NON-DESTRUCTIVE METHOD FOR INNER SCALE MEASURING …

MEASURING OXIDE SCALE THICKNESS ON THE INNER SURFACE OF A BOILER TUBE USING ADVANCED ULTRASONIC METHOD. A significant limiting factor that affects tube life in fossil fired steam boilers is the growth of iron oxide scale (magnetite) on the inside and outside tube surfaces. Whi le external scale limits heat transmission into the tube and reduces boiler efficiency, internal scale build-up represen ts …

Thickness Measurement Technology using Cable-less Inner …

In consideration that bore oxide thickness ≥300 microns is the threshold at which operational problems (tube conduction efficiency, overheating, spallation & blockage etc.) are likely to start manifesting themselves, oxide thickness measurements of this level and below (down to 125 – 150 microns) can be achieved ultrasonically, and avoid the need for tube cutting.
