Corrosion Under Insulation
Corrosion Under Insulation – No Problem?
MB Inspection has an exclusive agreement with RTD bv to provide the RTD-Incotest system in the United Kingdom and Ireland.
INCOTEST (an acronym for INsulated COmponent TEST) formerly known as ARCO-TEMP, is a unique corrosion survey method that allows ferrous pipes and vessels to be surveyed without the time and expense of removing insulation, asbestos, fireproofing concrete or similar coatings. The system will operate under the following challenging conditions, without disturbing the insulation or coating:
The diameter of the footprint varies between 25 and 150mm and is dependent on wall thickness and thickness of the insulation.
The detection of corrosion through coatings, concrete and marine growths were also quickly identified as good applications. Surveying heavily corroded pipes on which grinding, needed for an ultrasonic survey, would not be safe has also proved a successful application.
New applications are constantly emerging, as people realise the big benefits from this technology. One of the attractive features of Incotest is its tolerance with regard to coupling the signal to the object. Holding the probe at the right location is sufficient; as a result measurements can be taken in demanding circumstances. For example, on offshore risers and caissons using rope access or by divers or ROV underwater to a depth of 10m.
