The Long Range Guided Wave Ultrasonic Technique was designed to inspect long section of piping from a single location.  Torsional or longitudinal guided waves are induced into the pipe body and propagated along the pipe segment being inspected.  When these guided waves identify an anomaly of pipe feature they mode convert into laminar waves and reflect back to the tools original location.  Using a laptop these signals are digitally captured and processed.  The time-of-flight for each signature is calculated to determine the distance from the tool and the significance of the anomaly.  The octants determine the position around the pipe.
 

We have done some guided wave projects, including:
• Iranian offshore oil company,
• National Iranian gas company, Fajr jam refinery, jam
• Terminals & Tanks petrochemical company, Asalouye.
• Terminals & Tanks petrochemical company, Mahshahr.
• Iranian offshore oil company, Siri Island
