Quality - Surface quality and purity 

Dockweiler AG, a recognised supplier of seamless tubes, has become an acknowledged specialist with an ultra-modern production site for pharmaceutical tubes and components as well as tubes and fittings for the gas transfer in the semiconductor industry. Over the past years the company has gained considerable technical know-how as well as profound engineering knowledge of prefabrications and optimisation of installation components, especially in the field of sterile, pure and ultra high purity production processes. 

The Dockweiler qualities are designed to meet the special requirements:

  • Semiconductor: The leading semiconductor manufacturers around the world entrust their production to Dockweiler stainless steel tubes and components. Today stainless steel tubes for any application - ranging from UHP to PCW - are available 

  • Pharmaceutical Industry / Biotechnology: Dockweiler offers different types of stainless steel tube systems that fulfil the special requirements of these markets, such as high corrosion resistance or sterilisability, in every respect. This system also includes an economical tube and fittings programme according to ASME BPE. 

  • Analytics: Analytics represents a wide-ranging and complex area of application. Standardized tubes and high purity tubes are needed among other things in medical labs, for sampling in the pharmaceutical, food, chemical industries as well as in biotechnology and for motor test benches in the automotive industry. Customied fabrication has increasingly gained importance during the past years because a maximum of functions must often be installed in a minimum of space. 

  • Photovoltaics: Dockweiler stainless steel systems as well as valves and instruments from our partner Evans Components from Portland / USA provide optimised solutions for a variety of applications, such as process gases - basic gas supply - industrial process cooling and slurry. This means that the customer can obtain all components - from high purity, electropolished and orbital welded components to economical Vic Evans Press Fittings combined with our new tube system TCC 304L - from one hand.

Along with electro-polishing factories in Asia, Sweden as well as in Germany and the long-term experience and competence in surface finishing and special manufacturing Dockweiler offers its customers optimal conditions for the implementation of their application-specific requirements.
