            Snubber Series For Nuclear power Station

            Large- tonnage snubber

            Products Introduction:

            Large Tonnage snubber (3000KN ~ 5000KN) is a seismic supporter for steam generators and the main cooling pumps of nuclear power station. The snubbers stay on nuclear safety level, all hydraulic oil and non-metallic parts have strong radiation resistance capability, can be used for nuclear island. 

            The snubber is available to be designed and manufactured according to design specifications (including installation size) of customer.

            Mechanical snubber for Nuclear power station

            Products Introduction:


                   Mechanical snubber is a seismic support for nuclear power stations, thermal power stations, pipelines and equipment of chemical plants. During the normal conditions, mechanical snubber will move slowly when pipelines and equipment which connected with snubber shift due to the changed temperature .the resistance is low when the movement is small. In the event of an earthquake and pipe rupture accident, however, the snubber will immediately to limit the displacement of the pipes or equipments which were supported .the mechanical snubber plays a important role of seismic bracing during the whole processes. Mechanical snubber mainly constituted by ball screw nut, screw and flywheel inertia components and other components.
