About Eisenbau Krämer

Eisenbau Krämer GmbH (EBK) is an internationally active manufacturer of longitudinally welded, heavy-wall large-diameter steel pipes headquartered in Kreuztal-Kredenbach. Since 1921, the company has been producing steel pipes for demanding applications in the energy and industrial sectors, including line pipes, power plant pipes, process pipes, structural pipes, offshore jacket and topside pipes, as well as pipes for mechanical engineering, pressure vessels and hydraulic cylinders. The portfolio includes premium products such as high-temperature-resistant pipes (EBK POWER), cryogenic pipes (EBK CRYO), clad pipes (EBK CLAD, RollClad®), X80–X100 steel pipes, Impanded Pipes® and prefabricated pipe solutions (EBK Prefab Solutions). In addition, EBK offers precision machining of large, heavy components with outer diameters up to 6,300 mm and component weights up to 100 t. Around 400 employees produce approximately 100,000 tonnes of steel pipes per year on approx. 180,000 m² of company premises at the main plant in Kreuztal-Kredenbach and at the Recklinghausen production site, supplying customers worldwide.

History

1921
Foundation of the company; production of longitudinally welded steel pipes.
1945–1963
Construction of four modern production halls at the main plant in Kreuztal-Kredenbach for the production of heavy-wall steel pipes using cold and hot bending.
1970er
Due to the development of new underwater energy sources, the demand for heavy-wall large-diameter pipes increases; establishment of the additional production site in Recklinghausen.
First company in Germany with ISO 9001 certification for longitudinally welded steel pipes.
