2 SMP International Salzgitter Mannesmann Précision Etirage plant, Vitry Le François, France Salzgitter Mannesmann Precisie B.V. plant, Helmond, Netherlands Precision steel tubes 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 water can flow 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 380 mm* and wall thicknesses from 0.2 to 25 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 efficiency from the pre-material to the finished 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.

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 specifications. Mechanical tests and technological tests (like flaring, flattening,...) 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 mm (5.9 ) of each leg (standard), over 150 mm upon request, Joule effect Hydrostatic test up to 800 bars ( psi) for radii up to 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 specifications and standards The following standards apply in bending, the subsequent examination or heat treatment.
