Condenser Tube Expanders - Tapered Mandrel With Adjustable Collar Thrust Assembly | Enhanced Tube Expansion Mechanism, High Precision Roll Design

We are praised for Making and Supplying of Condenser Tube Expanders in Thane, Maharashtra, India. Mandrel - A Tapered pin through the centre to which the power is attached and when advanced pushes the rolls against the tube. Rolls - A set of (3 or 5) of tapered cylindrical parts which are driven by mandrel and contact the tube wall to be expanded. The taper on the rolls is in the reverse direction and one-half the taper of the mandrel if it is a parallel roll expander. Cage - This is the expander body since it holds the mandrel and rolls in place. The slots which contain the rolls also provide expansion of the rolls. Collar Thrust Assembly - This assembly attaches to the cage and allows adjustment of the expanding depth. The thrust collar will remain stationary against the tube sheet or tube end while the cage, mandrel and rolls expand the tube. The thrust assembly is used on condenser or heat exchanger expanders, some furnace expanders and special boiler expander.
