Maus Italia is a leader in its field

Maus Italia is a world leader in the manufacture of tools and machinery for the production and maintenance of heat exchangers, condensers and boilers.

What we offer to our customers ranges from an individual special mandrel to completely automatic machinery able to perform more operations, all of which are completely designed and directly manufactured by Maus Italia.

Tube expanders

Maus Italia is a company specialized in the production and marketing of tube expanders.
The R Series, produced exclusively by Maus Italia, stands out for its expansion range, reliability and performance.

Tube expanders are tools built with heat-treated alloy steels and they are characterized by their wear- and fatigue-resistance.
They are composed by four main parts: the cage, the mandrel, the rolls and the collar.
Tube expansion operation is a cold mechanical deformation process that achieves a tight seal between the tube and the tube sheet.

The tube expander, constructed with heat-treated alloy steels that are resistant to wear and tear, is composed of four main parts: the cage, the mandrel, the rollers and the bearing collar.

The tooling process begins by introducing the tube expander, with its mandrel fully retracted, into the tube until the collar comes into contact with the tubesheet. The mandrel is then brought into contact with the rollers which rotate due to friction and, by coming into contact with the tube, move the mandrel forward. The rollers, expanded by the advance of the mandrel, compress the tube until it comes into contact with the tubesheet hole and reduce its thickness.

Tube rolling is a cold mechanical deformation process which achieves a tight coupling between the tube and the tubesheet.

The process is achieved by the expansion of the tube and a reduction in the thickness of the wall against the surface of the tubesheet hole, thanks to a special tool: the tube expander.

Selecting a tube expander is subject to knowing a number of technical parameters: the external diameter of the tube, the thickness of the tube, the length of expansion or thickness of the tubesheet and finally, the characteristics of the material to be rolled.

Tube rolling is rooted in the industrial England of the 1800s when the increase in the consumption of energy and large investments in industry and production created the need to build bigger and more diverse heat exchangers.

It is in this context that, at the end of the 1950s, Franco Agostino seized the opportunity given to him by the elderly German Albert Otto to learn the art of building tube expanders. Then, thanks to his indomitable spirit and perseverance, Agostino started up the small Italian factory that would, several years later, become Maus Italia. Today Maus Italia has achieved levels of excellence and is a world leader.

R Series tube expanders

The R Series is a complete range of tube expanders exclusively designed and manufactured by Maus Italia for the rolling of tubes in heat exchangers and boilers.

The R Series tube expanders with different adjustable depth are divided into two categories: R with 3 rollers and 5R with 5 rollers.

Thanks to their wide range, they can roll tubes from 6,35 mm up to 76,20 mm ( from 1/4″ up to 3″ ).

The R Series adjustable depth tube expanders have been designed for rolling tubes in heat exchangers and boilers.

They can be operated using Maus Italia electric or pneumatic torque-controlled rolling machines.

The 5R series tube expanders have five rollers to overcome the problems resulting from rolling thin-walled tubes, particularly those made of titanium.

These tube expanders, used for special rolling operations, use a mandrel with reduced tapering to reduce the residual stress in the expanded tubes.

Tube expanders

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.
