Phased Array Ultrasonic Testing (PAUT) is an advanced nondestructive examination technique that utilizes a set of ultrasonic testing (UT) probes made up of numerous small elements, each of which is pulsed individually with computer-calculated timing. This technique can be used to inspect more complex geometries that are difficult and much slower to inspect with single-angle probes. PAUT can be used to inspect almost any material where traditional UT methods have been utilized and is often used for weld inspections and crack detection. 

Compared to other forms of UT, PAUT has several advantages. PAUT can be conducted more efficiently than other forms, often within a fraction of a second. It can easily be used for repeat scans because it has a high degree of repeatability. By emitting beams of multiple different angles sequentially, PAUT can create detailed and accurate cross-sections of a part. It is also particularly useful in situations where there is less room for mechanical scanning because it’s able to sweep the beam without moving the probe.

Advantages of radiography testing (RT) include:

• No radiation source, eliminating boundaries and safety concerns
• Immediate, real-time results
• Precise location and sizing of defects, including width, length, depth, and overall size/volume

Highlights of Shear Wave:

• Ideal for structural inspection
• Corrosion detection
• Instant, accurate results
• Mitigate safety risks
• Code-compliant
• Environmentally safe

Shear Wave Ultrasonic Testing (UTSW), also known as "angle beam inspection" is an ultrasonic technique that's great for weld and joint examination. A probe consisting of an ultrasonic transducer with a plastic or Lucite wedge introduces an angled beam into the test area that can be adjusted by the technician. As the probe is moved back and forth along the area under inspection, it can detect discontinuities in the weld based on the refraction of the ultrasonic beam.

Carbon steel and stainless steel in general, however, have excellent sensitivity compared to their penetration depth; therefore, shear wave modes are generated and applied in general ultrasonic tests.

UTSW is generally used in structural and bridge applications, however, it has a variety of benefits in numerous industries. While this method gives you real-time results, the data that is collected is not encoded, therefore it cannot meet certain code requirements. This is when PAUT is best utilized.

Magnetic Particle Testing (MT), also referred to as Magnetic Particle Inspection, is a non-destructive test (NDT) technique used to detect surface and slightly subsurface flaws in most ferromagnetic materials such as iron, nickel, and cobalt, and some of their alloys. Because it does not necessitate the degree of surface preparation required by other nondestructive test methods, conducting MT is relatively fast and easy. This has made it one of the more commonly utilized NDT techniques. MT can be applied in both visible and fluorescent applications.

Liquid Penetrant Examination (LPE), also referred to as penetrant testing (PT), liquid penetrant testing (LP), and dye penetrant testing (DP), is a non-destructive test (NDT) method that utilizes colored dye to reveal surface flaws on parts and equipment which might not otherwise be visible. The technique works via the principle of “capillary action,” a process where a liquid flows into a narrow space without help from gravity. Because it is one of the easiest and least expensive NDT techniques to perform, PT is one of the most commonly used inspection techniques in many industries, including oil and gas. PT requires additional surface preparation and drying time when compared to MT.

Highlights of ICM:

• 100% elbow coverage
• Longitudinal scanning
• Instant, accurate results
• Works on 2" OD up-to-flat plate
• High-resolution data
• Environmentally safe

Internal Corrosion Mapping (ICM) detects degradation of metallic structures which can have a variety of causal factors and can display itself in many different ways. Corrosion inspection procedures evaluate the remaining wall thickness or the presence of mid-wall anomalies in pipework, pressure vessels or any metallic structure. By utilizing the latest technology from Olympus, the FlexoFORM Scanner can inspect a variety of configurations. Anything from a 2" OD pipe to a 16" 90° elbow can be captured in a fraction of the time compared to older technology; even with 100% coverage in most instances.

Highlights of CUI:

• Inspect through thick metal and insulation
• Save on insulation removal costs
• Real-time imaging for instant results
• One-touch automated reporting
• Range of application-specific probes
• Fast data acquisition

A method which maps material thickness using ultrasonic or eddy current techniques. Variations in material thickness due to corrosion internally or externally underneath insulation can be identified and graphically portrayed.

Our CUI services can scan through thick insulation, as well as aluminium, stainless steel, and galvanized steel weather jackets. It also benefits from a range of PEC-Array, single-element PEC, and application-specific probes to support various applications.
