The compact Mark V system expands heat exchanger tubes into tubesheets through the direct application of high internal hydraulic pressure. It is designed for use in fabricating heat exchangers for steam generation, condensation and evaporation. Designed to provide one-step high pressure expansion regardless of the tube sheet thickness, HydroSwage expanding mandrels feature a patented segmented seal support system that holds high pressures with minimal seal extrusion. Touchscreen electronic controls allow users to easily set up all process functions. Expansion history is stored and can be downloaded to an Excel spreadsheet through a USB port.
