Finding the Root Cause of Boiler Tube Failur

Failures are catastrophic, thick-lipped failures that initiate from ID cracks that are oriented perpendicular to the direction of the stress. Causes: Tube damage occurs due to the combination of thermal fatigue and corrosion. Corrosion fatigue is influenced by boiler design, water chemistry, boiler water oxygen content, and boiler operation. > Get A Quote >
