Boiler Tube Failure Analysis Case Study by technicalfrontier is a document available to read on EtoBox.
The failed boiler water wall tube was analyzed using various techniques to identify the root cause of failure. Visual inspection showed a wide window type rupture initiated from the external fillet weld with no corrosion signs. Chemical analysis found the tube composition matched specifications. Dimensional measurements found no significant wall thickness reduction. Fractography revealed fatigue fracture lines initiated from weld defects. The failure was caused by vibrational fatigue due to unstable fluid f
