The Dockweiler production facility for fittings for the Dockweiler stainless steel tube systems, the manufacture of spec, Special fabrications to customer drawings, the optimization of existing products and processes, as well as our own product development have lead to a high degree of know how in manufacturing technology and quality assurance – further intensified by external training on specific subjects. This high degree of know how is reflected in the multitude of test methods and the documentation that can be individually packaged for specific customer needs. |
