Ultrasonic Inspection

Ultrasonic Thickness is an NDT method for measuring the thickness of materials on vessels, tanks, piping, structural steel, etc. UTT is used to measure corrosion, erosion, and mechanical damage. The data is collected and then used to assess the remaining life of the component to ensure continued service. It can also help to determine if repair work or replacement of components is needed. UTT testing is fast, reliable, and accommodating by using handheld portable devices.  

Ultrasonic Shear Wave (SW) is sometimes referred to as “angled beam ultrasonic testing” is a portable method that is used mostly for weld inspection in pipes, pressure vessels, plates. The probe conducts an ultrasonic beam at an angle into the test area, moving back and forth as it detects any flaws based on the refraction of the ultrasonic beam. SW is quicker and safer compared to performing X-ray due to there is no radiation, shut down of work in area due to radiation exposure or environmental hazards. SW is great for cracks, lack of fusion, lack of penetration in welds. 

Phased Array Ultrasonic Testing (PAUT) is an advanced NDT method that use a probe with multiple small transduces that are individually pulsed. PA units are very portable and provides a cross section view that can reveal defects inside the material of pipe, tanks, vessels, or welds. PAUT is used to detect flaws that cannot be easily found with radiography and manual ultrasonic testing and allows faster examination and results. PA data can be displayed in multiple views such as A, B, C, and S scans that results in a more accurate interpretation of flaw(s). The data can be stored so it can be reviewed or given to the Client/Customer for future reference. PAUT is quicker and safer compared to performing X-ray due to no radiation, shut down of work in area due to radiation exposure or environmental hazards. This method detects discontinuities such as cracks, lack of fusion, lack of penetration, slag.
