Olympus FlexoFORM Scanner
The innovative FlexoFORM™ scanner makes challenging pipe elbow corrosion inspection easier. With flexible phased array technology, one probe is all you need to cover the full range of elbow diameters.
Pipe elbows are susceptible to damage, such as from flow-accelerated corrosion (FAC). However, inspecting them poses unique challenges. Because their surface shape changes from convex on the extrados (outside curve) to concave on the intrados (inside curve), and because many diameter standards exist, ultrasonic testing to evaluate damage in the elbow was limited to doing spot check thickness measurements using probes with small footprints.
The FlexoFORM™ solution solves the challenges of pipe elbow inspection and enables 100% coverage with intuitive C-scan imaging. The solution integrates flexible ultrasonic phased array probe technology and a water column in a scanner that is easy to use and offers high productivity
Quickly measure the wall thickness of elbows
100% elbow coverage for a high probability of detection
High-resolution data (1 mm × 1 mm)
Intuitive 2D C-scan imaging
Small-diameter wedge series - Used to inspect pipes with diameters smaller than 4.5 in. Users can manually scan the extrados of elbows or pipes from 1.3 in. OD up to 4 in. OD. The wedge can be fitted with a Mini-Wheel™ encoder to create an encoded one line scan.
High-Resolution Data - The FlexoFORM scanner is used with an OmniScan® MX2 or SX flaw detector to acquire and save data with a resolution as high as 1 mm × 1 mm to detect and measure different types of damages or anomalies such as remaining wall thickness, corrosion pitting, and mid-wall lamination or inclusions. The high-density data combined with the multiple views available directly in the flaw detector or through OmniPC™ software provide clear images of the pipe material’s condition and make data interpretation faster and easier. Because the entire surface of the elbow is covered, the FlexoFORM solution is less dependent on the operator and provides an improved probability of detection as compared to simple spot checking
Wedges - Along with the scanner’s wedges, a wedge series for small-diameter pipes and a series for automated rastering two-axis scanners are also available. All wedge series use the same flexible array probe.
