Tube Expansion System Is Designed For Rapid Heat-Exchanger Fabrication

Haskel International has released an updated HydroSwage tube-expansion system featuring new ease-of-use and data-collection features. The Mark V system is designed to provide high accuracy, speed and repeatability by expanding heat-exchanger tubes into tube sheets through the direct application of high internal hydraulic pressure.

The Mark V is suited for use in fabricating heat exchangers for steam generation, condensation and evaporation. Applications include power generation, metalworking, air conditioning, chemical processing, petroleum and oil, and paper mills.

It includes touch-screen electronic controls for set up of all process functions. Expansion history is stored and can be downloaded to an Excel spreadsheet through a USB port. Heavy-duty casters are designed to make it easy to roll the system up to the tube-sheet face to perform expansion. The intensifier is mounted into a drawer that slides out of the power unit. An optional 6 meter (20-foot) long umbilical cord allows the intensifier to be used at a distance from the power unit.

Designed to provide one-step high pressure expansion regardless of the tube sheet thickness, HydroSwage expanding mandrels feature a segmented seal support system that holds high pressures with minimal seal extrusion. Capable of expansion pressures to 50,000 PSI, the system accepts 100 to 240 VAC single-phase and requires air inlet pressure between 70 and 150 psi with a minimum of 70 scfm.
