Abstract
A tip seal arrangement is provided for steam and gas turbines that allows the tip seals to be mounted on shrouds in such a way as to be easily replaceable while ensuring a minimum of contact between tenons and particles carried by leaking turbine fluid. The invention is practiced by multiple segments that clip to the shrouds so as to provide a full circle with a stand-up radial seal that projects outwardly from the shroud to provide a small clearance with the stationary diaphragm or casing that surrounds the rotating blades with the individual segments being relatively easy to remove and replace.
