Advanced Non-Destructive Testing Methods



TGR Industrial Phased Array
Phased Array

This is the full featured system, B & C scan & Scanner with encoder capabilities. It has been approved by ASME & API 650 App U (UT in Lieu of Radiography).







TGR Industrial Computed Radiology
Computed Radiology

Computed radiology (CR) uses very similar equipment to conventional radiography exept that in place of a film to create the image, an imaging plate (IP) made of photostimulable phosphor is used.









TGR Industrial Eddy Current and Remote Field Eddy Current
Eddy Current Testing, Remote Field EC and NFT Fin Fan Testing

Eddy Current Testing is based on inducing electrical currents (eddy currents) in electrically conductive material. Any defect i nthe material - such as cracks, pitting, heat-treat variances, wall loss, or other discontinuity - will distrupt the flow of the eddy currents. The Remote Field Eddy Current method is a method for inspecting ferromagnetic tubes fro the inside using eddy currents. TGR uses highly sensitive multi-frequency eddy current instrumentation that detects these disruptions. Testing with multiple frequencies provides the best detection capabilities, from surface cracks to deep flaws, with speed & reliability. Near Field Testing (NFT) is designed specifically for fin fan carbon steel tubing inspection to detect internal corrosion, erosion and pitting.

TGR Industrial Corrosion Mapping and Monitoring
Corrosion Mapping & Monitoring

There are two techniques utilized in testing for Flow Accelerated Corrosion (FAC), first is a traditional grid layout with point readings, this requires a large volume of single point readings to be data logged & downloaded into excel & color formatted. The second method utilizes Phased Array Ultrasonic Testing, instead of a single point thickness reading you can acquire a continuous scan around the pipe with a 1.5" footprint. The Phased Array system can also display in "B" & "C" scan color formats for quick analysis.

TGR Industrial IRIS Testing
IRIS Testing

Digital IRIS stores the Ultrasonic thickness scan of each tube tested in B-scan, C-scan & circular modes of viewing.


Digital IRIS give you the capability to look through any tube you require.


Internal Rotary Inspection Systems (IRIS) is the ultimate in ultrasonic tubing inspection. Performance proven in millions of tubes in hundreds of plants worldwide, IRIS inspection is the efficient & reliable way to cut maintenance costs & virtually eliminate unplanned tubing failure.
