LRUT Guided Wave Ultrasonic

LRUT (Long Range Ultrasonic Testing) is a method for thickness measurement where a clamp is mounted on the outside of the pipe. The method enables scanning of the entire pipe, including areas between the pipe and hangers/supports, which can otherwise be difficult to access.

The scanning identifies areas of corrosion or other anomalies, which can then be examined in more detail if needed. The method is suitable for pipes with dimensions from 1 inch and upwards.

IKM Inspection has extensive experience with the use of this equipment, including in collaboration with the Norwegian Armed Forces, and has a large number of its own certified operators.

 

PIT (Pipe Inspection Tool)

PIT is an inspection tool that enables complete (100%) scanning of pipes with diameters up to 60 inches, with a sensitivity down to 0.2 mm.

The tool detects corrosion both internally and externally, quantifies the damage, and indicates the exact position in the pipe, for example “154 metres at the 12 o’clock position”.

As far as we know, we are the only ones who can provide this service in collaboration with our partner Applus+. We can inspect pipes down to 700 metres below sea level (m.b.s.l.) and over lengths of up to 30–40 km.

From 2026/2027, equipment will be available that can handle pipe dimensions up to 4.8 metres.

 

DTI Trekscan

DTI Trekscan is used for thickness measurement of pipes from 4 inches and upwards. The system provides a highly accurate scan of the pipe, with a sensitivity down to 0.2 mm for both internal and external corrosion.

The method enables scanning at speeds of up to 1 metre per second for pipes with wall thicknesses from 1.5 to 60 mm.

The equipment can also be used for cleaning and video inspection, and is widely used on assignments for the Norwegian Armed Forces.
