New U-press featured by energy efficiency

At Tube 2012 in Düsseldorf, Siempelkamp presented presses for the complete manufacturing process of large-diameter pipes via C-, U- and O-forming. As a single- source systems provider, Siempelkamp not only offers the machine engineering, but also demonstrates the processing technology for all three applications. Once more a new order of a long standing customer proves that Siempelkamp has set the right course with it’s C-, U- and O-forming presses. Tenaris Confab ordered an 18-MN U-press for the works in Pindamonhangaba, Brazil. It will go on line together with the O-press that had been ordered shortly before. With a new control system it is featured by particular energy efficiency. On the press U-cannings for longitudinal seam-welded pipeline pipes with diameters

of 12¾ to 48" will be manu- factured. This press will be part of a press line comprising an existing crimping-press, the new U-ing and the new 500-MN O-ing press Tenaris already ordered in March 2011. Due to the new press Tenaris is able to produce thicker-walled pipes of higher steel grades in the future. A particular feature of the Tenaris U-press is its high-energy efficiency. Pumps are provided with servo-and speed-controlled drives. The advantage of this system compared to conventional solutions is that only as much energy as actually required is applied at any time. The order also covers an innovative press control, drive systems that are arranged

The new U-press is already the second press ordered from Siempelkamp in 2011 by Tenaris

directly at the press as well as the automated tool change and automatic clamping system for tool segments. Also included in the scope of supply is the C-U-O application software developed by Siempelkamp by means of which the complete forming process can be simulated and the optimum setting parameters can be determined.
