Kattex Fix - Tube locking using expansion tack expansion
Kattex Fix - Hydraulically-operated system for the locking of heat exchanger tubes using tack expansion
The Kattex Fix has an innovative system for the instant locking of tubes using a jaw expansion tool which ensures, as well as the desired position in relation to the tube sheet, the tube centering in the tube-sheet hole which is ideal for subsequent proper TIG orbital welding.
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:
Dedicated Kattex Fix hydraulic power unit
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.
With the expansion of the front jaw, the Kattex Fix mechanically expands the tube for a few millimeters in length until it is lightly fixed with the tube sheet hole, ensuring that it is fixed in the desired position ( pre-TIG orbital welding ).
The Kattex Fix can be configured with two different tools for two working modes
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.
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.
