Permits scanning up to +/-100m on pipes using Long Range UT techniques. No fixed diameter rings needed.

MRUT and LRUT techniques comparison inspection in pipes and tubes


  • Magnetostrictive strip material can be cut to any diameter. No need to have individual rings for different diameters. The strip weighs less than 1Kg and fits in a small backpack.
  • Standard kit covers all pipe schedules up to 24”. Additional ribbon sensors available to cover diameters up to 48” and above.
  • Very fast and quick installation. No need to pressurize the transducers. Surfaces only need slight sanding and inspections can run on painted surfaces.
  • Low profile for limited access locations. This is of particular relevance for pipe racks with limited spacing between them.
  • Single transducer for the whole pipe perimeter, reducing drastically maintenance, spares and repair costs.
  • Superior signal-to-noise ratio (SNR) to piezoelectric rings (+10-20dB).
  • Axisymmetric ring provides a homogeneous wave front with a minimum blind zone (more uniform loading of sound in the pipe).
  • Fast pipe screening using a single axisymmetric collar. Additional focusing using a separate receiver and scanner.
  • Permits using the same instrument to perform MRUT inspections.
  • High-temperature tensioner for inspections up to 300C.

Software Upgrades

  • LRUT LITE (fast screening)
  • LRUT FOCUS (focusing around the pipe).
