Non- destructive Inspection Methods used in the Oil and Gas Industry
There are five popular Non-destructive Testing Methods most commonly used in the Oil and Gas industry, which include: Visual Inspection, Ultrasonic Techniques, Radiography, Thermography, and Acoustic Emissions Testing.
Each of these methods is explained, followed by a qualitative discussion of its implementation.
1. Visual Inspection
Visual Inspection is an inexpensive method for detecting equipment flaws and defects.
A trained technician is likely to detect improper structural installations, certain types of impending structural failure, welding flaws, corrosion development, and cracks.
Ultrasonic Testing utilizes sound waves whose frequencies (50 kHz - 50 MHz) are above the audible range for the human ear.
The piezo-electric effect of the Ultrasonic Transducer makes it possible to transmit and receive from within the equipment.
The instrument makes it possible to inspect the internal structure of the equipment and to detect thickness changes, welds, cracks, voids, delamination, and other types of material or structural defects.
The limitation of this method is that data acquisition and evaluation depend on the expertise of the technician.
This makes it difficult to arrive at non-subjective readings and precision.
Radiographic Methods utilize X-ray or gamma rays (electromagnetic radiation) to examine the internal structure and integrity of the equipment.
Because these waves have short wavelengths, they can penetrate and travel through structural materials such as steel and metallic alloys.
In the oil and gas industry, this NDT Method is useful for inspecting welds on pipelines and pressure vessels.
It is also useful for inspecting non-metallic materials such as concrete and ceramics.
Operating this type of NDT requires conformance to safety regulations.
Thermographic Inspection measures the difference between the temperature of a pipeline and the surrounding environment.
The measurement helps to detect:
- Defects in pipeline insulation
- Leakage of oil or gas
The marriage of this NDT Technique and drone services will make this method of inspection more efficient and cost-effective.
This is used as a Visual Inspection solution for oily products.
It is crucial to evaluate the safety of lifting equipment involved in handling oily products within the oil and gas industry.
This ensures adherence to safety standards, focusing on preventing accidents and maintaining operational integrity.
It is an integral part of oil and gas inspection safety protocols.
