EXPANDING
tube expansion technology
tube expansion controller | drive machines | tube expander | Custom 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.

tube expander s in the series BR 30
-
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.
tube expander s in the series BR 40
-
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.
tube expander , mechanical-hydraulic, of the series BR 20
-
specially designed for the use
with the tube expansion machine model NFAB-H
-
tube expander The Series 20 bearings are specifically designed for use with the mechanical-hydraulic tube expansion machine Type NFAB-H . They feature rollers parallel to the axis, ensuring full linear contact between tube, the rollers, and the mandrel. This enables cylindrical and circular roll-forming, which in turn results in extremely tight tube tube-to-head joints. Thus, the Series 20 tube expander are particularly suitable for chemical and petrochemical equipment manufacturing, where thin-walled tubes made of high-quality materials are frequently used. By using as many rollers as possible and incorporating 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, roller lengths of 40 mm, 50 mm, and 60 mm are available.

Available in different versions
-
The KA 64 series is available with a stop, while the KB 65 series features a ball-bearing stop. Both series come in standard versions with various roll widths. The KD 67 and KC 66 series were developed for simultaneous expanding and flaring (funnel-shaped expansion of the pipe protrusion). In the KD 67 series, a stop cap ensures precise formation of the flare at the pipe end.
Quick Step-tube expander BR 10
-
tube-Inner diameter: 9.0 mm to 35.0 mm
Especially suitable for thick tube sheets
-
Quick-steptube expander are particularly suitable for rolling tubes into thick tube sheets. tube expander from the Series 10 feature a body with grooves and a quick-release cap that snaps into place. This enables rapid expanding of the entire tube sheet. Quick-steptube expander are available in the standard version for tube-IDs ranging from 9.0 mm to 35.0 mm and for effective depths from 150 mm to 246 mm. Other effective depths are available upon request.
