TenarisConfab orders AGT expander from SMS Meer Confab S.A. 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 one 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.Compared with solutions to date, the new development achieves a better straightening effect by over bending. Furthermore, the load on the expander tool is minimized. The system is designed for pipe diameters up to 30 inches. For larger diameters the whole units can be separated from the machine. This also allows simple tool changing.
