Heat exchanger tube swaging machine
max. 50 000 psi (3 445 bar) | Mark V HydroSwage® Haskel International

Haskel offers a wide range of equipment designed for hydraulic expansion of heat exchanger tubes in tube sheets.

HydroSwage® is the direct application of high internal hydraulic pressure within a tube in order to form a tight joint between the tube and tube sheet. This pressure or expansive force is accurately set, measured, repeated and controlled. The pressure level can be calculated or determined empirically.

HydroSwage heat exchanger tube expansion systems utilize an intensifier to achieve swage pressure. This method has strong advantages over systems that depend on a single pump to generate the high pressure needed for tube expansion.
