The Long Range Guided Wave Ultrasonic Technique (LRGUT) is designed to inspect 100 percent of a pipe segment from one 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 or pipe feature, they mode convert into laminar waves and reflect back to the tools original location. Using a laptop these signals are digitally captured. The time-of-flight for each signature is calculated to determine it's distance from the tool. The cross sectional area is calculated by amplitude and then the circumferential extent determined by the focused beams (broken down in octants) to determine the significance of the defect.
TCR Arabia performs LRGWUT in association with its international partner. This partner meets and exceeds the PHMSA 18 points to examine casings and crossings.
LRGWUTs primary application is within the Oil and Gas Refining, Petrochemical, Storage, Offshore and Pipeline Transportation industries used to inspect difficult to access piping systems such as:
Insulated Pipe in Refineries
Offshore Pipeline Risers
Cased Road or Railway Crossings
Loading Lines and associated Pipe work
Tank Dyke Pipeline Crossings
Above Ground or Buried Flow Lines
River or Bridge Pipeline Crossings
