Commitment to Quality

Our quality standards are very high, and they apply throughout our business and in all production processes. The top quality of our products is ensured primarily by quality-conscious employees and our self-monitoring policy. Additional meticulous quality inspections are performed by foremen, technicians and engineers. For standard products such as cones, pipes etc., we use standardised dimensional data sheets. High-precision quality combined with a low overhead yields a certain price – a price to your advantage.

Our welders are also certified for submerged arc welding in accordance with DIN EN 1418. In addition, we are authorised to perform non-destructive testing (NDT) processes, i.e. magnaflux testing (MT) and dye penetrant testing (PT), in line with DIN EN ISO 9712. Ultrasonic and radiographic tests are carried out in collaboration with third-party service providers.

We have more than 50 welding procedure qualifications in accordance with DIN EN ISO 15614 and AD Bulletins for various welding procedures and composite materials, ranging from structural steel to super duplex materials.

To ensure compliance with these standards, all assemblies and parts are subjected to regular quality controls throughout the production workflow. In addition, all processes are documented in great detail.
