Abstract: A device for non-destructive testing of objects, particularly pipes in oil refineries, having a first positioning device for positioning a collimator including a radioactive radiation source near an object to be tested, and a second positioning device for positioning a film carrier near the object to be tested. The first positioning device may be anchored or placed with a lower end on a substantially flat base surface, wherein the collimator is attached to the opposite, upper end of the first positioning device. Before the exposure, the radiation source may be guided towards the collimator via a delivery tube such that no radiation is able to be emitted from the device during the placement of the first positioning device.

Abstract: Several, preferably three, deflection elements are placed and fixed around the wellhead, preferably in equal circumferential distances around the wellhead. For each deflection element a guiding cable is lowered with its head end from one or several, preferably three workspaces in the direction of the wellhead. Each guiding cable is looped with its head end through the corresponding deflection element, wherein each deflection element forms a point of reversal. Each guiding cable is pulled back with its head end side to the corresponding workspace while in return additional guiding cable is supplied and passed through the corresponding deflection element. A sealing element which is fastened to each guiding cable is lowered in the direction of the wellhead by pulling the guiding cables at their head end sides upwards and, in return, supplying the guiding cables in the direction of the wellhead on the lowering side.
