flange breaking, or line freezing. After injection, it cures over 6-8 hours at 20°C to fully re-establish pressure barriers.
