Tube preprocessing

Different services for different needs

Through our processing centre we are able to offer you numerous processing possibilities for a wide range of pipe designs. Simply get in touch! Our employees are happy to advise you and implement the optimum processing according to your wishes.


Preparing the optimum welding seam by bevelling the ends of the pipe is very important for smooth implementation of the pipe on the building site. We manufacture different bevel moulds that are specially tailored to your needs.

Sawing and punching

Receiving precise pipe lengths with very low tolerances directly from the factory saves you the time and money that would be needed to make these modifications on site. Our modern and efficient sawing centre enables us to provide you with any fixed length you desire in all of the dimensions listed in our portfolio. The option of punching holes at precisely determined points provides another opportunity to adapt the required pipes to suit your needs.

Forming sockets

Not encountered as much these days, but still very useful, is the option of incorporating welded plug sockets. In this department, we can offer you pipes with a coupled end in accordance with DIN 2460.
