NON-DESTRUCTIVE TESTING FOR THE OIL & GAS INDUSTRY:-
Most Popular Inspection Techniques for the Oil and Gas Industry:-
a) Equipment for running petroleum products (such as a pipeline) can be inspected without making any structural changes.
b) Equipment is not harm during NDT therefore there is not a reason to shut down not to interrupt operations.Which NDT technique used depends a great deal on what needs inspecting.
Some inspection method are more effective than others at providing certain information.
The most commonlyNDT methods used for inspecting oil and gas equipment are:-
- VISUAL INSPECTION.
- ULTRASONIC TECHNIQUES.
- RADIOGRAPHY TESTING.
- LIQUID PENETRANT TESTING.
- MAGNETIC PARTICLE INSPECTION.
- EDDY CURRENT TESTING.
- ACOUSTIC EMISSION TESTING.
- LEAK TESTING.
- PAUT (Paut array ultrasonic testing).
- TOFD ( Time of flight diffraction)
- GUIDED WAVE TESTING.
- ELECTROMAGNETIC ACOUSTIC TRANDUCER TESTING.
- AUTOMATIC INSPECTION.
ULTRASONIC INSPECTION METHOD?
Ultrasonic testing make use of sound waves whose frequencies (50 kHz - 50 MHz) that don’t listening by the human ear.
The piezoelectric material effect in the ultrasonic transducer makes it possible to transmit and receive from within the material. The ultrasonic probe makes it possible to inspect the internal material of the equipment, and to detect thickness change, welds, cracks, voids and other types of material or structural defects. The limitation of this method is that data acquisition and evaluation depends on the expertise of the engineer. This makes it difficult to come at nonsubjective readings and precision.
