Advanced Nondestructive Testing solutions provide a number of (NDT) services, such as phased array, corrosion mapping, and long range ultrasonics, time of flight diffraction; high-temperature hydrogen attack detection of hydrogen induced cracking along with tube inspection and alternating current field measurement or ACFM.
The Complete Set of Advanced Nondestructive Testing Services
Phased array for scanning material strength and thickness
Ultrasonic phased array applications are found in many industrial areas, storing a full record of inspection like A-Scan, B-Scan, C-Scan and S-Scan visual displays that help devise a simple way of understanding the type of flaw and its dimensions.
The phased array differs from standard manual ultrasonic techniques in its ability to examine and analyse large volumes of materials and welds from one location thus helping the inspection of geometries that would prove to be difficult otherwise.
Additionally, it can be used alongside manual encoded scanning devices. This versatile technique means that it can be used in large applications which range from piping and butt welds in vessels to the flanges and sweeps lets.
Time of flight diffraction in offshore applications
TOFD or Time of flight diffraction is a technique that measures and identifies the locations of structural flaws. It is different from the usual pulse echo ultrasonics as it is based on diffracted energy instead of reflected energy.
It is also dependant on time-based, low-energy diffracted signals, which can be received from the tips of flaws in materials. This helps to determine the exact size and position of the flaw which needs to be accurately imaged and measured.
Because this method is not reliant on amplitude, unlike standard ultrasonics, it is also unaffected by restrictions which include the law orientation, uneven or changing material surfaces, or poor couplings and probe location.
Corrosion mapping of offshore equipment
The condition of equipment can be analysed properly with the help of automated ultrasonic imaging systems.
The process is the best way to accurately test the thickness of walls in the piping and large areas of vessels while the system continues to operate minus the high costs of a shutdown. On a standard working day, around 30m² can be inspected.
In-situ metallographic services and replication
In-situ metallurgy evaluation helps perform a comprehensive assessment of the microstructure of components. The process is often known as the field replication of metals and can find out about the overall strength and durability of the materials.
This non-destructive method of inspecting also helps discover any kind of defects, cracking or anything which compromises with the material’s integrity.
Tube inspection services
This kind of tube inspection specialises in eddy current and ultrasonic techniques for both ferrous and non-ferrous tubing. The techniques include a number of technologies such as eddy current testing (ECT, non-ferrous tubing); remote field technology (RFT, ferrous tubing); internal rotary inspection system or IRIS, ultrasonic testing all materials.
By minimising sudden failures at power plants, a large number of scheduled shutdowns can be averted and operations can remain uninterrupted.
These are some of the advanced tube inspection services you should certainly know about.
