Evaluation of FMC/TFM Performance for Volumetric NDT to Field Piping Welding
Volume 7: Seismic Engineering; ASME Nondestructive Evaluation, Diagnosis and Prognosis (NDPD) Division, 2023Abstract Ultrasonics (UT) is a volumetric Nondestructive Examination (NDE) method widely used all over the world and across various industries and has seen rapid improvement. One of the latest UT techniques, Full Matrix Capture / Total Focusing Method (FMC/TFM), shows great potential for piping welding NDE.

NDT of rods and pipes using shear wave caustics
Ultrasonics, 1986Abstract An important feature of shear wave insonification of circularly cylindrical samples is the caustic formations which occur inside the samples, after internal reflections at the external sample boundaries. Strong echoes are obtained from defects in the outer regions of the samples when they pass through these caustic regions because of the ...

Phased array ultrasonic NDT system for tubes and pipes
The Journal of the Acoustical Society of America, 2005One or more phased array ultrasonic probes in the shape of conical section arcs, or an entire conical section ring, emit beams at a fixed incident angle with respect to the outer surface of a tube or pipe under inspection. At any given moment, these beams strike the tube at a single small entry zone from number of different directions.

Holographic NDT methods for plastic pipe vibration and brittle crack propagation analysis
SPIE Proceedings, 1995Plastic pipes are frequently used for low pressure gas and water distribution. One of the main problems with their wide commercial applications is rapid crack propagation (RCP). This results in enormous losses of energy resources and environment pollution.

Holographic NDT On Pipes: Predicted Fringe Patterns And Experimental Results
SPIE Proceedings, 1986Holography has been used in the electric utility industry in practical tests for deformation of pipes subjected to repair procedures. In research studies, the use of holography for measurement and NDT (nondestructive testing) has been explored for pipes.

NDT Applied to the Detection of Defects in Oil and Gas Pipes: A Simulation-Based Study
Volume 2B: Advanced Manufacturing, 2015This research investigates the application of microwave nondestructive testing (NDT) to oil and gas pipe wall reductions (PWR) in manufacturing that are less than full-circumferential in extent. Pipes were modeled using Computer Simulation Technology (CST) simulation software, CST Microwave Studio holding pipe length, wall thickness, depth of PWR and ...
