Hydraulic Tube Expansion & Heat Exchanger Sleeving


HydroSwage® International, LLC is the industry standard in hydraulic expansion (HydroSwaging). HydroSwaging is the method used to expand heat exchanger tubes using direct uniform hydraulic pressure to expand the tube, forming it into the tubesheet joint. This process is also used in Strain Control Sleeving where an insert, or ferrule, is installed into the parent tube over the damaged area and hydraulically expanded to maintain full contact with the parent tube and to seal the problem areas resulting in extended life of the exchanger along with substantial  cost savings. HydroSwage® International, LLC provides hydraulic expansion technology services globally.
