of 72,000t and bends sheet plates with a length of up to 18m (59ft) and a thickness of up to 40mm (1.6"). Siempelkamp, Germany, supplied this press to Baoshan Iron & Steel Co Ltd Shanghai and put it into operation at a new plant. The first pipe produced achieved all required specifications and met the requirements of the customer. The sheet plates, which are bent into pipes, are up to 40mm (1.6") in thickness. At a width of up to 5m (16ft) and a length of 18m (59ft), such a plate would take up an area as large as a three-room apartment. The plates weigh up to 25t, which is comparable to the approximate weight of 20 passenger cars. The finished pipes have a diameter of up to 1.42m (4.7ft). Around 500,000t of steel plates can be processed on the press each year. If the weight for the heaviest pipe produced is assumed to be 25t, the capacity for one year would correspond to a pipeline length of 360km (224 miles). The eight press cylinders, which were cast, assembled and tested by Siempelkamp in Krefeld, form pipes with a pressing force of 72,000t. These cylinders are installed in a 21m (69ft) long and 13.5m (44ft) high press design. The total weight of the press is approximately 4,000t. Heavy parts such as frames and press tables were manufactured in China based on Siempelkamp drawings and under Siempelkamp supervision. They meet the contractual requirement for ‘local content’. Siempelkamp has built and upgraded presses of comparable sizes many times.

Advanced straightening machines for seamless tubes

Reika has received several orders for 6-roll-straightening machines for seamless tubes from German, Spanish and Ukrainian customers. This follows on from the development of straightening concepts for all areas of tube production.

In 2000, the Environmental Protection Agency established new emission standards for heavy-duty trucks and buses. The EPA’s stringent diesel emission limits for 2007-2010 reduce particulate matter, carbon monoxide and hydrocarbon pollution from heavy-duty highway vehicles by more than 90 per cent. The increase in governmental regulations has created a growing demand for diesel emission after-treatment products. Hess, already a leading supplier of after- treatment assembly systems for gas engine applications, has expanded its The machines are equipped with special features for seamless tube straightening such as dry straightening, scale removal, dust extraction, and special wear elements. The machines have excellent design features including solid ring frame, single drives and CNC-control. In addition, Reika has been awarded many international contracts for complete finishing lines for seamless tubes. Reika again received a high number of visitors to its Tube 2008 stand, which displayed a high-speed cutting centre. Tube 2008 was a record-breaking event.

existing equipment designs to facilitate the typically larger commercial diesel designs. Part sizes with substrates up to 13" diameter are typical, with larger sizes available for off-road and special applications. Several systems and methods are offered to assemble the converter substrate (with support mat) into a stainless steel tube or shell. These systems vary from simple manually operated stations to fully automated assembly cells for high production. Due to the various methods required to meet the individual customer preferences and product designs, Hess Industries offers a wide variety of equipment to suit many different applications. Hess Industries Inc is a global engineering firm and manufacturer of metal forming machines, cells, systems and factory automation solutions with over 30 years of experience. Hess also offers product development services including prototyping and short-run part production. Hess Industries Inc – USA Fax : +1 269 683 1775 Website : www.hessindustries.com
