HFI welded steel pipe has been used successfully for decades in technically demanding applications and severe service conditions. Line pipe designed for high operating pressures ensures reliable transportation and distribution of gas, oil, water and other media. And without welded steel pipe, the exploration and extraction of essential resources would be impossible. Even in machinery and plant construction, welded steel pipe has established itself as an indispensable structural element.
Innovative research and ongoing developments have made SALZGITTER MANNESMANN LINE PIPE a byword for highest standards and comprehensive expertise in HFI welding technology. From our Hamm and Siegen locations in the industrial heartland of Germany, we maintain close contact with national and international institutes, notably the Salzgitter Mannesmann research centre, because we aim not only to continuously improve the HFI welding process but also to promote and support new product developments for the benefit of our customers.

Our development efforts focus especially on the quality and safety of welded pipe. Starting material inspection, 100 percent production monitoring using ultra-modern test methods and equipment, as well as final inspection at both works ensure that the properties of our steel pipes meet the most exacting requirements. This claim is backed by decades of experience in our own state-of-the-art laboratories and it has top priority in the production of HFI-welded steel pipe.
