RE: Ethylene furnace convection

Googling brought this response from the Hendix Group website (always informative):

"Depending on the configuration of the finned tubes, you might consider boroscope inspection. Ultrasonic wall thickness (IRIS) inspection may also be a possibility, depending on the diameter of the tubes. Finned BFW tubes are difficult to inspect and you may have to sacrifice one or two properly selected ones."

Hope this helps.

Smart pigging will work if you are looking for UT scanning. RT/UT at 180 degree bends. Visual inspection for bowing and fouling.

What are you looking for?
