NON DESTRUCTIVE TESTINGS
I Controlli Non Distruttivi (CND) sono il complesso di esami e prove condotti impiegando metodi che non alterano il materiale e non richiedono la distruzione o l’asportazione di campioni dalla struttura in esame finalizzati alla ricerca ed identificazione di anomalie strutturali della struttura ...
THERMOGRAPHIC TESTING
The Infrared Thermography is the ability of instrumentations (thermal imaging cameras) to turn an infrared image into a radiometric image allowing to read the temperature values of an image. The thermal energy (infrared) is located in the not visible spectrum because its wavelength is too long ...
HEAT TREATMENTS
Rovergamma performs heat treatment furnace extrafurnace with resistance system both in yard and in the workshop by customers in pipes and vessels.
We have two devices to 12 outputs.
IDENTIFICATION OF MATERIALS
Using portable instrumentation, able to identify the alloying elements, we are able to recognize the material.

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 ...
