Automated Ultrasonic Testing (AUT) in Lieu of Radiography Testing (RT) Ultrasonic testing in lieu of radiography has proven very effective for pressure vessels, tanks, piping, and other weld configurations. Evident ultrasonic weld inspection solutions comply with ASME, API, and other radiography replacement code requirements, such as full raw data collection and the use of an encoder. Compared to conventional radiography, our ultrasonic weld inspection solutions offer multiple benefits: > No radiation safety hazards > Helps eliminate work area disruption > Real-time digital archiving of...

Small-Diameter Pipes The COBRA™ manual scanner, combined with the OmniScan™ phased array (PA) flaw detector, is used to perform circumferential weld inspections on small-diameter pipes. The COBRA scanner holds up to two PA probes for inspections on pipes with outside diameters ranging from 0.84 in. to 4.5 in. (21 mm to 114 mm). With its very slim design, this manual scanner is used to inspect pipes in limited-access areas where minimal clearance is required. Adjacent obstructions, such as piping, supports, and structures, can be as close as 12 mm (0.5 in.). This scanner uses multiple links...

Scanning Methods Two-Sided Inspection One-Sided Inspection The COBRA™ scanner with the OmniScan™ MX2 and X3 flaw detectors are capable of two-sided inspection to cover both sides of the weld with only one pass for greater productivity. For these inspections, the scanner holds two phased array probes placed on either side of the weld; the distance between the probes can be adjusted to quickly adapt to different weld thicknesses. For pipe-to-component inspections, the scanner can be configured to perform one-sided inspections using a single probe. Evident also offers a more affordable COBRA...

Pipes and Plates Our versatile solution for weld inspections uses a variety of techniques to achieve a productive and efficient inspection on plates and pipes from 4.5 in. OD and up. Phased array, time-of-flight diffraction, and conventional ultrasonic techniques can be used alone or in combination to achieve full coverage of a weld with a high probability of detection. This solution also includes different scanning methods for accurate defect positioning and sizing. The stability and encoding capability offered by scanners results in better data quality and enables code compliant...

Ultrasonic Weld Inspection Solutions Brochure - 8

Austenitic and nickel-based alloy weld metals and other coarse-grained anisotropic materials affect ultrasound propagation causing beam distortion, beam scatter, mode conversions, and significantly increased attenuation resulting in a poor signal-to-noise ratio (SNR) as compared to shear wave inspections in low-alloy carbon steels. Inspection of these materials requires the use of dual phased array probes with TRL (transmit-receive longitudinal) wedge designs that acoustically insulate the transmitter and receiver beams for improved defect SNR and elimination of wedge echoes. Our Dual...
