Hydrex 5003 S - Hydraulic system for expanding heat exchanger tubes
Hydrex 5003 S – "Hi-tech" ultra high pressure hydraulic system for expanding heat exchanger tubes and for the controlled positioning of the tubes before welding ( tack expansion ) and the controlled positioning of the probe during expansion
Hydraulic expansion finds its best application in the expansion of welded tubes for the fixing of the tube in the tube sheet hole, thanks to its exceptionally fast and competitive "single pass" execution, especially for expansion lengths exceeding 100 mm ( 4" ) where it replaces traditional expansion. The Hydrex 5003 S is the full-featured model of the 5003 series that Maus Italia has developed for typical use in the nuclear industry or for the processing of top-of-the-range heat exchanger tubes. The Hydrex 5003 S features:
The features that make all the difference
No "crevice corrosion"
Ultra high pressure
Up to 5000bar ( 72500 Psi )
The Hydrex 5003 S comprises:
Hydraulic power unit
trolley-mounted on pivoting wheels with 9" touch screen control panel and CCP and SAC dedicated software.
HDP-400 Probe holder
with probe insertion controller, quick coupling for probe change, integral remote control and 5m ( 16.4 Ft ) electric connection cable.
HF-600 Hydraulic gun
for positioning the tube prior to welding ( tack expansion ) providing the preconditions for correct TIG welding ( pre-welding ).
for anchoring to the adjacent tubes to support the HDP-4000 gun during expansion.
HWH-4000 Ultra-high pressure hose
5m ( 16.4 Ft ) in length for connecting the power unit to the probe.
Exclusive CCP control system
Continuous control for the ultra high pressure needed for tube expansion, designed by Maus Italia to eliminate out-of-tolerance expansions.
HDP-4001 Probe holder
Quick coupling probe holder with ergonomic aluminium handle and probe attachment in special material for high pressures.
Ergonomic, lightweight and with integrated remote control ( 24V ) for managing the beginning and the end of the cycle.
2TH-400 Hydraulic anchoring device
Hydraulic device for supporting the HDP-4001 probe holder to maintain the probe’s longitudinal position.
The high precision of the expansion position preserves the weld.
Elimination of "crevice corrosion" and welding cracks with the aid of the 2TH-400:
The double tube holder system anchors itself perfectly to the lateral tubes, ensuring a stable and constant positioning of the probe during the expansion phase.
HF-6000 Hydraulic gun Tack expansion
Portable hydraulic gun for the controlled positioning of the tube prior to welding.
The main function of this tool is the locking of the tubes in the desired position, by a approaching juxtaposing lightly with the tube sheet hole without contaminating it ( a specific requirement in the nuclear sector ), providing the preconditions for a correct TIG welding operation.
Internal tube diametersMust be between 8 mm and 30 mm ( between 0.315" and 1.181" )
Control console Hydrex 5003 S
CControl console with 9” touch screen display for intuitive control of all working parameters
Thanks to the use of a last generation touch screen control panel, the Hydrex 5003 is extremely simple to learn and use on a daily basis.
Specific tools for the Hydrex 5003 S
Quick coupling probe with fixed and variable diameter for the hydraulic expansion of tube for use with the HDP-4001 probe holder
FDP Fixed diameter probe
For the expansion of tubes with a diameter from 8,0 to 30,0 mm ( from 0.315" to 1.181" )
VDP Variable diameter probe
For the expansion of tubes with a diameter from 15,9 to 50,8 mm ( from 0.626" to 2" )
