Penetrant liquid testing
Then the excess penetrant is removed.
At the end of this procedure, wich occurs by washing, removal with wet rags or immersion in emulsifiable liquid, the surface should be free of traces of penetrating. Finally, the detector is applied (in the same way it has been applied the penetrant), it will allow the penetrated liquid to resurface superficially.
It will be possible, in this way, thanks to the action of capillarità, detect to the examined piece any defects surfaced. Typically the penetrant is red, while the detector is white; this chromatic difference lets be readily seen any defect outcropping. Rovergamma carries out penetrant fluorescent testings too.

Magneto inductive testing
Magneto inductive testing: the test consist of verification of the conservation status of wire ropes; the control allows to detect anomalies (breaking of wires, corrosion, etc.) inside of the rope not found with the only visual inspection. -
Visual inspection
The visual inspection is a test that allows to put in evidence any geometric, dimensional and of operation anomalies of a given component under construction or in service.
The test may be conducted mainly in two different ways:- Direct visual examination, where the operator has direct ...

Leak Detection
Rovergamma carries out testings to detect possible loses with leak detection mainly on welds of tank’s ground (with methodology of “vacuum box”) and on welds of pressure vessels (welds of tube-tubesheet, reinforcements on nozze, etc.). The testing consists in putting pressure or in vacuum the ... -
Radiographic testing
The Radiography is the technique which keeps image of the content of an object by the impression of a sensitive element, film, by ionizing radiation (X or gamma rays).
The mechanism of image formation is associated with the different absorption of radiations in the piece in function of the ... -
Ultrasonic Testing
This kind of Non Destructive Testing detects discontinuities in the tested piece being able to establish the nature, the position and the depth of the same. Rovergamma carries out ultrasound testings on laminates forged, forgings and welds; also performs testings through thickness measurements ... -
Magnetoscopic Testing
This kind of Non Destructive Testing can be carried out only on ferromagnetic components. A piece or a ferromagnetic component, if subjected to magnetization, highlights outcropping discontinuities on the surface, or placed immediately below it (few millimeters) which create a dispersion of the ... -
Penetrant liquid testing
The Non Destructive Testing with Penetrant Liquids is an inspection procedure of the surface integrity of a ferrous or non ferrous piece and, possibly, superficially non-porous during the testing. The penetrant is applied by spraying, brush or immersion allowing capillary action to act for the ...
