ELIMINATION OF MAIN STEAM BOILER TUBE FAILURES CAUSED …

This paper describes corrective action taken on USS MARS in the AFTS 1 Class to eliminate main steam boiler tube fatigue failures caused by resonant vibration conditions. The failures resulted from violent "harpstring like" bending vibration of the approximately 14‐foot long, one‐inch O.D. boiler tubes excited by propeller blade rate hull vibration.

What causes failure of boiler tube? - FindAnyAnswer.com

18/4/2020 · Furthermore, why do boiler tubes fail? Causes: Short-term overheat failures are most common during boiler start-up.Failures result when the tube metal temperature is extremely elevated from a lack of cooling steam or water flow. A typical example is when superheater tubes have not cleared of condensation during boiler start-up, obstructing steam flow.
