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

R Series tube expanders Maus Italia




The R Series with 3 rollers

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.

5R Series tube expanders Maus Italia

The 5R Series with 5 rollers

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.
