NDT & Inspection RTD INCOTEST Key advantages of RTD INCOTEST RTD INCOTEST provides a reliable solution for a variety of applications. • RTD INCOTEST enables the detection of CUI (Corrosion Under Insulation) and FAC (Flow Accelerated Corrosion). • Riser average wall thickness can be gauged without removing marine growth, neoprene or Monel. • Non-contact ‘dry’ wall thickness measurements can be carried out even with dirty, coated rough and/or high temperature object. • The robust design of RTD INCOTEST is electrically, although not intrinsically safe. • Operation is possible across a wide range of climatic conditions with consistently high levels of reproducibility. • Measuring through any non-conductive or non-magnetic material, RTD INCOTEST detects and calculates average general levels ofcorrosion or erosion and provides an instant site report in a measuring matrix format. RTD INCOTEST is the fast, accurate and reliable way of surveying ferrous pipes and vessels - through their thermal insulation. In operation, it does not disturb insulation or coatings and provides accurate results through aluminium, stainless or galvanized steel claddings.With RTD INCOTEST, insulation may be hot or cold, wet, rough or encrusted, irregular or heterogeneous or even with wire mesh.Through its excellent repeatability, RTD INCOTEST is ideally suited for baseline and periodic monitoring surveys.
