converted into a continuous 14" seamless tube mill with an annual capacity of 600,000 tons, and will simultaneously be radically modernised. A 5-stand retained mandrel mill FQM™, a 3-stand extracting mill, and a new 14-stand sizing mill will replace the previously operated two pilger mills and the two subsequent sizing mills. Most of the downstream machinery will also be replaced. According to the cooperation agreement between DCT and Friedrich Kocks GmbH & Co KG, the company will again be responsible for the process, design, supply and commissioning of the 3-stand extractor and the 14-stand sizing mill. Both mills are equipped with the innovative Star Drive, featuring individual drives for every roll. The 3-roll stands are designed for a nominal roll diameter of 650mm. The extractor operates with non-adjustable stands only, whereas the sizing mill has both non-adjustable and adjustable stand types.

Important characteristics are the quick stand changing system, the inline remote controlled pass adjustment for the adjustable stands, and the quick roll changing system in the roll shop. After conversion, the new mill will produce seamless tubes with diameters ranging from 168 to 365mm OD and wall thickness of 6.28 to 37.3mm, with excellent tolerances and material characteristics in accordance with the international standards to be used in the oil and gas industry. The new mill is scheduled for start-up in 2010. Friedrich Kocks GmbH & Co KG – Germany Fax : +49 2103 54 028 Email : v.d.heiden@kocks.de Website : www.kocks.de TMK-Group – Russia
