Beyond standard: for the most demanding requirements

Our standard products meet the highest requirements for surface quality and purity. They are used in the semiconductor industry, in the pharmaceutical industry, in analytics and in other high-tech industries for the transportation of liquids and gases. Our tubes and fittings meet all common national and international standards and regulations.

Whether bright finished, pickled or electropolished and packaged in our clean room – we have the right product for every application.

Electropolished coil tube

Seamless gas supply in proven Dockweiler quality, manufactured for ultra-high-purity applications in the semiconductor industry. Thanks to an electropolished inner surface with Raavg. ≤ 0.25 µm, available up to a maximum length of 30 meters, the need for weld testing in the system and the risk of possible contamination can be minimized. This significantly increases efficiency during installation and safety for the application.
