Remote Inspection of Welds and Map Corrosion

Cost savings of inspections by the reduced use of scaffold construction and removal, Elevated Work Platforms hire & rope access time.

LMATS  announce the addition of a motorized steerable scanning solution to its line of advanced NDT solutions for ultrasonic, phased array testing and corrosion mapping, SteerROVER™.

Inspect at heights without expensive scaffolding. Steer to hard-to-reach areas thanks to the scanner’s two pods with independent motors and four strong magnetic wheels.

Remote Weld Inspection
The LMATS motorized steerable scanning solution SteerROVER™ can inspect welds when configured:

  • Longitudinal welds on pipes as small as (305 mm) 12 inches and up to flat
  • Internal, circumferential pipe range: 24 in. (610 mm) and above
  • Circumferential pipe diameter range: 2.75 in. (70 mm) up to flat

Laser vision enables the unit to keep the weld being inspected in the centre of the probe thus maintaining an accurate scan.

Remote Corrosion Mapping

When configured and fitted with a motorized raster arm, the LMATS motorised steerable scanner SteerROVER™ is a powerful solution for corrosion inspection in remote locations.

LMATS now offers a 3D image of the Remote Corrosion Mapping

The red heat map indicates areas of less than 2.5mm remaining wall thickness.

Data analysis of the linished patches revealed locations as low as 1.3mm remaining wall thickness.

Remote Visual Inspection
When fitted with digital still and video cameras, the LMATS motorised steerable scanner SteerROVER™ enables visual inspections in hard to get to places without the expense of EWP's, Ropework, scaffolding or drones.

The magnetic wheels provide the necessary traction to perform scanning at heights, such as on large pressure vessels or tanks and pipework.

Remote Inspection Features:

  • Versatile steerable remote-control scanner to perform PAUT, TOFD, PEC, ECA, LFET, EMAT & visual inspection using various probes/camera holder configurations.
  • Test speed – 15m/minute max. in ideal conditions
  • 600mm scan width at 760mm/Sec in ideal conditions.

Remote Inspection Advantages:

  • Improve safety by eliminating rope access work
  • Reduce the cost of scaffold, EWP & rope access time
  • Consistent & high-speed examination decrease onsite time and maintenance cost for the asset owner
  • 100% coverage scanning mapped & recorded.

Remote Inspection Applications:

  • Corrosion, erosion, wall loss, thickness mapping & weld assessment on storage tanks,
    • Pressure vessels
    • LPG Spheres
    • Overhead piping
    • Mining wear chutes
    • Wear plates
    • Marine hulls when in drydock
    • wherein a scaffold, EWP or rope access is required to access the examination area.
  • Risers, vertical piping, structural columns & beams
  • Scanning on overhead pipes >70mm OD
  • Scanning internally on pipes >610mm ID.

Remote Inspection Limitations:

  • Unsuitable on non-ferromagnetic tanks
  • However non-ferromagnetic pipes can be scanned using a chain attachment and drive system
  • Unsuitable underwater applications
  • Maximum 10kg payload capacity.
