Inspection of insulated vessels and piping has long been a major challenge. Conventional techniques such as profile radiography and ultrasonics are often impractical or cost prohibitive due to limited productivity, insulation removal cost, temperature restraints, etc. This paper will overview two innovative technologies that are designed for on-line corrosion inspection of insulated components- (1) Profiler portable real-time radiography (RTRT) and (2) RTD- INCOTEST pulsed eddy current. The practical applications, typical productivity, strengths and limitations of each technology will also be addressed.
