Inspection of CRA and cladded pipe

Pipelines made of CRA pipe (Corrosion Resistant Alloy) and cladded pipelines can now be inspected using a special high-resolution application of 3P Services’ DMR sensor technology (Direct Magnetic Response). Liner wall thickness and in particular a local lift-off of the liner from the internal surface of the carrier pipe can be located and sized accurately. The latter, an apparent thickening of the liner, indicates corrosion between liner and carrier pipe with the oxide kept in place.
