EXPANDING
tube expanding controller | drive machines | tube expander | Special solutions
Our expanding technology is the result of many years of development and experience in the field of expanding tubes into tube sheets. Regardless of whether adhesion or contact expansion, large or small tube diameters, hard or soft material - our high-quality, versatile and durable expanding technology guarantees friction-locked tube to tube sheet joints. Innovative expanding technologies such as the hydraulic-mechanical expansion machine and customer-specific special solutions ensure that any desired task can be carried out reliably with TECHNODATA expansion technology.

Automatic tube expander of the BR 30 series
-
Tube inner diameter from 7.5 mm - 70.0 mm
wide range of application
-
Automatic tube expander of the 30 series are characterized by their wide range of applications with regard to pipe dimensions, pipe materials and pipe conditions. The tube expander are particularly suitable for use with harder materials due to their very long service life. Customer-specific special solutions can be realized thanks to flexible manufacturing options. This makes tube expander of the 30 series the most widely used tube expander.
Automatic tube expander of the BR 40 series
-
Tube inner diameter from 5.0 mm - 33.0 mm
special suitability for softer materials
-
Series 40 automatic tube expander are characterized by their particular suitability for softer materials such as copper or brass. The rolling process can be carried out at high speeds due to the designed pitch of the rolling mandrel. The standard version of the 40 series tube expander is available for Tube inner diameter from 4.8 mm to 33.0 mm. Other tube dimensions are available as special solutions on request.
Mechanical-hydraulic tube expander of the BR 20 series
-
specially designed for the use
with the tube expansion machine type NFAB-H
-
tube expander of the 20 series are specially designed for use with the mechanical-hydraulic tube expansion machine type NFAB-H. They have axially parallel rollers so that full linear contact is made between tube, rollers and mandrel. This enables cylindrical and round roll-ins, which in turn means extremely tight tube tube sheet connections. This makes tube expander series 20 particularly suitable for chemical and petrochemical apparatus engineering, where thin-walled tubes made of high-quality materials are often used. By using as many rollers as possible and using a guide sleeve (as shown above), the tube is optimally rolled in and the surface of the tube inner surface is protected. In the standard version, roll lengths of 40 mm, 50 mm and 60 mm are available.

Available in different versions
-
The KA 64 series is available with a stop, the KB 65 series with a ball bearing stop. Both series have different rolling widths in the standard version. The KD 67 and KC 66 series were developed for simultaneous expanding and flanging (funnel-shaped widening of the pipe protrusion). In the KD 67 series, a stop cap supports the exact production of the flare at the end of the pipe.
Quick-steptube expander BR 10
-
tube-Inner diameter: 9.0 mm to 35.0 mm
Especially suitable for thick tube sheets
-
Quick-stitchingtube expander are particularly suitable for rolling tubes into thick tube sheets. tube expander of the 10 series have bodies with grooves and a quick-locking cap that snaps into place. This enables rapid expanding of the entire tube sheet. The standard version of the quick-lockingtube expander is available for tube IDs from 9.0 mm to 35.0 mm and for effective depths from 150 mm to 246 mm. Other effective depths are available on request.
