Düker Quality Management System

Düker carries out numerous tests and analysis in their own pipe production.
Apart from metallographic tests, which serve to keep the cast iron on a uniform superior quality level, there are also tests on the ready product, such as crush strength tests on pipes or layer thickness and resistance tests on the coatings.
Furthermore, the Düker Quality Management System also contains quality-relevant regulations for the pre- and post-production departments as well as all commercial areas.

The QM System has been approved by external test institutes:

 

 

Certificate as per EN ISO 9001:2008

ISO9001-Zertifikat

In 1993, Düker was one of the first companies of the trade to be certified as per EN ISO 9001. Since then, the QM system has been continually adapted and updated to the latest requirements.
