Kattex Fix - Tube locking using expansion tack expansion
Kattex Fix - Multiuse portable hydraulic tool for the locking of heat exchanger tubes using tack expansion
Maus Italia has solved the problem of centring and locking tubes to the tubesheet before orbital TIG welding during the assembly of heat exchangers.
The Kattex Fix, a Maus Italia patented product, instantly expands tubes in the tube bundle from inside, ( controlled mechanical expansion or "tack expansion" ), replacing it at the weld point.
Special setup of Kattex Fix
The Kattex Fix mechanically expands the tube, a delicate operation which pushes the tube in contact with the tube sheet hole. The expansion of the jaw is controlled by the pressure set on the hydraulic unit with the aim of:
The peculiarities of Kattex Fix
Istant
Using hydraulic drive, the Kattex Fix gives the tools an instant radial expansion guaranteeing high productivity.
Tack expansion - Controlled tube locking
Thanks to the innovative tools designed by Maus Italia's technical staff, the radially-expanded tube is centred in the tubesheet hole and is locked, giving optimal conditions for the next weld.
Controlled work times
The new dedicated TP2EQ2 hydraulic power unit integrates control of the entire work period ( expansion/permanence time and release/stop time ), allowing a high level of repeatability.
Wide-range - Wide range of application
Thanks to the two different sizes of Kattex, the Kattex Fix device allows the intervention on pipes up to 4.1/4" ( 107,95 mm ) for the production of industrial boilers.
Muti-power - Alternative power supplies
The Kattex Fix's hydraulic drive is given by using the Maus Italia TP2 series hydraulic power units in either the Electric and Pneumatic versions.
Dedicated Kattex Fix hydraulic power unit
TP2-EQ2
The Kattex-Fix is powered by a semi-automatic electric hydraulic power unit with an automatic cycle and pressure regulation for the calibration of the adhesion force of the tube to the hole wall.
"Tack expansion" - Expansion technology
The Kattex Fix, works on the inside of the tube and, thanks to the hydraulic force from its dedicated power unit, expands the locking tool ( K5PS or K12PS ) for tube expansion.
The centring of the tube in the tubesheet hole is achieved through the expansion of the tool.
The Kattex Fix can be configured with two different tools for two working modes
K5P Tool
Specific for the tube locking expansion, the tool will be positioned in the beginning of the tube sheet permitting the expansion of the tube in the first 10 – 15 mm.
K5PS Tool
Specific for the tube locking expansion, the tool will be positioned inside the tube sheet permitting the expansion of the tube without modifying the inlet of the tube.
The multipurpose Kattex Series
Maus Italia has widened the use of the Kattex series offering new solutions and innovative features.
