Non-destructive Examination
Non-destructive Examination
Phased Array Ultrasonics (PAUT), Total focusing method (TFM), Plane Wave Imaging (PWI), Phase Coherence Imaging (PCI): These advanced ultrasonic testing techniques provide high-resolution imaging of welds and materials, allowing for precise defect detection and sizing.
Time of Flight Diffraction (TOFD): A highly accurate ultrasonic sizing technique that detects and sizes flaws in welds and materials by analysing the diffraction of sound waves at defect edges.
Medium and Long-Range Ultrasonics (MRUT and LRUT): These techniques enable the inspection of extensive pipeline networks and large structures from a single location, identifying corrosion, wall thinning, and cracks without direct access to the surface.
Guided Wave Phased Array: From a single position, the Guided-wave phased array system is capable of detecting wall thickness changes within plate-like structures. Ultrasonic waves are used to steer beams around the plate, creating radar-like scans to assess buried, insulated, or otherwise inaccessible areas.
Corrosion mapping with integrated robotic systems: Robotic crawlers equipped with ultrasonic sensors create detailed maps of components, assessing corrosion and allowing for targeted maintenance and asset preservation.
Corrosion Under Pipe Support Testing (CUPS): A specialized technique that inspects corrosion-prone areas where pipes rest on supports, which are common failure points in industrial facilities.
High Temp Hydrogen Attack (HTHA): This method assesses steel components exposed to high-temperature hydrogen environments, identifying microstructural damage that could lead to catastrophic failure.
Magnetic Flux Leakage (MFL) for storage tank floor designs: MFL detects corrosion and pitting in tank floors by analysing magnetic field variations, preventing leaks and environmental hazards.
Magnetic Testing (MT): Uses magnetic fields to detect surface and near-surface defects in ferromagnetic materials, commonly applied to welds and structural components.
Penetrant Testing (PT): A simple and effective method for revealing surface cracks and defects in non-porous materials through the application of a dye penetrant.
Eddy Current Testing, Eddy Current Array, Pulsed Eddy Current-Array (EC, ECA, PECA): Electromagnetic techniques used for detecting surface and near-surface cracks, corrosion, and material thickness variations in conductive materials.
Corrosion Under Insulation (CUI): Detects corrosion hidden beneath insulation layers without requiring insulation removal, reducing maintenance costs and downtime.
Stress Corrosion Cracking (SCC): Identifies cracking caused by the combined effects of stress and corrosive environments, a common issue in pipelines and pressure vessels.
Radiography (X-Ray, Gamma, Digital, Live View): These radiographic techniques provide internal imaging of welds and materials, detecting hidden flaws and ensuring structural soundness.
Leak Testing, Remote Visual Testing (Drone, ROV, Borescope, Infra-red): Various non-intrusive methods used to detect leaks and inspect inaccessible areas in pipelines, pressure vessels, and confined spaces.
Tube Inspection (IRIS, EC, ECA, RFT, NFA, NFT): Specialized testing techniques assess tube conditions in heat exchangers and boilers, identifying wall thinning, corrosion, and deposits that impact efficiency.
