Long Range Ultrasonic Testing (LRUT)
Long Range Ultrasonic Testing (LRUT), also known as guided wave ultrasonic testing is a fast and cost-effective method for inspecting long lengths of pipes. The technology is operated by placement of an array of probes (transducers) placed in the belt, circumferential wrapped around the pipe being inspected. The transducer then generates and receives low-frequency ultrasonic-guided waves longitudinally down the length of the pipe.
The returning echoes indicate defects such as corrosion and other abnormalities. Distance covered by the ultrasonic waves is dependent on a number of factors related to pipe coating, branch connections, and fittings and above-ground or buried locations. The system can inspect both directions from each inspection location and therefore can maximize production.
The benefits of LRUT are;
1) Screening long lengths of pipes at one time.
2) Inspection of 100% of pipe.
3) Detection of corrosion and erosion under the insulation of pipes.
4)Analysis of pipes at different access locations such as wall penetration, road crossing and buried sites.
5) Screening of on and offshore pipework, even in tightly packed racks.
6) Riser inspection.
