Tenaris orders SMS Meer expander

HF welder expertise ATI Raveshwas established in 1996 to provide services to manufacturers of tube and pipe, and related industries. Improvement of quality and speed of production in factory lines is a main target of the company. The company has a valuable background in the field of vacuum tube rebuilding, and making or repairing all sections of HF welder systems. Automation and development of controls in tube mill lines is another field of activity. Ati Ravesh has been continuously monitoring the market to understand the problems and requirements of producers. The result of this effort is cooperation with about 70 per cent of factories in its domestic market. Ati Ravesh Engineering Group – Iran

Compared with solutions to date, the new development achieves a better straightening effect by over bending. Furthermore, the load on the expander tool is minimised. The system is designed for pipe diameters up to 30". For larger diameters the whole units can be separated from the machine. This also allows simple tool changing. TenarisConfab produces up to 450,000 tons of pipes per year using the UOE process. The pipe diameters range from 12 to 48" and the wall thicknesses from 6.4 to 40mm. The maximum pipe length is 12.5m. Apart from the complete mechanical and electrical equipment, SMS Meer also supplies the necessary measuring systems and process engineering.

CONFAB SA has ordered a mechanical expander with a newly developed straightener from SMS Meer, Germany, for its Pindamonhangaba tube mill near São Paulo, Brazil. The “Advanced Geometry Technology – AGT ® ” allows calibration and straightening of longitudinally welded pipes with small diameters and large wall thicknesses precisely on a single machine. Such pipes are required for offshore pipelines laid in deep sea waters. With AGT ® , SMS Meer can offer a flexible and efficient solution for the straightening of large-diameter pipes that have been bent by heat input during SAW welding. For the first time, selective straightening of the pipes can be carried out in all directions during expanding, eliminating the need for downline equipment for pipe straightening.
