Production and maintenance of tube bundle heat exchangers

Ultra high pressure hydraulic systems for the expansion of tubes in heat exchangers

Hi-pression water tube expansion

Hydraulic expansion finds its best application in the expansion of tube bundle tubes welded to the tube-sheet. The tubes are expanded up to be in contact with the tube-sheet holes. The speed of its "single pass" execution, especially for expansion lengths exceeding 100 mm ( 4" ), replaces the traditional tube rolling.

Check out below our ultra high pressure hydraulic systems for the expansion of tubes in heat exchangers with a minimum internal diameter of 7.00mm ( 0.276" ) and our exclusive hi-tech model, the Hydrex 5003 S, for the controlled positioning of the tubes before welding ( tack expansion ) and hydraulic anchoring device of the probe during the expansion phase.
