Kattex Fix
Hydraulic tool for pre-welding expansion tube locking in the heat exchangersMaus Italia has solved the problem of centring and locking tubes to the tubesheet before orbital TIG welding during the assembly of heat exchangers.
The KattexFix, a Maus Italia patented product, instantly expands tubes in the tube bundle from the inside, (controlled mechanical expansion or "tack expansion"), replacing it at the weld point.
The KattexFix, works on the inside of the tube and, thanks to the hydraulic force from its dedicated power unit, expands the locking tool for tube expansion. The centring of the tube in the tubesheet hole is achieved through the expansion of the tool.
- Automatic cycle
- Instant locking / Instant radial expansion guarantee high productivity
The radially-expanded tube is centred in the tubesheet hole and is locked, giving optimal conditions for the next weld
