Pipe forming: Safe shaping instead of expensive welding

transfluid's process integration for spherical head sealing on steel and stainless steel tubes

In the automotive industry spherical heads are used as sealing and connecting elements for pressure tubes. Up to now, these sealing elements have been produced mechanically and subsequently connected with the respective tubes through welding or soldering. This process is not only cost-intensive, but can also result in weak points in the welds. Facing this challenge, transfluid Maschinenbau GmbH has developed an integrated method. Result: Cost-efficient and safe forming of spherical head systems directly to the tube.

"There are two different types of spherical heads. Round-shaped with a purely metallic sealing function, and sealing cones with a 24° cone. These can seal both metallically and/or be fitted with an O-ring", explains Gerd Nöker, CEO of transfluid.
"Our systems represent a new, efficient shaping technology and extend the scope to new rationalisation processes." The new combination machines enable not only material compression, but the surface can be also processed with high rolling precision.

Essential technical factors
For cost reasons, the wall thickness of the tubes must be correspondingly small. To be able to implement this, transfluid offers the possibility to increase the wall thickness in the area of forming – for example for stainless pipes of 8 x 1 mm to a wall thickness of 2.6 mm. Very small tolerance is allowed for the formed geometry. Our special endforming machines are therefore equipped with a controlled positioning system allowing for extremely precise shaping. This is vital especially for the rolling machine. To achieve an optimum result, it is essential that the surface on the spherical head is as smooth as possible. Here, the machine and tool technology from transfluid enables surface shaping of Rz 0.5 on spherical heads.

The cost saving is enormous: up to 45 percent. To avoid the situation when conventional methods hamper any further progress, transfluid will consequently continue investigating and developing new possibilities in process integration also in future.
