Tube Industry Applications

Applications within the tube industry call for materials with both good wear resistance and good surface properties, such that the quality of the manufactured product is not compromised by contact with the tooling.

Thanks to their hardness and surface quality, Technox® 500 (MgO PSZ) and Technide® S10 (Silicon Nitride) ceramics achieve the highest ratings in tool life and tube quality when it comes to tube processing. Both Technide S10 and Technox® 500 ceramics play a key role in trouble-free and cost-efficient production in the following tube processes:

Bending and Expanding Aluminised Steel Tubes

Bending and expanding tools made from MgO PSZ, Technox® 500, are highly resistant to fracture and are have a good resistance to cold welding. The extended tool life helps to reduce set up and maintenance costs during the shaping process.

Expanding Copper Tubes

Using Technox® 500 mandrels for expanding copper tubes significantly improves tool life and can lead to a reduction or even the elimination of lubricants an enhanced efficiency of the forming process.

Tube Welding

Technide S10 and Technox 500 welding rolls are unaffected by inductive or magnetic fields during longitudinal seam welding of tubes.  The use of Technide S10 weld rolls significantly reduces customary excessive wear and in forming technology Technide Silicon Nitrides  are established or under evaluation for many application areas.
