QISI’s Electromagnetic Acoustic Transducer (EMAT) allows thickness measurements of boiler tubes effectively ignoring layers of slag and corrosion on the tube surfaces without couplant. This provides savings by eliminating sandblasting and cleaning services to the utilities.
The improvements since 1997 have provided increased power necessary to not only measure heavily scaled tubes but also chromized tubes. The technology has been successful at measuring tube wall thickness with an accuracy of +0.1mm through scale thickness as high as approximately ½ inch.
QISI technicians are supplemented with AutoCAD technicians to collect, download and import the data into a visual representation of your boiler. The software compares acceptability criteria with field data and identifies erosion and corrosion issues on the fireside of the boiler. Engineers and managers can use this data to better understand and track areas susceptible to early failure.
The elimination of sandblasting allows a utility to minimize their outage schedule, reduce costs and collect needed preventative and predictive maintenance data on the fireside surfaces without introducing silica to the fireside of the boiler.
