Duisburg Tubes Production AG

Duisburg Tubes Production AG

For more than 50 years we develop and produce precise tubes made of zirconium-, titanium-, nickel-based- and other alloys for the use in such challenging industrial sectors as the nuclear and chemical industry, the food industry, the oil and gas industry as well as for several special applications. As close partner of our customers the production is solely based on the chipless forming on cold pilger mills, whose high precision guarantees close tolerances and extraordinarily high quality. The strict compliance to all security instructions and inspection regulations is an essential part of the DUISBURG TUBES PRODUCTION AG company`s principles. A total of 16.000 m² covered space is available for production, quality assurance as well as logistics. More than 150 qualified employees are working in these areas. An experienced team of engineers and technicians optimises products and processes according to customer requirements.

The industrial site Duisburg at the western edge of the Ruhr area offers excellent conditions for high-quality supplies and services.

A total of 16.000 m² covered space is available for production, quality assurance as well as logistics. More than 150 qualified employees are working in these areas. An experienced team of engineers and technicians optimises products and processes according to customer requirements.

Modern industrial buildings, which are each in an optimal way adapted to the different standards of various production steps and which are equipped with the latest building equipment and infrastructure, provide the basis for efficient production on a consistently high level.

1930: The Vereinigte Deutsche Metallwerke AG (VDM) was founded in 1930 when the Heddernheimer Kupferwerk AG and Süddeutsche Kabelwerk AG in Frankfurt were taken over by Berg-Heckmann-Selve AG in Altena.
The new company owned amongst others a plant and production site in Duisburg. With the beginning of the fifties the VDM became the leading producer and purchaser of raw, intermediate and finished products for non-iron metals and alloys worldwide.

1962: The Vereinigte Deutsche Metallwerke AG (VDM) in Duisburg conducts first tests with Zircaloy. For this purpose the equipment of the stainless steel division is used. The produced tubes are manufactured and also tested in the multi-purpose research reactor (Mehrzweckforschungsreaktor - MZFR) in Karlsruhe. This is the first cladding tube production of Zircaloy in Germany.

1968: In the course of time the VDM AG develops a special Zircaloy tube production with its own manufacturing equipment, which is exclusively used for this kind of production. The first commercial use of these cladding tubes started with the electrical power generation in the nuclear power plants 'Stade' and 'Würgassen'.

1974: Until this year the production of Zircaloy tubes belongs to the section 'Rohrzug 8' of VDM AG.

1975: VDM and KWU form a joint venture: the Nuklearrohrgesellschaft mbH (NRG), each holding the same amount of ownership shares (50% VDM and 50% KWU). The production facilities of VDM are still used as well as the industrial infrastructure.

1983: The enlargement of the production site is planned with a total of 16.000 m² under-roof area, whereof 2.000 m² are administration offices, laboratories and social facilities. In the frame of the construction works the old pilger hall is modernised, the heat treatment area and the final inspection hall as well as the administration building are newly constructed. According to the development of the nuclear industry in Germany there is a continuously rising demand for cladding tubes.

1986: Construction works are finished during summer and the relocation takes place. The new buildings are equipped with

  • mechanisation of final tube inspection
  • automatic cleaning equipment
  • pickling including used-acid recycling
  • laboratories
  • maintenance and tooling

1986: Siemens takes over NRG to expand into the nuclear cladding tube market. The company's name 'NRG' remains unchanged.

1988: In this year the export of qualification tubes starts to the US and Asian market.

1990: For the first time the 'Duplex tube' is produced and implemented into the market. At the same time production is further enlarged by a third annealing furnace.

1992: Expansion continues with the installation of new welding equipment for guide tubes. The production of guide tubes is transferred completely from Siemens' fuel assembly production in Hanau, which was closed in 1992, to NRG in Duisburg.

1994: Two additional cold pilger mills CPM 18 and one cold pilger mill CPM 50 for intermediate pilgering are installed. In the same year Liner cladding tubes are produced and introduced into the market.

1995: NRG (Nuklearrohrgesellschaft mbH) is incorporated into ANF (Advanced Nuclear Fuels GmbH), which is another Siemens subsidiary. The intention is to install a manufacturing network for the different components of the nuclear production industry. The cladding tube production in Duisburg, the structural part manufacturer in Karlstein and the nuclear fuel assembly production in Lingen are now consolidated.

2001: Advanced Nuclear Fuels GmbH becomes part of the French-German Joint Venture of Siemens (34%) and Framatome (66%).

2004: Advanced Nuclear Fuels GmbH Duisburg is qualified for the new material M5, a specific Zirconium alloy.

2005 : The name of the French partner Framatome changes to AREVA. The Joint Venture with Siemens stays on.

2010 : The installation of a new furnace leads to further production extention by higher annealing capacity.

2011: The Advanced Nuclear Fuels GmbH is now fully owned by AREVA, as Siemens sells its shares.

2014: In the scope of a complex carve-out the DUISBURG TUBES PRODUCTION AG takes the Duisburg location of the Advanced Nuclear Fuels GmbH in April 2014. DUISBURG TUBES PRODUCTION AG offers now also the production of tubes for non-nuclear applications by diversifying of its product portfolio.
