Mannesmannröhren-Werke AG was from 1908 until the liquidation after the Second World War, the name of the old Mannesmann - steel company based in Dusseldorf . In 1969 the Mannesmannröhren-Werke was re-established as a subsidiary of the Mannesmann Group. The Mannesmannröhren-Werke were thus - as a subsidiary of the Mannesmann AG , which was newly established in 1955 - one of the world's largest companies for the manufacture of steel pipes . Mannesmannröhren-Werke GmbH , which still exists today, is the management company for the operating companies of the Mannesmann division of the Salzgitter Group. They offer their customers a wide range of high-quality welded and seamless steel tubes for different areas of application. The rights to the Mannesmann brand are located here today .

Development into a steel company and National Socialism

Founded in Berlin in 1890 as a merger of several tube factories by the Remscheid brothers Max and Reinhard Mannesmann under the name Deutsch-Österreichische Mannesmannröhren-Werke AG , the administration and later the company headquarters were relocated to Düsseldorf in 1893, which was then the center of the German steel tube industry. In 1908 the company was given the new name Mannesmannröhren-Werke AG and subsequently developed beyond tube production into one of the largest German steel groups with its own steel production.

Like many German companies, Mannesmann also participated in the expropriation of Jewish property (" Aryanization ") before and during the Second World War . In 1938 Mannesmann took over the Wolf-Netter - & - Jacobi -Werke and formed the Mannesmann-Stahlblechbau-AG from it . The "Aryanization" of the French container manufacturer van Leer, who was originally in Dutch possession, was the subject of a detailed structural study by French historians. The study shows how dozens of participants from both countries and from all possible political and economic institutions worked together and against each other in this process. Ultimately, the French succeeded in preventing the complete capture by Mannesmann.

From 1940 until the end of the Second World War, the group systematically used forced labor and prisoners of war in its plants. During the Second World War, at least 623 people were interned in the Gelsenkirchen camp in Hubertusstrasse, who had to do forced labor for the Grillo Funke steel and rolling mill. The Mannesmann AG operated further camps in Schalke-Nord on König-Wilhelmstrasse where French and Ukrainians were housed. In Duisburg, the Mannesmannröhren-Werke had a large so-called Eastern labor camp with 1243 residents.

Re-establishment after the Second World War

After the Second World War, the old Mannesmann Group was disentangled by the Allies and split into the three independent companies Mannesmann AG , Consolidation Bergbau AG and Stahlindustrie und Maschinenbau AG . In 1955, for economic reasons, the three companies reunited to form a group under the management of Mannesmann AG . In 1969, on the basis of a work sharing agreement with Thyssen , the Mannesmannröhren-Werke AG was re-established under the umbrella of Mannesmann , in order to concentrate German steel pipe production there. This created one of the world's largest tube manufacturers.

In 1990, after having diversified in several technology areas, the parent company entered mobile communications and quickly developed into a leading company. At the end of the 1990s, plans began to concentrate on this promising area and to sell the other business areas.

In 1997 the Franco-German joint venture Vallourec & Mannesmann Tubes was founded, in which both partners concentrated their entire activities for seamlessly hot-finished pipes and oilfield pipes. The Mannesmannröhren-Werke were sold to Salzgitter AG in 2000 after the spectacular hostile takeover of the Mannesmann Group by the British telecommunications company Vodafone . In 2005, Salzgitter handed over its stake in the Vallourec & Mannesmann Tubes joint venture to the French company Vallourec .

The Mannesmannröhren-Werke, which has now been converted into a GmbH, mainly produces welded pipes. The large pipe plant in Mülheim has been part of the Route of Industrial Culture since 2019 .

Tubes for bicycle frame construction

Mannesmann manufactured frame tubes for bicycle frame construction from the 1980s to the beginning of the 1990s . Mannesmann supplied the pipes to the Italian company Oria, but also sold some of its pipes under its own name. Alongside Reynolds , Tange International and Columbus Tubi, Oria is still one of the leading manufacturers of frame tubes. In the 1980s, the company tried to compete with the traditional manufacturer Columbus. Oria used various steel blanks; besides Mannesmann also from other pipe manufacturers. Some of the Oria frames were labeled with the addition “A Mannesmann product” (“ Prodotto base Mannesmann ”) or Mannesmann Oria .

As with other frame tube manufacturers, tubes were produced in different quality levels, which mainly had an effect on the weight. The pipes were installed by well-known manufacturers such as Enik , Albuch Kotter in Germany ; in Italy by Francesco Moser , Guerciotti , Tommasini , Luigi Montagner , Olmo , Dancelli , Daccordi , Ciöcc and Pinarello (first frame from Oria tubing 1993).
