LRUT (Long Range Ultrasonic Testing)
By fitting a ring of transducers around the pipeline, a wave maker device directs low frequency (20-100 kHz) ultrasonic waves via the transducers, longitudinally into the pipeline wall. The method effectively detects changes in the pipeline’s cross-section, enabling it to indentify corrosion and other abnormalities. At the same time this provides the possibility of using welds and flanges as distance references.
Inspecta has qualified experts in using this method to help you get a cost-effective report on the condition of your pipelines.
The test results are displayed in an easy-to-interpret visual interface on a laptop computer – enabling us to draw conclusions quickly and correctly. Upon identifying a defect we carry out follow-up detailed testing of the affected area, using complementary ultrasonic or x-ray methods.
With this highly advanced testing method you will get an accurate status report of your pipelines in the most effective way.
Benefits of LRUT :
Corrosion Corrosion Mapping (UT C-Scan & B-scan)
Corrosion Mapping Provides precise thickness measurement and a virtual picture of the damage. It produces repeatable images displaying in top views (C-Scan) and sectional views (B-scan).
Phased Array Ultrasonic Testing (P.A.U.T):
Phased array ultrasonic testing uses multiple elements to steer, focus and scan beams with a single transducer assembly. Beam steering, commonly referred to sectorial scanning, can be used for mapping components at appropriate angles. This can greatly simplify the inspection of components with complex geometry. The ability to test welds with multiple angles from a single probe greatly increases the probability of detection of anomalies.
Time of flight Diffraction Ultrasonic Testing (ToFD):
TOFD technique is a real time imaging system that produces a cross sectional view (D-Scan) of the material tested. Two compression wave angled probes were placed in a pitch and catch configuration with a fixed Probe Center Separation (PCS), with one probe as the transmitter and the other as receiver. Defects are detected by the diffracted ultrasound wave occurring at the edges of defects..
Alternative Current Field Measurement (A.C.F.M):
ACFM is an electromagnetic testing capable of detecting and sizing surface breaking cracks in metals. The basis of the technique is that an alternating locally uniform current is induced to flow in the component being tested. Defect detection and sizing is based on the disturbance of uniform current due to the surface breaking cracks.
Remote Visual Inspection (R.V.I ) :
RVI tool(camera) was send through the small opening of the remote places and the internal images were sending back to the inspector’s observation screen, were the inspector can inspect & record the images.Test report is given with cd of recoded inspection video.
Internal Rotary Inspection System (I.R.I.S):
IRIS is the most instructive tube inspection method. This advanced inspection uses ultrasonic technology to measure wall thinning and pitting due to corrosion and erosion in the tubes.
