The Highest Quality

Our quality assurance/ quality management system documents and monitors each order from the arrival of the pipes to the delivery of the elbows.
Our checking mechanisms enable us to guarantee that every elbow in a run meets the same high standard.

We can satisfy the ever-increasing demands on materials through constant research and further development.

Our flexible production also enables us to manufacture short runs of special elbows, for example for repairs at the highest standard.

With the new heat treatment center we are able to carry out special heat treatments.

Our quality assurance uses various test processes, including:

- Tensile test at room temperature
- Hot tensile test
- Notched-bar impact test
- Magnetic particle test
- Liquid penetration test
- Ultrasonic test
- Drawing up of microsections
- Brinell hardness test

Fast shipping / special deliveries are organised by forwarding companies or shipping agencies.
