LHT & ISOLATION Localized Hydrostatic Testing & Isolation
Isolation Tool is a method that replaces conventional plugs and other plugging devices as vapour barriers. It provides the ability to monitor the seal of the tool and to monitor upstream pressure while venting to a safe location ensuring positive isolation through the process operations.
Localised Hydrostatic Testing enables a weld to be isolated and tested. This method uses only minute of water to complete a weld test. During the weld test procedure, the heat-affected zone as well as the flange can be pressure tested.
