From a car to a construction crane, from a drill pipe to a power plant: precision steel tubes are found in many areas of life. Only steel with its elasticity, high strength and recyclability allows the building of passenger airbags, which can withstand a pressure load of 700 bar, energy tubes through which 300 °C hot wa-ter can fl ow without vapor bubbles, hydraulic units that safely boost 100 tons of oil sands at -30 °C without bursting.
Salzgitter Mannesmann Precision (SMP) is a leading manufacturer of cold drawn seamless and welded precision steel tubes in Europe.
Besides a wide delivery range of tube sizes from 1.5 to 400 mm*and wall thicknesses from 0.2 to 28.5 mm*, SMP provides extraordinary performance in consulting, sales and customer service with space for intelligent solutions. Synergy effects as a result of our integration with the Salzgitter Group ensure an outstanding effi ciency – from the pre-material to the fi nished precision steel tube.
The delivery program includes the production of seamless and welded precision steel tubes according to international standards, for applications in the automotive industry, machinery and equipment for pneumatic systems, hydraulic systems and diverse areas of energy technology.

Tests performed on straight tubesAt each manufacturing step, bent tubes are submitted to a visual and dimensional inspection. They are also submitted to Eddy current test (straight tubes) and, if requested, to other non-destructive tests in accordance with the requirements of the standards and customers’ specifi cations. Mechanical tests and technological tests (like fl aring, fl attening, ...) are performed on samples of each order/lot as per the reference standards.
Bent tubes can be submitted to the following:
Operations or tests• Stress relieving of the bend + 150 mm (5.9“) of each leg
(standard), over 150 mm upon request, Joule effect• Hydrostatic test up to 800 bars (11 603 psi) for radii up to
1 600 mm (63“), PLC controlled with interval programs/Alternative cycle
• Magnetic particle test for radii up to 500 mm (19.7“)• Wallthickness measurement by UT on the bent part• Ball passing test
Bent tubes are produced according to the following specifi cations and standardsThe following standards apply in bending, the subsequent examination or heat treatment. In addition, requirements are defi ned by customer specifi cations.
