Application: Switch head fitted with Hytorc Nuts CN style.
HYTORC tooling: HYTORC Nut CN style.
Old method: Traditional torquing.
Problem in old situation: Due to the fine thread in combination with a high side load with traditional torquing methods, multiple studs have galled into the tube plate where they are now stuck and the tube plate is badly damaged.
Benefits: By applying Hytorc Nuts is a side-load free and torsion-free clamping method is used, which excludes such problems in the future. The Hytorc Nut is also known as a mechanical tensioner. It is the only system in the world that is supplied pre-calibrated, whereby a repeatable accuracy of 5% can be guaranteed. All of this is achieved without the disadvantages of hydraulic tensioning.
