Abstract: A method is provided for determining the geometry of one or more real, examined defects of a metallic and in particular magnetizable object, in particular a pipe or a tank, by means of at least two reference data sets of the object generated on the basis of different, non-destructive measuring methods.
Abstract: An inspection device for examining pipelines is provided, and comprises a sensor carrier which in operation is rollable through the pipeline. The sensor carrier has an at least essentially circular circumference in a cross section that runs transverse to an axis of rotation. The sensor carrier also has at least one sensor unit. The sensor carrier further comprises at least one stabilizing means, preferably a multitude disposed along the circumference.

Abstract: A pig is provided for use in pipelines filled with a flowing fluid. The pig includes a pig body, a drive element which may be a propeller disposed on said pig body which can be rotated by the flowing fluid. The pig also includes a generator unit connected to the drive element through which a movement of the drive element may be converted into electrical energy, and a locking means through which the position and/or the speed of the pig inside the pipeline may be fixed. The generator unit is designed to operate as a motor through which the drive element may be made to rotate and which is designed to set a speed for the pig that is different from the flow velocity of the flowing fluid inside the pipeline and that the pig is provided with an energy storage unit for electrical energy, which is connected to the generator unit.
