Full Body Phased-Array Ultrasonic Inspection

PTS introduced the first full-body phased-array ultrasonic inspection system (FBUT) in 2006 at our Channelview, TX facility. Since its introduction, this system has been used by many pipe manufacturers such as: Boomerang Tube, VAM Drilling and Tenaris, and is qualified for many end-users, including such as, Exxon, Chevron, Shell and BHP. PTS is certified to inspect a variety of products from these companies, and is currently the only 3rd party inspection company offering the phased-array FBUT system. Building on the continued success of the phased-array system, PTS expanded these inspection services with additional units in its Channelview, TX and Morgan City, LA facilities, as well as units at Boomerang Tube and VAM Drilling.

The ultrasonic phased- array system consists of a series of individual elements, each with its own connector, time delay circuit and A/D converter. Elements are pulsed in groups with pre-calculated time delays for each element, i.e. “phasing” to form software configurable wave-fronts. Beam size and shape are determined by the element characteristics and properties, the number of elements used to form the beam (aperture) and the applied timing delay parameters. Because the operator has software control over the probes’ parameters (i.e. angles and focal distance), the phased-array method is very effective in flaw detection and increasingly efficient in its speed of detection. The PTS phased-array inspection system software can combine wall mapping and OD dimensions in one simultaneous step. Phased-array UT method has become a forerunner the nondestructive testing industry.
